At some time during your foundation training you would have come across ‘The Fitzpatrick scale’.
A numerical classification theory for human skin colour.
In 1975 a Harvard Dermatologist named Thomas B. Fitzpatrick developed a method of how to estimate different skin types response to Ultraviolet (UV) light.
Originally it was based on skin and eye colour, but this was crude and proved misleading, it was later developed and altered to be based on the patient’s reports of how their skin responds to the sun. The Fitzpatrick scale remains a recognized tool for dermatological research into human skin pigmentation.
It is a fundamental tool for technicians to evaluate a client’s skin tone and how it will interact with pigment selection.
We teach all our students The Fitzpatrick Scale.
