Firmness and renewal

DNA

DNA, the molecule that carries genetic information, purified for skincare, either whole or hydrolyzed into smaller fragments.

What it does: Used in toners and serums in firming and recovery routines, marketed for skin that looks firmer and bouncier.
How often: Morning and evening in ordinary serums and toners; Reedle Shot treatments are for evenings, with schedules that vary by strength, and the two-step hydrogel mask is occasional. Sun care needs morning application and daytime reapplication.
