Can VDR help with skin aging?

The vitamin D receptor (VDR) is expressed in skin cells and influences cell proliferation, differentiation, and inflammatory responses. Some observational studies suggest that certain VDR polymorphisms (e.g., rs2228570, rs1544410) may be associated with premature skin aging, wrinkle formation, and loss of elasticity. Proposed mechanisms include reduced protection against UV damage and impaired collagen synthesis. However, the evidence is weak: mostly mechanistic or small association studies, not randomized controlled trials. A single DNA test cannot determine actual skin condition. Lifestyle factors—sun protection, diet, smoking cessation, and skincare—are far more impactful. Vitamin D supplementation may help if deficiency is confirmed, but a VDR-targeted anti-aging strategy lacks clinical support. Be cautious of marketing claims. For skin concerns, consult a dermatologist.
