As skin ages, it loses its natural ability to repair and regenerate itself. Collagen production and skin cell turnover slow down with aging. The result is thinner skin that is prone to sagging and wrinkling. The Olay Regenerist collection contains a groundbreaking aminopeptide complex, which is an effective weapon in the battle against the visible signs of aging. This powerful aminopeptide compound stimulates skin cell renewal, producing smoother, firmer skin. The Olay Regenerist range has been clinically proven to produce measurable results, revealing younger looking skin after only two weeks.
