In sintesi

One of the most sensible 'comfort and barrier' ingredients: ceramides are part of your skin's own mortar, and replacing them helps dry or barrier-stressed skin. Best evidence is for restoring the barrier, not dramatic anti-aging.

Cosa dice l'evidenza

Ceramides are a major lipid component of the skin barrier, and their depletion is linked to dryness and barrier dysfunction. Controlled studies of ceramide-containing moisturisers (often with cholesterol and fatty acids in a physiological ratio) show improved hydration, reduced trans-epidermal water loss and better comfort in dry or barrier-compromised skin. This is a cosmetic barrier-support claim, not treatment of any skin disease, and the finished product's ratio and formulation matter as much as the presence of ceramides on the label. Grade B for solid barrier evidence.

Meccanismo

Replenish the intercellular lipid matrix ('bricks and mortar' model) that limits water loss and keeps the barrier intact; work best alongside cholesterol and free fatty acids in balanced proportions.

Sicurezza

Very well tolerated, including on sensitive and dry skin; among the lowest-irritation actives. Suitable for frequent use.

Contesto dosaggio

Effect depends on the full lipid formulation rather than a single percentage; products combining ceramides with cholesterol and fatty acids in a physiological ratio have the best support.

Esempi di applicazione

  • Used in a moisturiser, ideally with cholesterol and fatty acids.
  • Layered over hydrating serums to seal in water.
  • A go-to for dry, tight or barrier-stressed skin.

Nota dal campo

Ceramides are the 'comfort and barrier' pick that actually makes sense — they're literally part of your skin's mortar. We grade them B and keep the claim honest: restore the barrier, don't promise a facelift.
