Which skin type is most at risk for burning during tanning?

Skin type I is characterized by very fair skin, often accompanied by light hair and eye color, and it typically does not tan at all. This skin type is notably sensitive to UV exposure and is highly prone to sunburn. Individuals with skin type I tend to freckle easily and can burn after minimal exposure to the sun or tanning beds.

In contrast, skin types II and III have slightly more melanin, which provides some level of protection. While they can still experience burning, especially with prolonged exposure, their risk is lower compared to skin type I. Skin type IV, with a medium tan and a greater ability to tan without burning, is even less susceptible to burns. Therefore, skin type I is indeed the most at risk for burning during tanning, making it the correct choice in identifying the skin type that should take extra precautions when exposed to UV light.
