Yes, vitamin D may help with acne. Several studies have demonstrated a correlation between low levels of vitamin D and acne severity.

1. Vitamin D Deficiency and Acne Severity: Research indicates that individuals with acne tend to have lower levels of serum 25-hydroxy vitamin D compared to those without acne¹². A significant inverse correlation was found between vitamin D levels and acne severity, suggesting that lower vitamin D levels are associated with more severe acne³.

2. Supplementation Benefits: Some studies have shown that vitamin D supplementation can improve acne conditions, particularly in individuals who are deficient in vitamin D⁴. For instance, a trial involving acne patients with vitamin D deficiency exhibited improvement in inflammatory lesions after supplementation⁵.

3. Mechanisms: Vitamin D is known to modulate the immune system, reduce inflammation, and affect the proliferation and differentiation of skin cells, which are all factors involved in the pathogenesis of acne⁶.

Despite these findings, it's important to consult with a healthcare provider before starting any supplementation, as the response to vitamin D can vary between individuals, and excessive intake may lead to other health issues.
