How It Works

Potent Retinol Serum works at a cellular level to accelerate skin renewal and restore a smoother, more even complexion. Encapsulated 0.5% Retinol penetrates the skin over time, normalising cell turnover, repairing DNA damage, normalising all cellular processes and stimulating collagen and elastin production. This action reduces fine lines, refines texture, unclogs pores and diminishes hyperpigmentation. Supporting actives including O’s V8 Peptide Complex, Niacinamide, Hyaluronic Acid, Vitamin E and SymRelief enhance the formula to hydrate, calm inflammation and protect against oxidative stress, leaving skin visibly renewed, refined and healthier with continued use.
