COSRX The 6 Peptide Skin Booster Serum

COSRX The 6 Peptide Skin Booster Serum is a lightweight peptide serum used right after toner to firm, smooth and hydrate the skin and help the rest of your routine absorb. Six peptides support firmness and elasticity, while hyaluronic acid and amino acids hydrate. The watery serum spreads easily, so this big 150ml bottle lasts for months of twice-daily use. Peptides are gentle and suit almost every skin type, which makes this an easy first anti-ageing step. Best for: early fine lines, loss of bounce, dehydrated skin and anyone starting slow-ageing skincare.

Key ingredients: 6 peptides, hyaluronic acid, amino acids.

After toner, apply 2-3 pumps to the face and pat in. Follow with your serum and moisturiser. Morning and night.
