Ingredient pairing

Can I use ceramides, cholesterol, and fatty acids together?

Short answerYesModerate evidence: At least one human study or a well-supported mechanism, but not yet full scientific consensus.

Yes — a cited synergy. Barrier repair needs all three stratum-corneum lipids together; supplying them in physiologic proportion (roughly 3:1:1, one component dominant) speeds permeability-barrier recovery, while incomplete mixes can delay it.
