What scale is used to classify skin types in reaction to sun exposure?

The Fitzpatrick scale is specifically designed to classify skin types based on their response to sun exposure, taking into account the skin's tendency to burn or tan. Developed by Dr. Thomas Fitzpatrick in 1975, this scale categorizes individuals into six different types, ranging from Type I, which has a very fair complexion and always burns, to Type VI, which has deeply pigmented skin that never burns. This classification system is extensively used in dermatology and skincare to assess the risks associated with UV exposure and to personalize sun protection and treatment recommendations.

The other options, while related to skin characteristics, do not specifically focus on the reaction to sun exposure in the same way. The dermatological scale is more general and may not directly address sun response. The skin type index and melanin index also provide insights into skin properties but lack the focused context of sun exposure classifications that the Fitzpatrick scale offers.
