Phosphatidylcholine
The details
Phosphatidylcholine (PC) is a type of phospholipid , a class of molecule that makes up our own cell membranes. It has a glycerol backbone, two fatty acid tails (mostly linoleic , palmitic , and oleic ), and a phosphate-choline head group. In skincare, PC pulls double duty: The linoleic acid it carries gets incorporated into skin ceramides and helps reinforce the lipid matrix. Interestingly, it can help top of the omega-6 fatty acid that's often low in acne-prone and atopic skin. There's a sizeable body of literature that supports its use in dry, barrier-impaired, and breakout-prone skin. There are two kinds of PC you'll see on ingredient lists. Use levels range from <1% as a liposomal carrier and between 20-40% in lamellar matrix sytems.
