Why is this serum different?
+Serolys is the first European serum formulated using the long-duration bio-fermentation protocol that has been the gold standard in Korean pharmacies for 30 years. Unlike conventional serums that rely on standard ingredients, our four key actives (hyaluronic acid, niacinamide, squalane, peptide complex) are produced through bacterial fermentation over 60 to 90 days. This process transforms the molecular size so the actives truly penetrate the skin rather than sitting on the surface. It's the reason Korean women at 55 are, on average, 8 years ahead of European women of the same age in terms of skin condition. Serolys reproduces this science in Europe, at a direct-to-you price.
Will it work on my skin?
+Serolys was specifically formulated for menopausal and post-menopausal skin, meaning skin that has lost collagen, radiance and bounce after 50. The formula suits all skin types (dry, combination, sensitive, mature), including skin that has become reactive since menopause. The soothing actives (Bisabolol, Panthenol) are dosed to eliminate any risk of irritation. The serum's pH is calibrated to respect the fragile hydrolipidic film of skin over 50. If your skin is particularly sensitive, we recommend a patch test on the inner elbow for 48 hours before your first facial application. Of the 45,000 women using it, fewer than 0.3% have reported any reactivity, making Serolys one of the best-tolerated serums in this age group.
How do I use it?
+Morning and evening, on clean, dry skin. Dispense 1 to 2 pumps into your palm, then smooth with your fingertips across the face, neck and décolletage using gentle upward strokes. Avoid the immediate eye area. Massage gently until fully absorbed, which takes about 30 seconds. The serum is non-greasy and won't interfere with make-up: you can use it under foundation in the morning with no transfer or pilling. The first glow effects are visible within 2 to 3 weeks. Effects on dark spots and firmness take 6 to 12 weeks to become fully visible, which is the natural cell-renewal cycle after 50. A 30 ml bottle lasts roughly one month when used twice daily.

Susan W.
61, Bristol★★★★★"Five products in my bathroom cabinet, and now I only use this one. My pharmacist confirmed it: one complete serum is worth more than five average ones. My skin is thanking me."

Dorothy R.
67, Chester★★★★★"At 67, I wasn't expecting much. After two months, my husband told me I looked well rested. He had no idea I'd switched serums."

Janet M.
63, York★★★★★"My jawline had been dropping since I turned 60. Three months after starting Serolys, my husband asked if I'd been to the hairdresser. I hadn't done anything else at all."

Helen L.
54, Cambridge★★★★★"Four years trying every vitamin C serum from the chemist with nothing to show for it. My dermatologist had suggested laser treatment at £1,500. With Serolys my dark spots faded in 8 weeks."

Rosemary D.
60, Norwich★★★★★"I retired last year and felt like I'd aged overnight. My daughter gave me Serolys for my 60th birthday. My former colleagues at the Christmas lunch couldn't believe it was just a serum."

Elizabeth P.
58, Oxford★★★★★"After 32 years of marriage I thought my husband no longer looked at me the same way. One evening he asked, quite seriously, whether I'd had injections. It's just a Korean serum and he still refuses to believe it."
A serum that adapts to your menopausal skin
Unlike generic serums designed for younger skin, Serolys Super C is formulated specifically for skin after 50. The bio-fermented actives penetrate where your skin needs them most, without irritation, without stinging, without leaving a sticky film.
The result looks like your skin. Just brighter, more rested, more even. Not a mask, not an overdone look, not a false youth plastered over your face. Simply your natural glow, restored.

The science behind long-duration fermentation
Our formula relies on intelligent actives that adjust to your skin the moment you apply them. On first touch, the serum feels neutral and cool. As you massage it into your face, the bio-fermented peptides release in a cascade, delivering amino acids exactly where your skin needs them.
The result: smoother, more even, perfectly nourished skin. No complicated routine. No layering. One single, effortless step.

The mechanism
How bio-fermentation works on your skin
A precise science that repairs what menopause has switched off, in four physiological steps.
Step 1
Cellular depletion
After menopause, the skin loses up to 70% of its cutaneous vitamin C and 30% of its collagen within five years.
Step 2
90-day fermentation
The actives are fermented for 60 to 90 days, producing molecules far more absorbable than their native form.
Step 3
Reactivation
Bioactive peptides act as cofactors in collagen synthesis. The skin starts producing again.
Step 4
Visible results
Glow within 15 days. Dark spots fading at 6 to 8 weeks. Smoother texture at 3 months.
Clinical results
Independent study, 8 weeks

