All about the skin

The arrival of winter is often accompanied by dry skin, redness, tightness… but for people with psoriasis, it is much more than a simple cosmetic inconvenience.

Cold weather, dry air, lack of light, or heating systems can promote the flare-up of psoriatic plaques.

In this article, we'll explore the effect of winter on psoriasis and, more importantly, the small steps you can take to limit its impact!

1. Understanding your psoriasis

Psoriasis is a chronic inflammatory skin disease characterized by hyperproliferation of keratinocytes, local inflammation, and impaired skin barrier function.

In summary, the epidermal renewal cycle is accelerated (in just a few days), which leads to the accumulation of scales (which form the plaques).

The interaction between your genetic, immune, and environmental factors triggers or modulates flare-ups. In other words, psoriasis is sensitive to the surrounding environment, and winter is a particularly “aggressive” time.

2. Why do psoriasis symptoms often worsen in winter?

Decreased humidity and dry skin

Cold air naturally contains less water vapor, leading to reduced ambient humidity. This dryness is felt on the skin's surface, which loses more moisture, and the skin barrier weakens.  

When the skin barrier is compromised, irritants and allergens can penetrate more easily. As a result, inflammation is triggered and psoriasis flare-ups occur.

The interior heat

Indoor heating (radiators, forced air, stoves) exacerbates the drying effect of the environment. The air goes from "dry outside" to "very dry inside," and this double effect further weakens your skin.

Less UV light & reduced vitamin D

Sunlight, and in particular UV (moderate UVB), has a beneficial effect on psoriasis via immunomodulatory action (reduction of T cell activation) and stimulation of cutaneous vitamin D synthesis, which plays a role in local immune regulation.

In winter, there is less sunshine, shorter days, and more "oblique" rays: all of this reduces natural exposure to useful UV rays.

As a result, our skin suffers, at least as much as our mood!

3. Habits to avoid in winter if you have psoriasis

In winter, certain natural habits should be avoided to prevent aggravating psoriasis! We know, taking a hot bath is tempting, but very risky…

• Showers or baths that are too hot

• Harsh cleaners (perfumed soaps, unsuitable pH)

• Irritating clothing (raw wool, rough synthetic fabrics)

• Excessive heating, lack of humidification

• Neglecting or insufficiently moisturizing your skin

• Stress, lack of natural light

4. How to take care of your skin in winter?

Choosing the right skincare products

• Choose creams like our Mother-of-Pearl Cream enriched with BIONACRE, promoting deep skin hydration and renewal.
  

• Apply your skincare products immediately after showering, while your skin is still slightly damp.
  

• Reapply hydration several times a day if needed.
  

• For very thick/scaly areas, targeted treatments such as our Kerato-Reducing Emollient Treatment can be incorporated .

Limit physical and mechanical aggression

• Opt for lukewarm (not hot) showers of moderate duration (less than 10 minutes).
  

• Use gentle, sulfate-free cleansers with a pH close to the skin, such as our Lipid-Replenishing Cleansing Oil .
  

• Do not rub with towels: pat gently
  

• Avoid rough clothing and direct contact with wool against the skin (use a cotton or silk layer underneath).
  

• Cover up (gloves, scarf) to limit direct exposure to wind or freezing cold

Winter should not be the “psoriasis season”, but rather a time to anticipate, strengthen the skin barrier, and adapt skincare routines so that you no longer fear it.

Cold weather acts as a catalyst for skin stress: dryness, lack of light, heating, and mechanical aggressions. But with a consistent strategy and appropriate skincare, it's possible to no longer dread winter and its impact on psoriasis!

Discover our anti-itch treatments

A moisturizing cream doesn't last forever. Like any cosmetic product, it has an expiration date that is important to respect, both for the effectiveness of its active ingredients and for the health of your skin.

A changing texture, an altered odor, or even invisible bacteria can transform your beauty routine into a minor dermatological risk.

So, how long can you actually keep your moisturizer on ?

The difference between DLU and PAO: two key points to know

• BEST BEFORE END (Use By Date) : This is indicated on some unopened cosmetics. It is the date until which the product is guaranteed to be stable and effective.
  

• PAO (Period After Opening) : Represented by a small open jar followed by a number (e.g., 6M , 12M , 24M ) as you will find on our Blue Skincare packaging. This means that the product can be safely used for 6, 12, or 24 months after opening .
  

On average, a moisturizing cream can be kept for 6 to 12 months after opening .

What are the signs that it's time to throw away your cream?

