Why are people with non-white skin more likely to get a tan?

People with non-white skin are more likely to get a tan, mainly because their skin contains more melanin. Melanin is a natural pigment, which can form a protective film on the skin surface to help resist the damage of ultraviolet rays. People with fair skin usually have less melanin content, so they are more vulnerable to ultraviolet rays. When they are injured by ultraviolet rays, their skin is more prone to adverse reactions such as spots.

In addition, tanning is also related to a person's genes and race. Different races and genes have different response and repair abilities when exposed to ultraviolet rays. For example, when some Asians are exposed to ultraviolet rays, their skin may appear more sunburn and blackening, while whites are relatively less likely to get a tan.

Therefore, for people with non-white skin, it is easier to get a tan because they contain more melanin. However, regardless of skin color, we should pay attention to sun protection to avoid long-term exposure to ultraviolet rays and protect skin health.
