– EN Fitness & Wellbeing – An unhealthy diet is one of the most significant factors associated with acne, according to a new study.
New research conducted on behalf of skincare company Vichy Laboratories evaluated the exposure to different factors on acne, a skin condition that affects up to one in 10 people globally, in more than 6,700 participants across six countries in North America, South America, and Europe.
The research, the first-ever study to analyse both internal and external factors in relation to the skin condition, showed that significantly more individuals with acne consume dairy products on a daily basis compared to individuals who did not, with a difference of 48.2 per cent to 38.8 per cent.
The difference was also statistically significant for soda juices or syrups, pastries, and chocolate, with 37 per cent of acne sufferers eating them compared to 27.8 per cent without acne, and sweets, with 29.7 per cent compared to 19.1 per cent.
Researchers also found that 61.9 per cent of individuals with acne nibbled on food frequently and regularly compared to 43.2 per cent of control participants.
In addition, exposure to pollution or stress were also more frequently observed in participants with acne compared to control participants, and harsh skincare practices were more common in acne sufferers.
However, tobacco, which had previously been identified as a possible acne trigger, was not shown to have an influence.
“Acne is one of the most common reasons why people with skin issues contact a dermatologist. Its severity and response to treatment may be influenced by internal and external factors, which we call the exposome,” said lead researcher Professor Brigitte Dreno. “For the first time, this study allows us to identify the most important exposome factors relating to acne from patient questioning prior to any treatment prescription.”
The research was presented at the 28th EADV Congress in Madrid, Spain over the weekend.
