What role does HDL play in Haut?

HDL (high-density lipoprotein) is commonly known as 'good' cholesterol because it transports excess cholesterol from blood vessels to the liver. Regarding skin health, HDL may play a supportive role through its anti-inflammatory and antioxidant properties. Low HDL levels are linked to chronic inflammation, which can impair skin barrier function and potentially worsen conditions like acne, psoriasis, or premature aging. However, direct causal evidence for HDL and skin is limited to observational and mechanistic studies; no large-scale RCTs have confirmed a specific benefit. Additionally, there are no established clinical cutoffs for HDL in dermatology, and topical HDL is not used in skincare. For skin health, proven strategies include a balanced diet, adequate sleep, sun protection, and a consistent skincare routine. If blood HDL is low, it should be addressed primarily for cardiovascular risk reduction. MyBody-X tests can measure HDL, but any skin-related interpretation remains speculative and should be discussed with a healthcare provider.
