Vitamin D Levels in Patients with and without Acne and Its Relation to Acne Severity: A Case-Control Study.

Conclusion: This study has shown clearly that vitamin D deficiency is more frequent in patients with acne with P-value = 0.003. However, no significant association between the serum level of 25-hydroxyvitamin D [25 (OH) D] and the severity of acne vulgaris. Further clinical trials on a larger scale are needed to address the importance of vitamin D in acne vulgaris. Specifically, determining whether treatment of acne with both topical vitamin D analogs and vitamin D supplementation is of significant effect. PMID: 33116739 [PubMed]
