Diet, hygiene, and stress are the three external factors that can influence the appearance of acne, according to a study presented at the Congress of the European Academy of Dermatology in Madrid.
Gathered in Madrid for their 28th Congress, physicians from the European Academy of Dermatology presented a study indicating three factors mainly implicated in acne. The dermatologists evaluated exposure to different factors aggravating acne in more than 6,700 participants from six countries in North America, South America and Europe. According to the results, poor eating habits, increased stress and poor skin care are the factors most frequently associated with acne.
Beware of dairy products and sugar
Regarding diet, the study shows that significantly more people with acne (48.2%) consume dairy products on a daily basis than those who do not (38.8%). The difference is also statistically significant for fruit juices and soft drinks (35.6% vs. 31%), sweets and chocolate (37% vs. 27.8%), and candy (29.7% vs. 19.1%).
Exposure to pollution or stress was also more common in acne subjects than in control participants.
Acne is estimated to affect one in 10 people worldwide, making it the eighth most common disease. Recently it has been reported that acne also affects 40% of adult women.
