    Fitzpatrick Scale

    Definition

    A numerical classification (I–VI) that describes how different skin tones respond to UV light, used by laser providers to select safe settings and predict results.

    The Fitzpatrick Scale was developed in 1975 to classify skin types I through VI — from very fair skin that always burns (I) to deeply pigmented skin that never burns (VI). It's the standard tool laser and IPL providers use to choose safe energy settings, because more melanin means more risk of the laser targeting the skin itself rather than just the intended pigment or hair.

    ⚠️ ImportantAlways work with a provider whose technology is FDA-cleared for your Fitzpatrick type. Older lasers were not designed for skin types IV–VI.
