What role does ApoB play in Haut?

ApoB (Apolipoprotein B) is a core protein of LDL and VLDL particles, primarily linked to cardiovascular risk. Its direct role in skin (Haut) is not well-established. Indirectly, ApoB-containing lipoproteins may influence skin health through oxidative stress or inflammation, but evidence is weak and mostly mechanistic. In dermatology, apolipoproteins like ApoE or ApoA1 are more relevant for local lipid metabolism. Consumer DNA tests reporting ApoB variants for skin concerns lack clinical validation. Such results should not be used for skincare decisions or diagnosis. For skin issues, consult a dermatologist. Evidence grade: mechanistic/unclear.