Even if the PAO (period after opening) is not reached, certain signs should alert you and prompt you to put your moisturizer aside:

• The texture has changed (more grainy, more liquid, lumps forming)
  

• The color has changed (yellowing or discoloration)
  

• The smell becomes unusual or unpleasant
  

• Tingling or redness may appear after application.
  

In this case, it is best to stop using it immediately.

How to extend the life of your moisturizer?

When you love something, you don't count the cost! And we love that our jar of Crème de Nacre lasts a little longer.

A few simple steps can help your skincare product last longer:

1. Close the jar or tube tightly after each use
   

2. Avoid dipping dirty fingers directly into the jar: make sure to use the product with clean hands
   

3. Store the product in a dry, temperate place , away from heat and direct light.

4. Respect the dates indicated on the packaging.
   

The unique nature of Blue Skincare products

At Blue Skincare , our BIONACRE® -based products are formulated to be effective and safe while respecting sensitive skin, and we always recommend using them within 6 to 12 months of opening to guarantee optimal effectiveness (although they are often finished sooner!).

Each product features a small pictogram of an open jar, followed by a number of months (e.g., 12M). This indicates how long the product can be safely used after opening.

And if you still have any doubt about the storage of your moisturizing cream, don't hesitate to contact our online advisor Billie, who will be happy to advise you!

You spent the summer perfecting a magazine-worthy golden tan, and now, by September, it's already threatening to disappear. Frustrating, right? We agree!

Rest assured: there are tips for extending your tan beyond your vacation. And dietary supplements are among the most effective allies, provided you choose them wisely.

Why does tan fade so quickly?

Before getting into the heart of the matter, a quick reminder: tanning is a natural defensive reaction of the skin . Exposed to UV rays, it produces melanin to protect itself. But once you return to the office (and under often somewhat gray skies), the melanin renews itself less quickly, the skin dries out and the tan eventually disappears.

According to dermatologists, without special care, the tan begins to fade 2 to 3 weeks after the last exposure.

The key to keeping it? Hydrate, protect, and support skin from within.

What nutrients prolong tanning?

Certain active ingredients play an essential role in boosting and prolonging the golden glow:

• Beta -carotene : A precursor to vitamin A, it stimulates melanin production and helps maintain a luminous complexion for longer. It's found in carrots, apricots, and melon. So, in short: almost all the foods we stop eating once the school year begins!

• Vitamin C and vitamin E : two star antioxidants that neutralize free radicals generated by the sun. The result: less oxidative stress, and therefore a tan that doesn't turn dull too quickly.
  

• Zinc : It contributes to healing and cell regeneration. A real ally for keeping skin clear and even after summer.

• Essential fatty acids : they strengthen the skin barrier, prevent dryness and prolong the radiance of the tan.

The food supplement to prolong your tan

We also don't want our tan to disappear as soon as we step back into the office. This is one of the reasons why we created our Skin Perfector food supplement , which helps us feel soothed all year round.

Why is it so effective?

• Our Skin Perfecting supplement combines Active Mother-of-Pearl + zinc + vitamin C + hyaluronic acid to protect cells against oxidative stress. A winning combination!
  

• It promotes more even skin , less prone to spots and irregularities after summer.
  

• 90% of users report seeing improved skin quality from the first month of treatment .

In short: when you go back to school, taking care of your skin also means taking care of it from the inside out. There's no magic pill or miracle cure, but real daily support so that your tan doesn't fade as quickly as your holiday memories!

All summer long, our skin feels good: smooth, even, beautifully tanned, almost photoshopped by the sun. And then comes back to school. Within days, the imperfections return, sometimes worse than before. We call this the rebound effect , and if you've ever experienced it, you know how frustrating it is.

But don't panic: understanding why it happens is the first step to avoiding the surprise return of post-summer spots.

During summer: the illusion of perfect skin

Under the sun, the skin changes rhythm:

• UV rays have a temporary anti-inflammatory effect , which calms redness and reduces spots.
  

• Tanning and thickening of the stratum corneum mask small imperfections.
  

• Sebum circulates differently because of the heat, and pores appear less visible.
  
  

The result: skin looks more beautiful, clearer... but it's only a facade. Behind the scenes, dead cells accumulate, pores become clogged, and sebaceous glands work in overdrive.

After the summer: the backlash

At the start of the school year, when sun exposure decreases and the skin resumes its normal cycle, everything that was “put on hold” during the summer resurfaces:

• Accumulated dead cells block the evacuation of sebum.
  

• Inflammation returns, accentuated by back-to-school stress and pollution.
  

• Result: pimples, blackheads and blemishes galore.
  
  

This is why we tend to experience breakouts in the weeks following the end of summer, even when we don't necessarily experience acne the rest of the year.

How to limit the rebound effect?

