The evidence, graded
emergingCeramides, cholesterol and free fatty acids are three lipids the skin barrier needs. In studies on damaged skin, mostly in mice, putting on one or two of them slowed repair, while equal amounts of all three let it recover normally. Raising any one of the three, up to three times the others, sped repair further. Early tests on damaged human skin looked similar.Man 1996 · Journal of Investigative Dermatology ↗
