Can ApoB help with skin aging?

Whether ApoB (apolipoprotein B) can help with skin aging is not supported by direct evidence. ApoB is a core protein of LDL and VLDL particles and is primarily used as a cardiovascular risk marker. Mechanistically, oxidized ApoB-containing lipoproteins can promote oxidative stress and inflammation, which are known to accelerate skin aging by damaging collagen and elastin. However, no robust human studies have demonstrated that lowering ApoB levels improves skin aging outcomes. The evidence is therefore mechanistic at best and remains unclear. For skin health, established measures such as sun protection, antioxidants, hydration, and a balanced diet are far more relevant. ApoB testing is not indicated for skin aging concerns.
