Hyaluronic Acid

Immediate hydration support and visible plumping. The Mirror Test™ molecule.

In cosmetic formulations, dual- or multi-molecular weight HA provides immediate hydration support and visible plumping on application. One of the key molecules behind the Hot Peps Mirror Test™ philosophy — what your skin shows the moment you look up, not just over time.
