I'm trying out the serum

7 reasons why Ageless Platinum Serum will transform your skin daily

We've meticulously examined C-DERMA by Céline's Ageless Platinum Serum. Our goal: to uncover the marketing promises behind the formula. We found something else: documented active ingredients, in vivo testing, 100% Swiss manufacturing — not promises, but proof. Rated 4.4/5 by over 1,700 satisfied customers, this serum has become a staple in daily routines.

Here are the 7 reasons, backed by evidence.

From Céline Staubli — Founder of C-DERMA

1. Proven in vivo efficacy, not just promises

The results of the Ageless Platinum Serum were measured by in vivo instrumental tests: -1.8 years of skin aging in 1 month*, +24% skin tonicity*, and +56% epidermal hyaluronic acid*. 94% of users observed firmer skin in 4 weeks, and 91% saw a more radiant and rested complexion from the first month.

2. An immediate lifting effect, from the very first application

Upon application, the skin is visibly tightened: marine active ingredients (microalgae + polysaccharides) create an immediate tightening effect. In vivo instrumental measurements (SkinCam) show instantly smoothed skin* — 4x smoother immediately after the first application**.

3. Biomimetic active ingredients that your skin recognizes

Biomimetic active ingredients replicate components naturally present in the skin to strengthen its functions without disturbing its balance. Their strong affinity with the skin allows for immediate recognition and optimized efficacy: hyaluronic acid (sodium hyaluronate), squalane, and biomimetic peptides support hydration, the skin barrier, and repair.

4. Intense dual hydration, without a greasy feel

The formula combines water (hyaluronic acid) and the lipid barrier (squalane) for dual deep hydration, providing up to 8 hours of continuous moisture. No greasy film: the texture is suitable for normal, dry, combination, and mature skin, for use morning and evening on clean skin.

5. Colloidal platinum, an antioxidant active ingredient rarer than gold

Colloidal platinum protects the skin from oxidative stress and daily aggressors, preserving its natural radiance. It is combined with Coenzyme Q10, which restores firmness and vitality to skin that has lost its tone, and iris stem cells that support skin renewal.

6. Made in Switzerland, Swiss Label certified

From scientific research to bottling, each step is carried out in Switzerland. Since 2020, C-Derma has been Swiss Label certified: local manufacturing, clear and traceable origin, rigorous quality controls at each stage of production in a certified Swiss laboratory.

7. 100% vegan, cruelty-free

The formula is 100% vegan, paraben-free, mineral oil-free, and clinically tested. No C-DERMA by Céline cosmetic is tested on animals or contains ingredients of animal origin: the brand prioritizes alternative, equally effective testing methods.

I'm discovering the serum

As seen in the press

Sharper oval

I'd been looking for a serum that lived up to its promises for years. In three weeks, my facial contour is more defined and my complexion brighter. The texture is a real pleasure; it's not sticky at all.

Fine lines softened

At 61, I thought I had tried everything. The fine lines around my eyes have visibly softened, and my skin looks plumper. The fact that it's made in Switzerland reassured me.

Immediate lifting effect

Immediate lift effect, that's not a slogan. In the morning, my skin feels tight and rested. I use it as a makeup base and the finish is perfect.
