Peptides

The building blocks for a resilient, bouncy complexion.

What it is

Peptides are short chains of amino acids that act as messengers for the skin. In K-beauty, they are often formulated in multi-peptide complexes to support the skin's natural moisture barrier and improve the look of firmness and elasticity.

Best forImproving the appearance of fine linesSupporting skin texture and bounceMaintaining a hydrated, plump look

How to use

Apply to clean, slightly damp skin as part of your serum step. Peptides are gentle and work well in both morning and evening routines, layering easily under heavier moisturizers.

Watch out

Do not layer high concentrations of direct acids, such as AHAs or BHAs, at the exact same time as copper peptides, as the low pH may impact the stability of the formula.
