The burden of disease associated with acne vulgaris has continued to increase over time in the world population. This continued growth suggests that there is an unmet dermatologic need for this condition worldwide. Potential sequelae of acne, such as scarring, depigmentation, and marked emotional and psychological problems (e.g., low self-esteem), can lead to significant morbidity. The purpose of this study was to investigate whether dietary supplementation with magnesium, phosphate, omega 6 (linoleic acid calcium salt – C18:2 fatty acid Ca salt), and omega 7 (palmitoleic acid calcium salt – C16:1 fatty acid Ca salt) would help patients with acne vulgaris, and to compare with isotretinoin (13-cis retinoic acid). Magnesium has anti-inflammatory properties. Linoleic and palmitoleic acids have bactericidal activity against Staphylococcus aureus and Cutibacterium acnes (formerly known as Propionibacterium acnes). A single-blind randomized study was conducted in which 257 patients were treated with the above dietary supplementation (group A) and 275 patients with isotretinoin (group B) for 6 months. All patients in group A (100%) reported complete regression of symptoms after 6 months of treatment. On the other hand, 187 subjects (68%) in group B reported complete resolution of symptoms during the same period. The difference between the groups (p < 0.05) was statistically significant. The study was approved by the CEP/CONEP. This natural formulation promotes regression and/or cure of acne vulgaris symptoms and has better results than drugs (such as isotretinoin), without significant side effects.
