How to Use
Blue Peptide Cica Serum

Using the built-in spatula, blend the cica oil gel and the blue peptide water gel in circular motions.

Scoop out an adequate amount and gently roll it over the skin to blend both layers.

As it melts into a serum-like texture, pat lightly onto skin to help it absorb.

The two layers separate naturally. Blend them with the built-in spatula before use.

FAQ

Still wondering?
Here’s what you might want to know.

Retinol has some of the most established evidence in topical anti-aging skincare, but it can be irritating for some skin types. Blue Peptide, or GHK-Cu, offers a peptide-based approach focused on firmness and elasticity, with a molecular size far smaller than native collagen or PDRN. Collagen is commonly used for surface hydration and plumping, while topical PDRN is an emerging category whose performance depends strongly on molecular size and formulation.
