The Fitzpatrick Skin Type (FST) system, introduced in 1975, is a method for classifying an individual’s skin color and its response to UV light, mainly to predict the risk of sunburn, skin cancer, and to guide the dosage for UV and laser treatments. The scale ranges from Type I, which always burns and never tans, to Type VI, which never burns and is deeply pigmented. While it has been widely used in dermatology for various purposes, including assessing the risk for skin cancer and determining the settings for laser hair removal, the FST system has its limitations.
One significant limitation is its inadequacy in describing the skin of color accurately. Initially, it lacked classifications for darker skin tones, and although it was later expanded, it still fails to capture the diverse range of skin colors in People of Color and those of mixed race. This has led to healthcare disparities and a lack of accurate risk education for skin cancer among these populations.
Moreover, the FST system is criticized for its subjective language and reliance on the individual’s perception of their skin’s reaction to the sun, which can be unreliable. Terms like "tan" and "burn" may not accurately describe the experience of those with darker skin tones. Some studies have shown that individuals with darker skin, who are traditionally considered less susceptible to sunburn and skin cancer, still report effects from sun exposure and require appropriate sun protection measures.
There are calls for alternative or modified classification systems that more accurately assess photosensitivity and skin cancer risk across diverse skin types. Despite its limitations, the FSP remains a commonly used tool in dermatology. It highlights the importance of personalized skincare and protection for all skin types, emphasizing that regardless of FSP, individuals should practice sun safety to reduce the risk of skin damage and cancer.