Fortunately, this is not inevitable. A few simple reflexes can help limit the damage:

1. Gently cleanse : there's no point in stripping skin that's already weakened by the sun. What it needs is a treatment that helps gently remove excess dead skin cells and prevents pores from clogging. Our Kerato-Reducing Emollient Treatment is ideal for smoothing, softening and preventing roughness, without being harsh.
   

2. Moisturize regularly : Tight skin overproduces sebum to defend itself. Remember to moisturize it morning and evening with a small amount of Mother-of-Pearl Cream.

3. Focus on restorative and rebalancing active ingredients : zinc, minerals, antioxidants, etc. to calm inflammation and support the skin barrier. Active ingredients contained in our Skin Perfecting Food Supplements.

4. Adopt a regular routine : a gentle daily routine is better than an overly aggressive “shock treatment.” With a good routine, the effects become visible quickly.

To support the skin in this critical back-to-school phase, we have created a 30-day Reset Pack , with treatments designed to soothe, rebalance and strengthen the skin barrier !

There's nothing like a day at the beach to unwind and reset your thoughts. But for your skin, it's a whole different story! Between the sun, salt, sand, and wind, our skin can come out dehydrated, dull, or marked.

The result: tightness, loss of radiance, and a feeling of discomfort. Even more problematic in cases of psoriasis or eczema!

The good news? With a few targeted actions and the right products, it's possible to quickly restore comfort, flexibility, and brightness. So the beach remains a pleasure!

1. Rinse and soothe skin immediately

After the beach, the priority is to remove salt, sand, chlorine and sunscreen residue . These elements, left too long, dehydrate and irritate our skin.

So two essential actions when returning from the beach:

• Opt for a lukewarm shower , not a hot one (hot water accentuates dryness).

• Use a gentle cleanser that preserves the hydrolipidic film, without sulfates or perfume. Our Gentle Cleansing Oil is like a creamy bath, to prolong relaxation.

2. Focus on deep hydration

After prolonged sun exposure, the skin loses a large amount of water. This dehydration causes the tightness, dryness, and dullness we try to avoid at all costs.

For this, there’s no secret, you have to hydrate!

• Moisturize generously , morning and evening, with a texture adapted to your skin.
  

• Opt for formulas rich in restorative active ingredients (active mother-of-pearl, ceramides, essential fatty acids) to restore the skin barrier.
  

• Apply to skin that is still slightly damp to seal in moisture.
  

Our Mother-of-Pearl Cream , enriched with active mother-of-pearl, ideal for sensitive skin, immediately soothes and repairs deeply.

3. Stock up on antioxidants

Sun exposure generates free radicals that accelerate skin aging. Antioxidants are your best allies to limit these effects.

• Adapt your plate by favoring red fruits, citrus fruits, green vegetables, nuts, for an internal antioxidant intake.
  

• Integrate our Skin Perfecting Supplements into your routine to stock up on zinc, vitamin C and plant extracts to support regeneration and preserve radiance from within.

And last reminder: pampering your skin after the beach is important, but it shouldn't be limited to summer!

These actions (gentle cleansing, hydration, antioxidants, targeted care) must be part of our routine throughout the year, to offer our sensitive skin the comfort it deserves!

The sun, the salt, the chlorine... Summer leaves behind some lovely memories, but it also leaves skin feeling tired: tightness, dryness, pigment spots, roughness... The good news? With a few targeted actions, you can help your skin regenerate and regain its natural radiance before going back to school!

1. Recharge the skin with water and comfort

After summer, the first priority is to deeply moisturize. Sun exposure tends to weaken the hydrolipidic film, the natural shield that retains water and protects the skin from external aggressions. The result: tightness, dry patches, and a wrinkled appearance.

Before going back to school, it's time to switch to a comforting routine: choose skincare rich in moisturizing agents, capable of penetrating deeply, but also restoring the skin barrier to prevent water from evaporating immediately.

The idea is to restore suppleness and soothe the skin after the harsh summer weather.

Our Mother-of-Pearl Cream , inspired by the ancestral formula of Gallien Cerat, intensely nourishes without a greasy effect and restores instant comfort. Its richness in minerals from mother-of-pearl helps to repair and smooth the skin day after day, to soften this return to serious things a little!

2. Gently restore radiance

Tanning gives you a healthy glow, but it often comes with a small drawback: the buildup of dead skin cells, which dulls your complexion and makes your skin rough.

Rather than weakening it with exfoliation, it is better to help it renew itself gently with kerato-reducing treatments, capable of targeting these specific areas while respecting the skin's balance.

