Clinical studies and natural methods have both demonstrated the efficacy of THALIA LIGHTENING CLEANSING FOAM 150ML in combating skin spots. Alpha-Arbutin, a naturally occurring skin lightening agent, is made from the leaves of fruits like cranberries, pear, and uva ursi. It is used to treat hyperpigmentation, or dark circles and skin spots. Alpha Arbutin is a cosmetic product that reduces the appearance of age spots, sun spots, dark circles under the eyes, and acne scars. It smoothes and brightens the skin by inhibiting the tyrosinase enzyme, which is necessary for the synthesis of melanin during the process of skin regeneration. DIRECTIONS: Apply Thalia Brightening Skin Cleansing Foam to damp skin and thoroughly rinse with water. For best results, use in conjunction with other Thalia Alpha Arbutin Series products.
