What type of skin is less likely to tan and more prone to burning?

Skin type I, often referred to as very fair skin, is characterized by a lack of melanin, which means it has very little natural protection against UV radiation. This type of skin typically has light-colored eyes (blue or green) and hair (blond or red), and it tends to sunburn easily and quickly without tanning.

Individuals with skin type I are hypersensitive to sunlight, showing signs of burning almost immediately after sun exposure, while tanning is rare. As a result, those with this skin type must take extra precautions when it comes to sun exposure or tanning to avoid serious skin damage.

In contrast, skin types II and III have slightly more pigmentation, which provides a bit more protection and allows them to tan to some degree while also being prone to burning. Skin type IV has more melanin, making it less susceptible to burning and more likely to tan effectively.
