Can VDR help with Haut?

Whether the Vitamin D receptor (VDR) can help with skin issues is scientifically plausible but evidence remains largely mechanistic. VDR is expressed in keratinocytes and skin immune cells, regulating cell proliferation, barrier function, and inflammation. Some studies link VDR polymorphisms (e.g., rs2228570, rs1544410) to conditions like psoriasis, acne, or atopic dermatitis. However, effect sizes are small, study results are inconsistent, and translation into personalized supplement or skincare recommendations is not robustly supported. Direct clinical outcomes (e.g., improved skin appearance through targeted VDR modulation) lack strong evidence. VDR is often analyzed alongside other genes (GC, CYP2R1) and requires consideration of vitamin D status, lifestyle, and environment. A standalone VDR genetic test is of limited value for skin health. Safety note: vitamin D supplementation should be medically supervised to avoid toxicity.
