Dermatologists think of skin types as a description of how likely a person is to get a sunburn. Skin type 1 people burn very easily in the sun while skin type 5 people tan extremely easily and burn very rarely. The lower number skin types have an increased risk of skin cancer and need to be extra cautious with sun protection.
You may also be curious about your skin tone. Within all of the skin types, people may have cooler or warmer skin tones. If you can see lots of pink flushing in your skin or your veins appear blue under the surface of your skin, your skin tone is likely cooler. If your skin has more yellow undertones, with less pink flushing and greenish veins, then you have a warmer skin tone. You can also have a neutral skin tone, which lies somewhere in the middle.
