|The Fitzpatrick Skintype Scale|
Skin type is classified according to its tolerance of sunlight, according to The Fitzpatrick Scale.
This scale was developed back in 1975 by a then Harvard Medical School dermatologist, Thomas Fitzpatrick.
This scale is used in the beauty world by aesthetians and beauticians to determine how someone will react to facial treatments.
||Skin Burn/Tan Notes

|Very fair (red/blonde)
|Always burns, never tans
||Very fair (red/blonde)
||Usually burns, tans only with difficulty
(light brown, blonde, red)
||Burns first then tans gradually to light brown
|Light tan brown
(typical Mediterranean caucasian skin)
||Rarely burns, tans with ease
||Medium or dark
||Very rarely burns, usually tans
||Dark brown or black
||Any colour but usually brown
||Never burns, tans very easily
That's it. This is what is used to classify skin according to this scale. For example, I am between a III and a IV on this scale. Knowing what your skin type is can help you yourself (aside from any aesthetian) figure out what works for your skin in terms of skincare products.