The right thing to do? Use the Kerato-Reducing Emollient Treatment , ideal for smoothing and softening thickened areas, reducing roughness and restoring soft, even skin without irritation.

3. Pamper your skin from the inside and out

Skin doesn't repair itself solely with surface treatments. After weeks of sun exposure, it needs to regain its balance deep down.

Diet and lifestyle are just as important: good hydration (water, infusions), a diet rich in antioxidants (red fruits, tomatoes, nuts) and restorative nights allow the skin to regenerate better.

To complete this balance, this is where dietary supplements come in, capable of supporting skin regeneration from the inside out. By providing the body with specific active ingredients, they help the skin better defend itself against free radicals, stimulate its renewal, and maintain its radiance despite returning to daily life.

Our Blue Skincare Skin Perfecting Supplements treatment , formulated to strengthen natural defenses, boost hydration and promote smoother, brighter skin, even after summer.

This holistic approach is essential for prolonging the radiance of your tan while limiting the appearance of small pigment spots or fine lines caused by the sun. It's also a way to support the skin against the oxidative stress accumulated during the summer!

In summer, psoriasis experiences a strange paradox: the sun can soothe it... but also aggravate it if exposure is poorly managed.

Between heat, sweat, salt water and outdoor activities, skin needs support to get through the season without itching.

It's decided, psoriasis isn't going to ruin summer: here are our tips for enjoying the sun while taking care of your skin!

1. Take advantage of the benefits of the sun intelligently

Good news: UVB rays from the sun can reduce the thickness and inflammation of psoriasis plaques . This is the principle of certain dermatological phototherapies.

But the exposure must remain measured and progressive:

• Favor quiet hours (before 11 a.m., after 5 p.m.)
  

• Limit the first sessions to 10-15 minutes,
  

• Cover areas not affected by psoriasis to prevent sunburn
  

Too much sun can cause a rebound effect and worsen the lesions. So the watchword: moderation!

2. Maintain constant (and targeted) hydration

The sun, sea water or chlorine dehydrate the skin, which promotes itching and flaking.

Daily hydration is therefore essential, morning and evening, and even more so after swimming.

Our targeted treatments help maintain this permanent hydration, even in extreme heat:

• Our Kerato-Reducing Emollient Treatment helps smooth rough areas, reduce flakes, and soothe feelings of discomfort. Its fluid texture absorbs quickly, perfect for summer.

• The Mother-of-Pearl Cream , rich in restorative active ingredients, restores the skin barrier and maintains hydration over time, without perfume or greasy finish.

Choosing your cream for psoriasis

3. Minimize summer irritations

In summer, psoriasis can also be exacerbated by perspiration, friction from clothing or micro-irritations (sand, salt, chlorine).

To limit these triggers, here are some practical tips:

• Wear loose-fitting clothing made from natural fibers,
  

• Rinse skin with fresh water after each swim,
  

• Avoid harsh soaps and prefer gentle cleansers.
  

Little freshness tip: Isotonic Mother-of-Pearl Water spray to refresh, soothe, and remineralize the skin throughout the day. Ideal for slipping into your beach bag or tote bag!

When you suffer from psoriasis, every change of season raises questions. But summer, and more specifically sun exposure, is particularly worrying. Do UV rays (really) improve my patches? Or, on the contrary, could they worsen the inflammation?

Spoiler: it's all about the right balance, skin type... and preparation! Let's take stock together so you can make the most of summer.

The sun, a natural ally (under certain conditions)

Good news: In many cases, the sun can actually relieve psoriasis symptoms . This isn't a myth; it's even recognized by dermatologists.

The cause? UVB rays, which slow the excessive proliferation of skin cells (one of the mechanisms behind the famous plaques). Moderate and regular exposure can therefore:

• Reduce the thickness and redness of plaques

• Soothe the itching

• Visibly improve the overall condition of the skin

Moreover, certain phototherapies used in dermatological practices are based on this principle.

But be careful: it all depends on your skin (and your exposure)

Sun doesn't mean a miracle cure. There are essential precautions to take , because poorly managed exposure can have the opposite effect: worsen irritation, cause sunburn, and in some cases, trigger a rebound effect .

Mistakes to avoid at all costs in summer with psoriasis:

• Exposing yourself for too long or too abruptly, especially without preparation.

• Forget the areas not affected by psoriasis (which are also sensitive).

Thinking that sun = no need for treatment. Treatment doesn't take a vacation!

Our advice for living well in the sun with psoriasis

At Blue Skincare , we support sensitive skin, especially those prone to mild to moderate psoriasis. Here are some simple steps to enjoy the sun without risking irritation to your psoriasis :

1. Prepare your skin in advance

Avoid exposing dry, flaky, or damaged skin. It's best to implement a gentle routine to reduce flakes, improve skin texture, and make it more sun-tolerant.

