Why is this serum different?

Serolys is the first European serum formulated according to the long-duration bio-fermentation protocol used in Korean pharmacies for 30 years. Unlike conventional serums that only use standard ingredients, our four main active ingredients (hyaluronic acid, niacinamide, squalane, peptide complex) are produced by bacterial fermentation over 60 to 90 days. This technique transforms the size of the molecules so that they genuinely penetrate the skin instead of remaining on the surface. This is why Korean women aged 55 are, on average, 8 years ahead in terms of skin health compared to European women of the same age. Serolys replicates this science in France, at an intermediary-free price.

Will it work on my skin?

Serolys has been specifically formulated for menopausal and post-menopausal skin, meaning skin that has lost collagen, radiance, and elasticity after the age of 50. The formula is suitable for all skin types (dry, combination, sensitive, mature), including skin that has become reactive during menopause. Soothing active ingredients (Bisabolol, Panthenol) have been carefully dosed to eliminate any risk of irritation. The serum's pH is calibrated to respect the delicate hydrolipidic film of 50+ skin. If you have particularly sensitive skin, we recommend a patch test on the inside of your elbow for 48 hours before the first application to your face. Among the 45,000 women who use it, less than 0.3% have reported reactivity, which places Serolys among the best-tolerated serums for this age group.

How to use it?

Morning and evening, on clean, dry skin. Dispense 1 to 2 pumps into the palm of your hand, then distribute with fingertips over the face, neck, and décolleté using light upward movements. Avoid the immediate eye area. Gently massage until fully absorbed, which takes approximately 30 seconds. The serum is non-greasy and does not interfere with makeup: you can use it under your foundation in the morning without transfer or pilling. The first radiance effects are visible within 2 to 3 weeks. Effects on dark spots and firmness require 6 to 12 weeks to be fully visible, which is the physiological time for cell renewal after 50 years of age. A 30 ml bottle lasts approximately 1 month with twice-daily application.

Designed for your skin

A serum that adapts to your menopausal skin

Unlike generic serums designed for younger skin, Serolys Super C is formulated specifically for skin over 50. Bio-fermented active ingredients penetrate where your skin needs them most, without irritation, stinging, or leaving a sticky film.

 

The result looks like your skin. Just brighter, more rested, more even. Not a mask, not an "overdone" effect, not a false youth plastered on your face. Simply your rediscovered radiance.

Suitable for all skin types

How it works

The Science Behind Long Fermentation

Our formula relies on intelligent active ingredients that adjust to your skin the moment you apply them. At first touch, the serum is neutral and cool. As you massage it into your face, bio-fermented peptides are released in a cascade, delivering amino acids where your skin needs them.

 

The result: more even, smoother, perfectly nourished skin. No complicated routine. No layering. Just one effortless step.

FREQUENTLY ASKED QUESTIONS

Your questions, our answers

How to apply it?

Step 1: Prepare Your Skin

Start with clean, dry skin. Cleanse your face with your usual cleanser, then gently pat dry with a clean towel. For optimal results, apply Serolys to slightly warm skin, just after evening makeup removal or morning shower, when pores are most receptive.

 

Step 2: Dispense Correctly

Dispense 1 to 2 pumps of the bottle into the palm of your hand. No more. Too large a dose will not improve results and may weigh down the skin. As the bio-fermented serum is ultra-concentrated in active ingredients, a few drops are enough to cover the face, neck, and décolletage.

 

Step 3: Apply in Upward Motions

Using your fingertips, spread the serum over your face with light, upward motions, from the chin to the forehead, always moving against gravity. Focus on marked areas: nasolabial folds, around the lips, crow's feet. Don't forget the neck and décolletage, areas that betray age first. Avoid the direct eye contour where the skin is thinner.

 

Step 4: Allow to Penetrate Then Seal

Gently massage for about 30 seconds until fully absorbed. The serum penetrates quickly and leaves no sticky film. Wait one minute before applying your usual moisturizer over it. In the morning, you can then apply your makeup without fear of transfer or pilling.

