Background: Laser hair removal (LHR) is a common procedure for the removal of unwanted hair. Although it is generally safe, it is associated with some adverse effects including hyperpigmentation. Purpose: In this study, we aimed to assess the prevalence of postlaser hyperpigmentation in patients taking Vitamin D supplements. Methods: This is a cross-sectional study of patients who underwent LHR. Each patient was interviewed and asked about their intake of Vitamin D supplements, and the primary outcome was whether hyperpigmentation was reported after LHR in the past 6 months. LHR treatment details were also documented. Results: A total of 508 patients were included with a mean age of 29 ± 9 years. Post-LHR hyperpigmentation was more prevalent in females and in those taking oral Vitamin D. Multivariate logistic regression analysis showed that Vitamin D intake was independently associated with more risk of hyperpigmentation post LHR (odds ratio [95% confidence interval]; 2.6 [1.17–5.80], P = 0.020). Conclusion: Vitamin D intake may be associated with an increased risk of hyperpigmentation post LHR. Causality cannot be assessed.
