While the causes of acne have been attributed to a number of factors, from stress to diet to hormones, new research reveals a correlation between smoking and comedonal adult acne in women.

The study, published in the Journal of American Academy of Dermatology, reports that 226 women with acne, ages 25 to 50, were assessed by dermatologists. They found that 85 percent of the patients were classified as having comedonal post-adolescent acne, and of those 192 women, 72.9 percent were smokers.

“The findings will affect our treatments, and we will need more products with Vitamin A and alpha and beta hydroxyl-acids to clear the skin along with exfoliating products, as well as more education for the public at large about the damaging effects smoking can have on the body’s largest organ, the skin,” Dr Marcy Street, a dermatologist in East Lansing, Michigan, told StyleList.com.

Women who suffer from adult acne should consider using products to help treat their condition. Peter Thomas Roth Beta Hydroxy Acid 2% Acne Wash is an oil-free formula that gently exfoliates the entire face, while Exuviance Blemish Treatment Gel, which contains Vitamin A and salicylic acid, can be used on specific problem areas.
