Obagi-C System incorporates powerful skin brightening technologies in the form of Vitamin C (L-Ascorbic Acid), Arbutin, Glycolic Acid and Hyaluronic Acid and Vitamin E. This system penetrates the skin deeply to target early signs of photo-ageing. It helps to restore skin luminosity to regain a radiant, healthy glow. The typical Obagi-C System consumer would be those looking to address early signs of sun damage: fine lines, mild to moderate hyperpigmentation, superficial age spots, uneven skin tone, rough texture and those who want a simple, easy-to-use system. Can also be used after treatment with hydroquinone with a Dermatologist or medical practitioner to prevent future damage – use in conjunction with a high factor, broad-spectrum sunscreen.
