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 of the serum 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 pH of the formulation is not ideal. The pH of this formula has been shown to be the most suitable pH to minimize degradation of Alpha Arbutin. 1 oz. Paraben-free; phthalate-free; silicone-free; sulfate-free Made in Canada
