What Fitzpatrick skin type is often known to tan easily and rarely burns?

Type IV skin is characterized by its ability to tan easily and typically does not burn. This skin type usually has a medium to olive tone and is more melanin-rich compared to lighter skin types, which contributes to its ability to tan well in response to sun exposure. People with Type IV skin often have a low sensitivity to UV radiation, allowing them to develop a tan with minimal risk of burning.

In contrast, Type I is very fair and tends to burn easily without tanning. Type III has a fair to medium complexion and can tan but may also experience burns, especially with excessive sun exposure. Type V skin has a darker tone and can tan well, but it is more frequently associated with skin tones that are representative of individuals from Mediterranean and some Middle Eastern backgrounds, which can vary in sensitivity. Therefore, Type IV remains the fitting answer as it effectively describes skin that tans with ease and has a lower incidence of sunburn.
