My skin actually glows.
I've been using it every morning for about six weeks and my skin tone looks noticeably brighter and more even. Makeup goes on smoother too.

Some days your skin looks tired before you feel tired. Tone looks uneven. Radiance disappears. Your complexion just looks a little flatter than you want it to.
Vitamin C Renewal Serum gives dullness one dedicated daily step — designed to support brighter, smoother and more radiant-looking skin.
Dullness · Tone · Radiance · Texture
It’s the complexion that looks a little flat in the morning. The uneven-looking tone you notice without makeup. The feeling that your skin has lost some of the brightness it used to have.
You don’t need to change your face. You just want your skin to look awake again. That’s where this serum comes in.

Vitamin C Renewal Serum
Brighter · Fresher · More radiant-looking
Most people reach for vitamin C for one obvious reason: brighter-looking skin. PEPTYD built beyond that.
Vitamin C targets the appearance of dullness and uneven-looking tone, while GHK-Cu brings peptide-powered support for smoother, healthier-looking skin.

Brighter skin + more than brightening
The reason to believe
You came for brighter-looking skin. Here’s what’s behind the formula.
Stabilized Vitamin C
A stabilized vitamin C derivative used in skincare to provide antioxidant support and promote a brighter, more even-looking complexion.
Copper Tripeptide-1 (GHK-Cu)
A copper-binding peptide used in skincare to support natural renewal processes and healthier-looking, resilient skin.
Matrixyl 3000 Peptide Complex
A signal peptide complex selected to support smoother, more resilient-looking skin.
Niacinamide
Supports the appearance of smoother, more even-looking skin while helping maintain the moisture barrier.
Hyaluronic Acid
Helps attract and retain moisture for hydrated, plumper-feeling skin.
Pure vitamin C is famously difficult to keep stable in a bottle. This formula is built around a stabilized vitamin C derivative instead — the kind used widely in cosmetic skincare for antioxidant support and for brighter, more even-looking skin.
It also sits comfortably in a formula alongside peptides, which is what lets one lightweight daily serum work on brightness and skin quality at the same time.
This is not a claim that one form of vitamin C outperforms another. It is simply the form chosen for this formula and this routine.
Cleanse
Begin with clean, dry skin.
Apply Vitamin C Renewal Serum
Press a thin layer across the face and neck with your fingertips, avoiding direct contact with the eyes.
Moisturize
Follow with your preferred moisturizer to seal the routine in.
SPF — morning
Finish daytime routines with a broad-spectrum sunscreen.
Morning or evening. One step, every day.
When skin starts looking dull, it’s easy to add product after product trying to bring the radiance back. PEPTYD takes a simpler approach.
Give brightness one dedicated serum. Then moisturize. Then get on with your day.
