Acne is a dermatosis that affects 50-95% of adolescents aged 12-18 years and has adverse social and emotional effects on this age group. In addition, an increasing number of adolescents are switching to a vegan diet. However, no studies have yet been conducted to evaluate whether following this type of diet has a positive or negative effect on acne.

In order to evaluate the relationship between veganism and acne, Dr Ramon Grimalt, dermatologist and lecturer in the Bachelor’s Degree in Medicine, and fifth year student Paula Sánchez, have conducted a study in which they have reviewed the currently available literature on acne and nutrition. Entitled “The Influence of Veganism on Acne,” the paper was recently published in the Journal of Dermatology Research.

After analysing the scientific literature published in the Cochrane Library and the PubMed database, “studies showed that milk and milk products, as well as diets with a high glycaemic index, have a negative impact on acne,” explain the authors of the study. “In addition, some studies suggest that a low consumption of vegetables can make acne worse,” they add.

Paula Sánchez, author along with Dr Grimalt, spoke about the experience of being a medical student, conducting a study of these characteristics and then seeing it published. She explained that “this article has taken a lot of effort and dedication, but it has allowed me to learn numerous communication skills within the scientific world, as well as experiencing the whole process behind the publication of an article and the excitement of seeing it published”.
