Peptides Skincare Products

What Do Peptides Do?

Peptides are short chains of amino acids - the building blocks of proteins like collagen and elastin that keep skin firm and bouncy. Applied topically, they signal the skin to support its own collagen production, helping to improve the look of firmness, fine lines and elasticity over time. They're a gentle, well-tolerated way to target the signs of ageing, making them a smart addition to almost any routine.

How to Use Peptides

Peptide serums and creams go on after cleansing, and because they're gentle they can be used morning and night. The Medicube PDRN Pink Peptide Serum combines peptides with PDRN for a firming, radiance-boosting treatment. Peptides pair well with hyaluronic acid and niacinamide, and they're a good alternative for anyone whose skin finds retinol too much.
