Obagi’s serum works to brighten your skin tone, leaving behind a more luminous radiance that has a natural, healthy-looking glow. Formulated using 10% L-Ascorbic Acid, otherwise known as Vitamin C, the blend aims to encourage consistent colouring for a more even surface. It can improve the overall look of hyperpigmentation and dark spots, helping to lighten their appearance over time to make them less noticeable. This can create a more youthful illusion and may disguise the look of certain types of damage. Thanks to Arbutin, skin will seem lighter as it targets pigmentation that forms below skin, aiming to prevent future hyperpigmentation before it occurs.
