Hydroquinone has been used for over 25 years in the United States for treatment of hyperpigmentation. Apply a thin film twice daily to the area in need of bleaching or as directed by a physician. The products should be rubbed into the skin well. Make-up can be applied after the treated area has dried. When applied as directed, the sunscreens in Glyquin provide necessary sun protection during skin bleaching therapy.
Most dark colorations begin to lighten after four weeks of treatment.
This lightening, however, may take longer. After desired bleaching. use only as needed to maintain results. After clearing and during maintenance therapy, sun exposure should be avoided on bleached skin by application of a sunscreen or by wearing protective clothing to prevent darkening from recurring. Test for skin sensitivity before using by applying the product to an unbroken patch of skin. If no redness or itching occurs within 24 hours, begin treatment.