Frequently asked questions
Your questions, answered
How do I apply it?
+Step 1: Prepare your skin
Start with clean, dry skin. Cleanse your face with your usual cleanser, then pat gently with a clean towel. For the best results, apply Serolys to slightly warm skin, right after removing make-up in the evening or after your morning shower, when the pores are most receptive.
Step 2: Use the right amount
Dispense 1 to 2 pumps into the palm of your hand. No more. Too much won't improve results and may weigh the skin down. Because the bio-fermented serum is ultra-concentrated, a few drops are enough to cover the face, neck and décolletage.
Step 3: Apply in upward strokes
With your fingertips, smooth the serum across the face using gentle upward movements, from chin to forehead, always working against gravity. Pay extra attention to marked areas: nasolabial folds, lip contour, crow's feet. Don't forget the neck and décolletage, the areas that show age first. Avoid the immediate eye contour where the skin is thinnest.
Step 4: Let it absorb, then seal
Massage gently for about 30 seconds until fully absorbed. The serum sinks in quickly and leaves no sticky film. Wait a minute before applying your usual moisturiser on top. In the morning, you can then apply your make-up without any risk of transfer or pilling.
Recommended frequency: morning and evening, every day, for at least 3 months for full, lasting results.
How long until I see results?
+The first effects on radiance and glow are visible within 2 to 3 weeks of twice-daily use. Effects on dark spots and firmness take 6 to 12 weeks to become fully visible, which is the natural cell-renewal cycle after 50. A minimum 3-month course is recommended for lasting results. Be patient: menopausal skin renews more slowly, and that slowness is precisely what Serolys is designed to address.
How long does a bottle last?
+A 30 ml bottle lasts roughly 30 days with twice-daily use (morning and evening). If you use it only in the evening, expect around 60 days. For a full course and lasting results, we recommend daily use for at least 3 months, which corresponds to the 3-bottle bundle.
Can I use it with my usual moisturiser?
+Absolutely. Serolys is applied first on cleansed skin, before your usual moisturiser. The serum penetrates the deeper layers of the dermis thanks to its bio-fermented actives, while your moisturiser then locks in that hydration on the surface. If you currently use a separate vitamin C serum as well, you won't need it any more: Serolys already contains a stabilised vitamin C that is more potent.
Is it suitable for 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. The soothing actives (Bisabolol, Panthenol) are dosed to eliminate any risk of irritation. Of 45,000 users, fewer than 0.3% reported any reactivity. If your skin is particularly sensitive, we recommend a patch test on the inner elbow for 48 hours before your first facial application.
How does the 365-day guarantee work?
+If Serolys doesn't meet your expectations, you can return the bottle within 365 days of purchase, even if it's completely empty, and we'll refund your entire order. This is what we call the "empty-bottle guarantee". To request a refund, simply email our customer service team with your order number. We process refunds within 5 working days of receiving the bottle. Over 99% of our customers never ask for a refund.
Is there a hidden subscription?
+No, never. Serolys operates on a one-off purchase basis only. You pay once, receive your order, and nothing happens after that. No automatic payments, no surprise re-shipments, no commitment. If you'd like to reorder, you simply place a new order manually whenever you choose.
What are the delivery costs and timescales?
+Home delivery from £4.95. Dispatched within 24 to 48 hours after payment confirmation, from our fulfilment centre. Standard delivery takes 3 to 5 working days.
Where is it made?
+Serolys is entirely formulated and manufactured in Europe, in a laboratory specialising in premium cosmetics. All our actives meet the strictest European standards. The brand spent 18 months in collaboration with a Korean partner to adapt the long-duration bio-fermentation protocol to menopausal European skin, but the final formulation and production are 100% European.
Can I wear it under my make-up?
+Yes, and we actually recommend it. Serolys is a non-greasy serum that absorbs in about 30 seconds without leaving a sticky film. Apply it in the morning on clean skin, wait a minute for it to sink in, then layer your moisturiser and foundation as usual. The serum causes no transfer, no pilling, and doesn't affect the wear of your make-up. In fact, many of our customers report that their foundation goes on more smoothly thanks to the deep hydration the serum provides.

Seoul, South Korea. 1980
In the earliest Korean cosmetics laboratories, researchers noticed something remarkable. The women working in traditional medicinal-plant fermentation workshops had hands and faces that were visibly younger than their real age. A discovery that would change the world of skincare.
Twelve years of biochemistry research later, the science caught up: long fermentation of cosmetic actives produces bioactive peptides and amino acids that penetrate the skin and reactivate cellular synthesis. Korean cosmetics seized on this discovery. Forty years on, 90% of premium Korean serums contain fermented actives. In Europe, barely any.
Our laboratory spent eighteen months in collaboration with a Korean partner to adapt the long-duration bio-fermentation protocol to menopausal European skin. Serolys Super C is the result of that work.
