Very much so. The big thing is moisturizing which black people do waaay more of than whites, and especially beneficial if it's an SPF moisturizer. Sunscreen and low UV exposure in general, as well not smoking or drinking are also huge factors, but are much less racially skewed. Stress and illness are also pretty big factors, but tend to be racially skewed against blacks for socioeconomic reasons.
