This copper peptide face serum from TOSOWOONG is formulated with GHK-Cu (copper tripeptide) along with a 12 multi-peptide complex. The blend is designed to support skin firmness, elasticity, and hydration while addressing the appearance of fine lines. As a Korean skincare product, the serum focuses on a balanced formula that aims to maintain the skin's natural barrier and overall texture.

The inclusion of copper tripeptide, known for its role in promoting collagen synthesis, works alongside other peptides to encourage a smoother, more resilient complexion. The lightweight, watery consistency absorbs quickly without leaving a sticky residue, making it suitable for layering under moisturizers or sunscreen. It is gentle enough for daily use on most skin types, including sensitive and combination skin.

Key aspects of this serum include its 33ml / 1.11 fl.oz. packaging and the absence of harsh additives, with an emphasis on delivering active ingredients in a stable format. Regular application may help improve skin density and reduce the visibility of fine lines over time. The formulation also provides lasting hydration, which contributes to a plumped and refreshed appearance.

This product is positioned for those seeking a multi-functional anti-aging serum with a peptide-focused approach. It aligns with the Korean skincare philosophy of gradual, consistent care without aggressive ingredients. The result is a straightforward serum that supports the skin’s natural renewal process while maintaining comfort and balance.
