Anti-aging care for biological age, not chronological age.

NUANCE is based on the premise that skin age is not a number of years—it's a complex sum of genetics, lifestyle, nutrition, environment, and skincare. The line works on the biological age of the skin: it reduces inflammation and MMP activity, neutralizes free radicals, and supports nine key vitality processes (collagen and elastin synthesis, natural exfoliation, microbiota balance, barrier function, firmness, nourishment, hydration, cell renewal, and precursor delivery).

The signature of the line is Melatonin Liposomal—patented grape-derived melatonin in liposomal form. Applied topically, it acts as a very powerful antioxidant (comparable to Trolox even at a concentration of 1.25%), reduces "crow's feet," and supports barrier renewal. It is supported by Retinol HPR (Hydroxypinacolone Retinoate), Tri-Luronic Acid, biomimetic collagen, Phyto-Ceramide Complex, Spirulina, Marine Moist, and Aquaderm.
