Saturated fatty acid with 16 carbons. One of the baseline components of the skin's lipid mantle (approximately 20% of stratum corneum fatty acids). In cosmetics it is used as an emulsifier component and emollient. Also found in palm-oil-based soaps. At excess concentration it can leave a heavy film feel.
Topical application
BLimited evidence. One RCT or several controlled studies with limitations.
Functional barrier lipid. Paired with other fatty acids and ceramides it restores the lipid mantle. Has no standalone active effect. Safety profile is favourable.

Saturated fatty acid with 16 carbons.
On the Fulton scale 2/5 – low comedogenicity. For acne-prone skin, a rating of 3 or higher suggests choosing an alternative.
