Acne is a chronic inflammatory disease of the pilosebaceous unit, and its etiology is complex and multifactorial. The role of the diet in its pathogenesis is still debated. The purpose of this study was to assess the association between MD and IGF-1 in acne patients and, as secondary objective, the role of systemic treatment on IGF-1 serum levels, in accordance with the patients’ diet. This study included 35 patients aged 14-30 years affected by acne and treated in line with the EDF guidelines. Patients were divided into 2 groups based on a questionnaire score assessing the adherence to the Mediterranean diet: the Mediterranean Group (score ≥6) and the Western Group (score< 5). IGF-1 serum levels were measured in all patients before and after treatment and then compared to healthy population. IGF-1 levels were higher in patients than in controls and in the Western group than in the Mediterranean group. We speculate that the Mediterranean diet can have a protective role in the pathogenesis of acne by acting on the systemic route of IGF-1.
