01
What it is
Hyaluronic acid helps attract and retain water at the skin surface. Cosmetic formulas use different molecular weights and forms of the molecule to create distinct textures and performance profiles.
02
Its role in a formula
In a well-built routine, it supplies hydration without replacing the moisturiser that helps limit water loss. It is particularly useful when skin feels tight, dull or dehydrated.
03
How to use it
Apply to clean skin and follow with a moisturiser. During the day, always finish with sun protection. Adjust the amount if the climate or the rest of the routine makes the formula feel tacky.
