Reasons for Skin Darkening
This occurs when the skin produces excess melanin after inflammation or injury. Acne, pimples, rashes, burns, allergic reactions, insect bites, cuts, eczema, or cosmetic procedures can all leave behind dark marks once healed. Even mild inflammation can stimulate melanocytes, especially in individuals with sensitive or darker skin tones. Habits such as picking pimples, scratching the skin, or using abrasive scrubs increase inflammation and make pigmentation more persistent. Over time, repeated inflammation can make the skin appear darker overall.
