Myths vs facts: LDL and Haut

The claim that LDL cholesterol directly causes skin issues like acne or premature aging is largely a myth. LDL is essential for lipid transport, but skin barrier function and inflammation are influenced by many factors. A well-established link exists only for xanthelasmas (yellowish cholesterol deposits under the skin), which are associated with elevated LDL levels. However, these deposits are benign and primarily cosmetic. Most skin conditions such as acne or wrinkling have complex causes (hormones, genetics, UV exposure, diet), with LDL playing a minor role. Consumer DNA tests that promise direct effects of LDL gene variants on skin health overstate the evidence. Validated biomarkers like vitamin D levels or inflammatory markers are more relevant for skin health. Bottom line: LDL is not a central skin factor; a balanced diet and lifestyle matter more than focusing solely on LDL levels.
