An omega-3 fat — fed with linoleic acid to lab-grown skin, it ended up in the skin's fats and the barrier improved.
What it does
Alpha-linolenic acid (ALA) is an omega-3 fat. Its barrier evidence is one lab study that fed lab-grown skin two fats at once, so it can’t say which one helped. A review lists barrier upkeep among the roles of omega-3 and omega-6 fats as a group.
The evidence, graded
emergingAlpha-linolenic acid (ALA) is an omega-3 fat. In one lab study, skin grown in a dish was fed ALA together with linoleic acid (LA), an omega-6 fat, through its growth liquid. Less of a test chemical passed through it, a sign of a better barrier, and its fats looked more like real skin's. ALA was not tested alone or put on skin. A review lists barrier upkeep among the roles of omega-3 and omega-6 fats as a group.Simard 2022 · Acta Biomater ↗
