The Fitzpatrick skin type scale is a way of classifying people's skin color. It helps scientists, doctors and makeup artists to determine the best products, medications, and treatments for each person. On the scale, skin colors range from very light (Type 1) to very dark (Type 6). Each type is given a letter, from Type A (very light) to Type F (very dark). Knowing your Fitzpatrick skin type can help you choose the best skincare and makeup for you, and help you stay safe in the sun.
