The aim of this study was to assess the relationship between the daily consumption of 50 g of chocolate with 85% cocoa content and the severity of acne lesions. Methods: The study involved 92 participants with acne who were divided into two groups, A (n = 51) and B (n = 41). In the first week, both groups had to follow an anti-inflammatory diet (AID), then for the next 4 weeks, group A continued on with the AID, and group B followed an AID with chocolate. After this time, group B started a 4-week AID without chocolate, and group A started a 4-week AID with chocolate. The severity of acne lesions was assessed using the Investigator&rsquo:s Static Global Assessment scale, where zero points indicated no lesions and five points indicated severe acne. Results: As a result of the consumption of 50 g of chocolate, a statistically significant intensification of acne lesions was observed in both groups. After 4 weeks of following the chocolate diet, the severity of acne lesions increased from 2.5 ±: 0.7 to 3.4 ±: 0.8 points (p <: 0.0001) in group A, and from 2.4 ±: 0.7 to 3.5 ±: 0.6 points (p <: 0.0001) in group B. Overall, chocolate intake contributed to the exacerbation of acne lesions by one point in 65 participants, by two points in 13 participants and by three points in one participant. Conclusions: The obtained results suggest that daily consumption of 50 g of chocolate with 85% cocoa content, even with an anti-inflammatory diet, may intensify acne lesions in this study group. However, it remains unclear which chocolate components may lead to the exacerbation of acne.
