Effect Of Warm Climate In Acne

In addition to the physiological differences between Black, Hispanic (or southern European), and White skin, there are several demographic differences that surprisingly have a significant impact on acne.

The first is that the Black population in the United States-and, to a lesser extent, the Hispanic populations tend to be concentrated in areas where the climate is hotter and more humid. As you know, in these warmer climes, one tends to perspire more than in cooler areas. The act of sweating actually aggravates or increases the likelihood of acne as the excess moisture swells the skin around the pores, which blocks them, causing more acne. In other words, while Black skin is more prone to acne anyhow, it is also true that demographically Blacks often reside in “acne-genic” locations-that is, the areas of the country with high temperatures and humidity. This compounds their acne problem.

The second sociological factor is that Black men and Black women often use oil-containing hair products. These products are usually used to give added sheen and to help manageability. Since any oily product applied to the hair is likely to spread to adjacent areas, especially the forehead, neck, and upper shoulders, these hair preparations often aggravate acne.

Black women (and very occasionally Black men) often straighten their hair, a procedure that generally involves the use of harsh chemicals. Also, certain curling techniques involve the use of chemicals heat. We have no proof, but we suspect that some of these chemicals may slightly damage and dry the skin near the scalp, making it more prone to acne invasions.

Finally, more Blacks and Hispanics in the United States smoke than do Whites. And, there is no doubt that smoking, in addition to all its other negatives, aggravates acne.
