Cholesterol
One of the skin’s three key barrier lipids, working with ceramides and fatty acids to keep skin supple and hold in moisture.

What it does
Essential for healthy, functioning skin, cholesterol helps keep our barrier intact and supple, and, with ceramides and fatty acids, forms the lipid “mortar” between skin cells. The result is hydrated, smooth skin.
How it works
Cholesterol used in skincare usually comes from lanolin (wool wax) or is made synthetically; plant versions, called phytosterols, work in a similar way. Rather than binding water itself, it helps the barrier hold on to moisture. It is also added to creams as a thickening agent, where it adds richness. The skin makes less of it with age, so it works best in moisturisers that combine all three barrier lipids.
MG says
Cholesterol is a naturally occurring molecule in the skin, responsible for ensuring the efficient function of the skin’s lipid barrier as well as maintaining optimal moisture levels. I love Valmont Prime Regenera II, which pairs it with ceramides and fatty acids, after a long-haul flight, in cold weather or whenever my skin feels dry, stressed or sensitised, and I often apply a thick layer as a 20-minute mask.
Cautions
Cholesterol is generally well tolerated, including by sensitive skin. It is often derived from lanolin, so check the source if you avoid animal-derived ingredients.
