Hydroquinone USP 4 Skin Bleaching Cream is indeed a well-known topical treatment for conditions like melasma, freckles, and age spots. It works by reducing melanin production in the skin, which gradually lightens dark patches. However, it’s always recommended to use it under medical supervision to avoid side effects. Similarly, for people living in Dubai who may require professional medical assistance at home, services like Doctor on Call Dubai can be extremely helpful.
