PIGMENTATION REDUCING COMBO The Collection incorporates Azelaic Acid, Alpha Arbutin, and Vitamin C formulas to brighten and improve the appearance of uneven skin tone. These three ingredients can be layered together, or separately, so you can find the best options for your regimen. The Azelaic Acid Suspension 10% is a gentle, cream-like formula that brightens skin tone and visibly improves skin texture due to a high concentration of azelaic acid—a natural and effective antioxidant found in grains. The Alpha Arbutin 2% + HA is a water-based serum containing a high concentration of Alpha Arbutin to target the appearance of uneven skin tone. Vitamin C Suspension 23% in HA Spheres uses direct vitamin C and hyaluronic acid to help visibly reduce signs of aging by brightening and balancing uneven skin tone. This water-free formula provides 23% pure L-Ascorbic Acid which remains completely stable due to the absence of water. What’s more, this water-free formula is supported with spheres of hyaluronic acid for added hydration.
