01
What it is
“Peptides” does not identify a single ingredient: it groups different molecules with distinct sequences and cosmetic purposes. Always read the INCI and information for the specific formula.
02
Its role in a formula
They may feature in formulas targeting firmness, texture or visible lines. They do not all work in the same way or interchangeably, and stability within the product is essential.
03
How to use it
Prioritise a complete, well-preserved formula suited to your skin type. Consistency and daily sun protection usually add more value than layering many products.
