Deep Dive

Cholesterol is one of the three major barrier lipids (alongside ceramides and free fatty acids). Skin barrier function depends on all three being present in the right molar ratio. Many "ceramide" moisturizers skip cholesterol entirely, which limits their actual barrier-repair potential. CeraVe, EltaMD, and Skinceuticals Triple Lipid Restore include all three at physiologic ratios — the gold-standard approach.
