Barrier repair and moisture-retention for compromised skin

Fine Line WrinklesLoss of CollagenAcne

In plain English

Ceramides are naturally occurring lipid molecules that make up the skin's waterproof barrier. When this barrier is depleted (by ageing, eczema, over-exfoliation, or harsh products), skin becomes dry, reactive, and sensitised. Topical ceramide moisturisers replenish these lipids to restore the barrier. They are exceptionally safe, recommended for eczema, and one of the most clinically appropriate ingredients for anyone with sensitive or compromised skin.

Safe for skin types

Safe forAll Fitzpatrick types I–VI

Ceramide moisturisers have no chromophore activity and are universally safe and beneficial. They are particularly important in darker skin types after using actives like retinoids or AHAs, as barrier repair reduces PIH-triggering irritation.

Common misconceptions

✕Myth

“Ceramide moisturisers are only for people with eczema.”

✓Reality

Ceramides are appropriate for any skin type. For oily or acne-prone skin, lightweight ceramide formulations support barrier function without clogging pores. For dry or ageing skin, they are especially valuable. For anyone using retinoids or AHAs, a ceramide moisturiser is strongly recommended to counteract barrier disruption from those actives.

✕Myth

“Any moisturiser will repair the skin barrier equally well.”

✓Reality

Occlusive-only moisturisers (petrolatum, mineral oil) reduce TEWL by physical film-forming but do not replenish SC lipids. Ceramide formulations provide both occlusion and structural lipid replacement, which research shows produces superior and more sustained barrier repair.

✕Myth

“Phytoceramides (from plants or supplements) work the same as topical ceramides.”

✓Reality

Oral phytoceramide supplements have a separate evidence base (intestinal absorption and systemic distribution to skin). Topical plant-derived pseudo-ceramides are structurally distinct from human SC ceramides. Whether they integrate identically into the lamellar bilayer is not fully established, though they have demonstrated skin hydration benefits in clinical studies.
