Now available as a 10mL trial size — this powerful combination of retinol and trichloroacetic acid (TCA) will bring about the change you are looking for in your complexion. Try our most comprehensive single anti-aging serum before committing to the full bottle. Combines the anti-aging benefits of retinol with the skin resurfacing ability of TCA to give visible signs of rejuvenated skin tone and texture within weeks of use. There is no better and more studied anti-aging ingredient than retinol. Contains TCA, a chemical peel ingredient rarely found in daily skincare products, that encourages resurfacing of the skin. Retinol prevents collagen breakdown and stimulates new collagen, which softens fine lines, refines pores, and provides for a more youthful appearance overall. Lightens uneven skin tone and pigmentation brought about by sun damage, hormonal changes, or acne scarring. Retinol addresses ALL the causes of acne: stops excess sebum production, speeds up growth of skin around pores to keep them clear, and helps skin adjust to hormonal fluctuations. Love it?
