Skin Sciences第 38 / 100 题
A Fitzpatrick Type V client requests aggressive exfoliation to fade dark marks left by acne. What is the most important consideration?
a.Darker skin tolerates any strength of peel without risk
b.The service should be refused because darker skin cannot be exfoliated
c.Higher Fitzpatrick types are more prone to post-inflammatory hyperpigmentation, so treatment should begin conservatively with sun protection and gradual progression
d.Fitzpatrick type only predicts sunburn and has no bearing on exfoliation
解析
Melanocytes in higher Fitzpatrick types respond to inflammation by producing excess pigment, so aggressive treatment can darken the very marks the client wants to fade. A cautious protocol, gradual strength increases, and daily broad-spectrum sunscreen are the safe approach. Refusing entirely is unnecessary, and Fitzpatrick type is directly relevant to treatment aggressiveness, not just sunburn.
