Melanin is your skin's natural protection system—produced by melanocytes in response to UV radiation, it absorbs and disperses ultraviolet rays to prevent DNA damage. Learn about the two types (eumelanin for brown/black protection, pheomelanin for fair/red skin with less UV defence), why tanning is a stress response not healthy skin, and how inflammation, hormones, heat, and visible light also trigger pigmentation. Discover why no skin type is immune to sun damage and how to build healthy sun habits with SPF, antioxidants, and balanced exposure.
