NeoStrata HQ Skin Lightening Gel is formulated with 10% Polyhydroxy Acids that help remove hyperpigmentation by gently exfoliating dark spots and enhancing cell turnover. Antioxidant chelators help to capture pigment promoting metals in the skin while Hydroquinone (2%) helps lighten discolorations. Added Kojic Acid (3%) and licorice extract promote an even complexion. NeoStrata HQ Skin Lightening Gel will effectively lighten skin discolorations such as freckles, age spots and hyperpigmentation that may occur from pregnancy or from the use of oral contraceptives. Directions: Apply a thin layer on affected area twice daily or as directed by a doctor. If no improvement is seen after 3 months treatment, discontinue use. Lightening effect may not be noticeable when used on very dark skin. Limit sun exposure during and after use to prevent darkening from recurring. Use a sunblocking agent or protective clothing.Net Weight: 1 oz. Ingredients: Active Ingredients: Hydroquinone 2%.
