Is tanning really healthy? Thank you, everyone.

Tanning is not healthy for the skin! Suntan is the skin's defense against sun damage. When the human body is irradiated by ultraviolet rays, it will form more melanin in the basal layer to protect the skin from ultraviolet rays, which is also a self-protection function of the skin. Although skin blackening is a kind of protection, the SPF of this protection is only 2, which is not very helpful. Any degree of tanning will increase the risk of skin cancer and cause skin aging and wrinkles, so any form of tanning is unhealthy.
