Blue Youth Activating Drop

A featherlight serum from Klairs that leans on two EGF peptides, sh-Polypeptide-1 alongside sh-Oligopeptide-1, with adenosine in support, to soften how fine lines read and leave the surface looking smoother. Guaiazulene, butylene glycol and glycerin bring water back and keep the finish calm rather than heavy. Blueberry fruit extract covers the antioxidant angle against pollution and daily stress; it sinks in fast and layers under whatever follows.
