Best Overall
The house's headline serum: a copper peptide for the look of firmness, carried in a plumping complex of hyaluronic acid, polyglutamic acid and the brand's own squalane.
The serum the house is known by, and the one bottle that shows the whole design: Copper Tripeptide-1 for the look of firmness, a Rapid Plumping Complex that makes skin look full on contact, and the sugarcane squalane base underneath. At 50 ml, fragrance free and EWG Verified on its listing, it is also the easiest Biossance purchase to justify. If the brand gets one chance on your shelf, this is the bottle that should take it.
Suits
Anyone who wants one serum that visibly plumps on contact and works on the look of firmness over time, and who values the largest serum bottle in this hub.
