Our skin contains the history of human life and death. Our skin has undergone various changes to maintain survival. The color of our skin and hair is determined by melanin. Eumelanin not only makes hair black, brown, and blonde but also produces darker skin tones. Pheomelanin produces red hair and lighter skin tones.
