Peptides 5% Smoothing Booster

I’ve been using this booster for three weeks now, and my forehead lines actually look softer—the naturally fermented peptides are a big reason I trusted it, since most serums are full of synthetic stuff. It layers well under my moisturizer, and a little goes a long way, so the bottle should last me

The texture sinks in fast with no sticky film, and I love that the peptides are fermented rather than synthetic — feels cleaner on my skin. My forehead lines look softer by week three, and it layers perfectly under my moisturizer.

I was skeptical about another peptide serum, but the fact that these are naturally fermented and COSMOS certified sold me. After three weeks, my forehead lines look softer and my skin feels firmer without any greasy residue. This is the first booster I've actually finished before it expired.
