What to watch with HDL and skin aging?

HDL (high-density lipoprotein) is known as 'good' cholesterol and has anti-inflammatory and antioxidant properties that may influence skin aging. Observational studies suggest higher HDL levels are associated with fewer wrinkles and better skin elasticity, possibly due to reduced oxidative stress and inflammation. However, the evidence is not strong enough to establish causality. HDL is influenced by genetics (e.g., variants in CETP, LIPC) and lifestyle, but individual gene effects are small. A DNA test can reveal your HDL-related genetic variants, but it cannot provide a targeted anti-aging plan. Lifestyle factors—such as a diet rich in unsaturated fats and fiber, regular exercise, not smoking, and sun protection—are far more impactful. Focus on overall health rather than a single biomarker. If your HDL is very low (<40 mg/dL) or LDL is high, consult a doctor first; skin aging is secondary to cardiovascular risk.
