For your skin
A fatty acid from coconut oil with striking antimicrobial activity against acne bacteria. In lab tests it outperforms benzoyl peroxide at lower concentrations. The research is promising but limited to in vitro and animal models; no large human RCT yet. Worth noting: the concentrations used in the studies are far higher than what arrives via a coconut-oil facial oil, so look for formulas that list it as a dedicated active if you want the therapeutic dose.

A 12-carbon saturated fatty acid that disrupts the lipid bilayer of Cutibacterium acnes (formerly Propionibacterium acnes) membranes, achieving MIC values over 15× lower than benzoyl peroxide in vitro. In vivo mouse-ear models show it reduces C. acnes colony counts and suppresses granulomatous inflammation. Delivered via liposomes, the antimicrobial effect is dramatically amplified. Main natural source in skincare is coconut oil, but efficacy studies use purified lauric acid at concentrations well above what coconut oil typically delivers.
