The Fitzpatrick skin type is a way to classify skin by its reaction to exposure to sunlight based on the amount of melanin pigment in the skin. The Fitzpatrick skin type classification has six categories, ranging from skin that always burns and never tans (Fitzpatrick skin type I) to skin that never burns and always tans darkly (Fitzpatrick skin type VI).

When buying products for Fitzpatrick skin type II, which burns easily and tans poorly, some ingredients to look for include retinoic acid, vitamin C, and hyaluronic acid. However, it is important to note that the Fitzpatrick skin type is a constitutional characteristic present at birth and that it may not accurately reflect an individuals risk of developing skin cancer.

Overall, the Fitzpatrick skin type is a useful tool for dermatologists to determine the appropriate settings for laser therapy. It is also helpful for individuals to understand their skin type and choose appropriate skincare products and sun protection measures.
