Linoleic acid (LA) affects sebocytes—the cells that produce skin oil—differently than palmitic acid does, triggering changes in genes related to cholesterol production, hormone signaling, and skin cell turnover. LA creates more dramatic changes to the lipid profile in these cells than arachidonic acid, suggesting it could be a powerful tool for managing sebum production in acne-prone skin.

Researchers tested three different fatty acids on human sebocytes in a lab using genetic sequencing and lipid analysis to compare how each one changed gene expression and oil production.