For this, our Kerato-Reducing Emollient Treatment is particularly suitable: it helps smooth rough patches , deeply moisturize , and reduce inflammation without attacking. The perfect ally for your skin before going out in the sun!

2. Hydrate, hydrate, hydrate

The sun dehydrates , even if it temporarily improves the appearance of the plaques.

For this reason, use moisturizers morning and evening to maintain skin balance. The Mother-of-Pearl Cream , easy to carry, in a suitcase or your beach bag, will be the perfect ally to avoid tightness.

3. Listen to your skin

Every skin is unique. What works for one person may not work for another. A personalized diagnosis can help you understand your skin's specific needs.

Summer is here, and the call of the sun is irresistible. But before you lay down your towel and head out to get a tan, there are a few (big) mistakes to avoid.

Some seemingly harmless habits can actually weaken the skin and harm its long-term radiance . Here are 3 pitfalls to avoid for a healthy, long-lasting tan... and skin that will thank you!

Mistake #1: Not preparing your skin for tanning

We tend to believe that exposing ourselves to the sun is enough to tan. ERROR!
Your skin needs a little workout before starting its peak season. Like an athlete before a competition.

Why? Because the sun attacks, dries out, and oxidizes. And the more the skin is attacked, the worse it will react: tightness, redness, roughness, scales, etc.

So what good habits should you adopt? Start a preparatory routine 2 to 3 weeks before exposure . This involves gentle exfoliation, good daily hydration, and a course of food supplements.

Our Kerato-Reducing Emollient Treatment is perfect for gently removing dead cells, smoothing the skin and preparing the ground for tanning.

Our tips for preparing your skin for tanning

Mistake #2: Skipping hydration

The sun, the wind, salt or chlorinated water... So many factors dry out the skin! The result: a peeling tan, tightness, and a loss of radiance.

A good habit to adopt during the summer : moisturize morning and evening, before, during, and after exposure. Choose light textures, enriched with restorative and soothing agents.

The Nacre Cream is the ideal summer partner, to keep skin soft and luminous until bedtime (and its size means you can slip it everywhere, starting with your beach bag!)

Mistake #3: Neglecting the neckline, hands, or ears

These are areas that we often forget about, and yet they are the first to show signs of photoaging: pigment spots, premature wrinkles, loss of firmness, etc.

So rather than just taking care of your face, we focus on your entire body and integrate antioxidant- rich treatments into our routine to strengthen the skin against free radicals.

Enriched with restorative minerals, Isotonic Mother-of-Pearl Water is perfect for a quick mist on those forgotten areas throughout the day!

We've all heard of Glass Skin, its mirror-like glow and its many precise steps. We've seen Dolphin Skin, Cloud Skin, and even Jello Skin... But this summer, a new trend is setting the TikTok charts ablaze: Humidity Skin .

More natural, Humidity Skin does not seek to hide the reality of the skin, on the contrary: it enhances it.

So, what exactly is this trend and how can you embrace it without looking like a disco ball? We'll explain everything.

Humidity Skin: What is it exactly?

In line with the “skincare is the new makeup” movement , Humidity Skin no longer seeks to hide the skin under layers of makeup. On the contrary, it covers it with hydration, until it… overflows!

Unlike the varnished finish of Glass Skin , the result here is more organic: pearly skin, full of hydration (deep down), moist as if after a yoga session, a swim or a long walk in the sun. All this, without any filter or makeup clogging the pores.

A routine that focuses on hydration and simplicity

No need for endless layering to achieve credible skin moisture. The secret? A simple, sensory routine focused on deep hydration with:

• melting or slightly gelled textures , which hydrate without saturating
  

• soothing and rebalancing active ingredients
  

• and above all, skin that breathes

At Blue Skincare, this philosophy echoes our approach to simpler, more natural skincare, inviting us to get back to basics. Providing skin with what it truly needs to function at its full potential. Nothing more. Nothing superfluous.

Humidity Skin: Which products can help you achieve it?

To achieve that vibrant glow and truly hydrated skin, we recommend opting for:

• a treatment that hydrates without clogging , like Crème de Nacre : light, non-greasy, and enriched with restorative active ingredients.
  

• a formula that rebalances skin prone to flakes or roughness , like the Kerato-Reducing Emollient Treatment, ideal for keeping skin smooth in the middle of summer.

• and a revitalizing mist like our Isotonic Mother-of-Pearl Water , which leaves that fresh, hydrated finish you're looking for!
