Can HDL help with Haut?

Whether HDL (high-density lipoprotein) can benefit the skin is not firmly established by current evidence. HDL is best known for its cardiovascular protective role – it transports excess cholesterol from arteries to the liver. For skin, mechanistic studies suggest HDL has antioxidant and anti-inflammatory properties that could theoretically slow skin aging or support conditions like psoriasis or acne. HDL is also implicated in wound healing. However, these findings come mostly from cell and animal experiments or small observational studies. Large-scale randomized controlled trials in humans are lacking to confirm a direct causal benefit of HDL for skin. Moreover, HDL levels are only modestly modifiable through lifestyle (exercise, Mediterranean diet, moderate alcohol), and such changes are not specifically targeted at skin. Genetic variants like rs662799 in APOA5 influence HDL and triglyceride levels, but their effect on skin is unproven. In summary, while HDL is a valuable marker of overall health, the evidence for a direct skin benefit is weak to moderate. For improving skin health, proven strategies like sun protection, moisturizing, and a balanced diet remain more reliable.
