What scale is used to classify skin types based on UV light response?

The Fitzpatrick scale is the recognized classification system used for categorizing skin types based on how skin reacts to ultraviolet (UV) light exposure. Developed by Dr. Thomas Fitzpatrick in 1975, this scale ranges from Type I to Type VI, helping practitioners and researchers understand skin's susceptibility to sunburn, tanning ability, and risk of skin cancer.

This classification is critical for various applications in dermatology, including selecting appropriate treatments for photodamage and estimating the effectiveness of interventions such as laser therapies. Each type on the Fitzpatrick scale reflects distinct characteristics related to melanin production and overall skin resilience, which informs how individuals should protect their skin from UV exposure and how they might respond to various cosmetic and medical treatments.

Other scales mentioned, such as the Graham, Hannibal, and Jacobs scales, do not pertain to skin type classification related to UV response and are not used in this context.
