👉 Melasma is a skin condition that occurs when the skin becomes inflamed, red, and itchy due to an overproduction of sebum. It's characterized by patches of white or yellow skin, often on the face, neck, chest, and back, causing sensitivity and irritation. Melasina can be caused by various factors such as hormonal changes, genetics, stress, pollution, and certain medications. Treatment options include topical creams, ointments, and prescription drugs for inflammation relief.
