Melanin is the natural pigment responsible for determining skin color and helping protect against ultraviolet radiation. When melanin production increases, the skin gradually darkens, creating a tanned appearance. Therefore, methods that stimulate this process aim to enhance the body’s natural response rather than relying entirely on sunlight. As a result, individuals may achieve a more even and controlled tan over time. Visit : https://www.trutan.net/tanning-injections-how-they-work/
