Common Name(s): (9z,12z)-octadecadienoic acid,cis,cis-9,12-octadecadienoic acid,la
CAS Number: 60-33-3
DESCRIPTION
What It Does: Provides essential omega-6 fatty acid for ceramide-1-linoleate synthesis and anti-comedogenic barrier repair.
Why It's Used: The essential barrier-repair fatty acid โ linoleic acid deficiency directly causes barrier dysfunction and acne-like lesions; topical replacement addresses this documented deficiency.
How It Works: Essential (cannot be synthesized) โ must be supplied via diet or topically. incorporated into ceramide-1 via omega-hydroxylation to form the long-chain ceramide that seals corneocyte protein envelope. sebum linoleic acid deficiency in acne directly causes follicular plugging (comedogenesis).

SCIENTIFIC NOTE
Linoleic acid deficiency in sebum is a defining biochemical feature of acne-prone skin: sebum la concentration is 25-40% lower in acne patients vs controls. this deficiency impairs ceramide-1-linoleate synthesis, weakening the follicular barrier that normally prevents p. acnes colonization. topical linoleic acid directly supplements this deficient essential fatty acid โ a targeted nutritional mechanism unique among anti-acne ingredients.
