How It Works

At 12% Niacinamide, it strengthens the skin’s natural defences (skin immune system), regulates sebum and reduces redness for a clearer, calmer, more balanced complexion. Vitamin C and targeted brightening peptides help fade and prevent further hyperpigmentation and even skin tone from forming, while collagen-stimulating tripeptides support elastin and structural integrity, softening fine lines and improving firmness. Supporting actives work synergistically to enhance barrier function, calm inflammation and boost overall radiance, leaving skin smoother, resilient and visibly rejuvenated.
