Who doesn’t want fair, beautiful face? Everyone in the world is not blessed with beautiful face. Some have dark patches on the face; some have uneven skin color and some have blister on the face. Hydroquinone 4 is a skin lightener cream used in whitening the face and dark mark treatments. It decreases the creation of melanin in your skin, so it is great for fading hyper pigmentation, sun spots, acne marks, melasma and other skin discoloration issues.
