Observational studies have found associations between higher HDL levels and fewer wrinkles or better skin elasticity, but these are likely confounded by overall healthy lifestyle. HDL does possess antioxidant and anti-inflammatory properties that could theoretically protect skin from oxidative stress. However, effect sizes are small, and no randomized controlled trials prove a causal benefit. Moreover, HDL is measured in blood, not directly in skin tissue. Factors like sun protection, smoking, diet, and sleep have far greater impact on skin aging. An isolated high HDL from drugs or genetics probably offers no skin advantage.

People with genetically very high HDL (e.g., CETP mutations) do not have lower fatigue risk. Marketing HDL as an 'energy booster' is misleading.

HDL (high-density lipoprotein) is often called 'good cholesterol' because it helps remove excess cholesterol from blood vessels. While low HDL is a risk factor for cardiovascular disease, it is not a direct cause of tiredness. Fatigue has many potential causes: poor sleep, stress, iron deficiency, hypothyroidism, or depression. An isolated low HDL level without other abnormalities typically does not produce noticeable fatigue. However, very low HDL (<30 mg/dL) may indicate metabolic syndrome or a genetic disorder, which can indirectly be associated with fatigue. The evidence is mostly observational (cohort studies), not causal. An HDL test alone is insufficient to explain fatigue. A comprehensive medical workup including complete blood count, thyroid function, vitamin D, iron, and inflammatory markers is more appropriate.
