How Tanning Occurs? The sun's light rays consist of two kinds of ultraviolet emission that access your sensitive skin: UVA and UVB. UVB emission burns the superior cellular levels of skin (the epidermis), leading to sunburns.

UVA emission is exactly what can make individuals tan. UVA light rays go through to the lower cellular levels of the epidermis, in which they result in tissues known as melanocytes (pronounced : mel-an-oh-sites) to generate melanin. Melanin is the dark brown pigment which causes tanning.

Melanin is the body's method of shielding pores and skin from burning up. Darker-skinned individuals tan more deeply than lighter-skinned individuals mainly because their melanocytes generate a lot more melanin. However simply because an individual doesn't burn does not necessarily mean that he or she can be safeguarded against skin cancer and other issues.
