VC15 Serum
A truly even tone. Not just a glow.
A serum designed to address one of the issues that makes us look oldest in the mirror: uneven skin tone.
Pure vitamin C is effective, but it is also unstable. It oxidizes easily, turns orange, and is often formulated at a very acidic pH. This makes it more difficult to combine with other active ingredients and less tolerable for daily use.
In VC15 Serum, all vitamin C is stabilized. That is why the pH is adjusted to ~5.5, which is compatible with the skin and frequent use. This allows us to incorporate 2% tranexamic acid, the active ingredient of choice for reducing spots and marks.
- 15% stable vitamin C: radiance and antioxidant support.
-
2% tranexamic acid: evens out skin tone and improves dark spots and blemishes.
Unlike acid serums, which have usage restrictions, when you can use this product every day, the benefits build up over time: week by week, your skin looks more even-toned.
A 15% concentration of functional vitamin C falls squarely within the range known to promote collagen production, thereby helping to reduce the signs of sagging skin, such as fine lines and wrinkles.
Airless packaging and nitrogen-flushed packaging to preserve the product's properties as much as possible. 30 ml.

"The best vitamin C serum I've ever tried"
Dr. Paz Cerdá.

What it does (and what it doesn't).
What to expect:
- Quick improvement in brightness.
- Gradual lightening of brown marks (post-acne or post-irritation). Visible improvement usually begins within 4–8 weeks with consistent use.
- With melasma, improvements are slower: reduced contrast and smaller patches, with a more even skin tone. It requires consistency.
- Gradual softening of the color and edges of sunspots.
- Vitamin C is one of the most well-studied pro-collagen ingredients available. At a 15% concentration, it improves skin firmness and reduces wrinkles and fine lines.
The complete elimination of melasma and solar lentigines is usually beyond the scope of cosmetic products and requires dermatological treatment.
Use it with SPF 50
Vitamin C and tranexamic acid help even out skin tone, but the sun is the main cause of dark spots reappearing.
Without strong protection, the glow you wake up with each morning fades as soon as you step outside.
Recommended morning routine:
VC15 Serum + SPF 50.
This way, you help the serum work effectively, and the benefits really build up over time.
