Which skin types are more prone to burning than tanning?

Skin types I and II are characterized by their lighter pigmentation and lower amounts of melanin, which makes them more susceptible to sunburn. Individuals with these skin types typically have fair skin, light hair, and may have freckles. When exposed to UV radiation, their skin is less able to produce the protective pigment melanin effectively. Consequently, they tend to burn more easily compared to their ability to tan.

In contrast, skin types III and IV have more melanin, which affords them a greater level of protection against sunburn, allowing them to tan more easily and burn less frequently. Skin type V has even more melanin, leading to a strong natural defense against sunburn.

Thus, the classification of skin types I and II accurately highlights those that are more prone to burning than tanning due to their biological characteristics regarding melanin production and pigmentation.
