Details

Jojoba Oil/Macadamia Seed Oil Esters is the major component of a skin surface lipid mimetic mixture trade named L22.  

So what the heck is a skin surface lipid mimetic mixture? Let's start with skin surface lipids (SLSs): these are the oily substances that your skin produces (mainly the sebaceous glands, a smaller part comes from the epidermis) to keep the skin nice and moisturized. The main components are fatty acids (FAs), triglycerides, cholesterol, cholesteryl esters, wax esters, and squalene. This mixture has a super important role in keeping the skin barrier healthy. 

So Jojoba Oil/Macadamia Seed Oil Esters is a jojoba and macadamia oil-derived ingredient that contains fatty acids, triglycerides, and wax esters. It comes to the formula with Squalene,  Phytosteryl Macadamiate (botanical sourced version of cholesteryl ester) and Phytosterols (botanical version of cholesterol) in the ratios found in young, healthy adult skin.  

So the main skill of L22 is barrier repair and skin hydration and the manufacturer did several double-blind, vehicle-controlled studies to show it really works. It compared 3% of L22 with 3% of olive oil or 3% of caprylic/capric triglyceride alone or combined with Ceramide 2 in a vehicle. 60 minutes after the application, barrier recovery was by far the best by the L22 + Ceramide 2 (0.1%) combination, followed by L22 alone, and then by Olive + Ceramide 2 and Olive alone. Skin hydration was measured 4 hours after application and again, the L22 + Ceramide 2 combination performed the best followed by L22 alone. 

Another study compared 3% L22 with 3% petrolatum (the gold standard occlusive agent). After 1 hour, they performed similarly both for barrier repair and skin hydration, but after 2 weeks of use and a 1 week regression period, L22 showed significantly better results. 

So the bottom line is: if barrier repair is something that you are interested in, the skin surface lipids of L22 can definitely be worth a try. Even better, if the formula also contains Ceramide 2
