What does the Fitzpatrick Scale measure?

The Fitzpatrick Scale is a classification system that measures skin types based on their sensitivity to UV radiation and their reaction to sun exposure. Primarily, it categorizes skin tones into six different types, ranging from very fair to deep brown, and assesses how each skin type responds to sunlight. This includes their likelihood of tanning or burning when exposed to UV rays. Understanding a client's Fitzpatrick type is crucial for estheticians, as it directly informs how to approach sun protection education, skincare treatments, and chemical peels to ensure safety and efficacy.

In contrast, skin moisture levels, sensitivity to temperature, and skin elasticity are related to different skin attributes and concerns, but do not specifically address the skin’s reaction to UV exposure or its classification based on sun sensitivity. These other measures do not contribute to the fundamental purpose of the Fitzpatrick Scale, reinforcing that option C is the most relevant and accurate choice.
