What it is: A water-based brightening serum specifically designed to target uneven skin tone and visibly improve pigmentation. What it does: The formula combines a high concentration of purified alpha arbutin, a well-known skin-brightening ingredient, with hyaluronic acid. Purified alpha-arbutin works to target dark spots and uneven skin tone. Meanwhile, hyaluronic acid helps to support product absorption into the skin. How to use: Apply a few drops to the face in the morning and evening. Use sun protection during the day. If irritation occurs, rinse off, cease use and consult a physician. Use only as directed on unbroken skin. Patch testing prior to use is advised.Note: Alpha Arbutin is extremely sensitive to degradation in the presence of water if the p H of the formulation is not ideal. The p H of this formula has been shown to be the most suitable p H to minimize degradation of Alpha Arbutin. 1 oz. Paraben-free; phthalate-free; silicone-free; sulfate-free Made in Canada
