FactorFive Daily Regenerative Serum is an advanced treatment serum formulated with human stem cell derived growth factors, polypeptide complexes, and cytokines that help with anti-aging skin care. Your skin cells are constantly turning over and undergoing repair. This remodeling, correcting, and regenerating requires multiple cellular processes to work. That’s where FactorFive comes in. Our scientists carefully culture human stem cells and then capture their potent factors — all in an effort to help your skin replace and boost the factors that decrease with age, helping prevent and fight the visible signs of aging.