 

Recommended frequency: morning and evening, every day, for at least 3 months for complete and lasting results.

How long until I see results?

The first effects on skin radiance and luminosity are visible after 2 to 3 weeks of morning and evening use. Effects on dark spots and firmness require 6 to 12 weeks to be fully visible, which is the physiological time for cell renewal after age 50. A minimum 3-month course of treatment is recommended for lasting results. Be patient: menopausal skin renews itself more slowly, and Serolys precisely compensates for this slowness.

How long does one bottle last?

A 30 ml bottle lasts approximately 30 days with twice-daily application (morning and evening). If you use it only in the evening, it will last 60 days. For a complete treatment and lasting results, we recommend daily use for at least 3 months, which corresponds to the 3-bottle pack.

Is it compatible with my usual cream?

Yes, absolutely. Serolys should be applied first on clean skin, before your usual moisturizer. The serum penetrates the deep layers of the dermis thanks to its bio-fermented active ingredients, and your cream then seals in this hydration on the surface. If you also use a classic vitamin C serum, it's not necessary: Serolys already contains a more powerful stabilized vitamin C.

Will it be suitable for my sensitive skin?

Serolys was specifically formulated for menopausal and post-menopausal skin, which often becomes more reactive. The formula is fragrance-free, alcohol-free, silicone-free, and the pH is calibrated to respect the fragile hydrolipidic film of skin over 50. Soothing active ingredients (Bisabolol, Panthenol) have been dosed to eliminate any risk of irritation. Out of 45,000 users, less than 0.3% reported reactivity. If your skin is particularly sensitive, we recommend a patch test on the inside of the elbow for 48 hours before the first application on the face.

How does the 365-day warranty work?

If Serolys does not meet your expectations, you can return the bottle to us within 365 days of your purchase, even if it is completely empty, and we will refund your entire order. This is what we call the "empty bottle guarantee". To activate the refund, simply send an email to our customer service with your order number. We process refunds within 5 business days of receiving the bottle. Over 99% of our customers never request a refund.

Is there a hidden subscription?

No, never. Serolys operates on a one-time purchase basis only. You pay once, you receive your order, and nothing else happens. No automatic debits, no surprise reshipments, no commitments. If you wish to repurchase serum, you place a new order manually whenever you decide.

What are the shipping costs and delivery times?

Free delivery in mainland France on all orders over 50€. Home delivery charged at 4.90€ for orders under 50€. Ships within 24 to 48 hours after payment validation, from our logistics center. Standard delivery in 3 to 5 business days.

Where is it made?

Serolys is entirely formulated and manufactured in France, in a laboratory specializing in high-end cosmetics. All our active ingredients comply with the strictest European standards. The brand spent 18 months collaborating with a Korean partner to adapt the long-duration bio-fermentation protocol to European menopausal skin, but the final formulation and production are 100% French.

Can I use it under my makeup?

Yes, it's even recommended. Serolys is a non-greasy serum that absorbs in about 30 seconds without leaving a sticky film. Apply it in the morning to clean skin, wait a minute for it to penetrate, then apply your moisturizer and foundation as usual. The serum does not cause transfer or pilling, and does not alter makeup hold. On the contrary, many of our customers report that their foundation applies more evenly thanks to the deep hydration provided by the serum.

The story

Seoul, South Korea. Year 1980

In the early days of Korean cosmetic laboratories, researchers observed a puzzling phenomenon. Women working in the fermentation workshops for traditional medicinal plants had hands and faces that were visibly younger than their actual age. This discovery would change the world of cosmetics.

 

Twelve years of biochemical studies later, science understood: the long fermentation of cosmetic active ingredients produces bioactive peptides and amino acids that penetrate the skin and reactivate cellular synthesis. Korean cosmetics companies massively embraced this discovery. Forty years later, 90% of premium Korean serums contain fermented active ingredients. In France, almost none.

 

Our laboratory spent eighteen months collaborating with a Korean partner to adapt the long-duration bio-fermentation protocol for menopausal European skin. Serolys Super C is the result of this work.
