Ceramides
Lipids naturally found in skin that help hold moisture in and keep irritants out by supporting the skin's protective barrier.
Ceramides are a family of waxy lipid molecules that occur naturally in the outermost layer of your skin, the stratum corneum. Think of skin cells as bricks; ceramides are a key part of the mortar between them. They make up roughly 50% of that intercellular "mortar," which is why they play such a central role in how well your barrier holds together and retains water.
In skincare formulations, ceramides are typically delivered alongside complementary lipids like cholesterol and fatty acids, mimicking the ratio found in healthy skin. This combination is important because ceramides on their own are less effective than when presented in a balanced lipid mix. You'll find them in moisturisers, serums, and barrier-support creams, often at concentrations that support the skin's existing lipid structure rather than overwhelming it. They're generally well tolerated across skin types, including skin that leans sensitive.
Ceramides are worth considering if your skin feels tight, rough, or easily irritated, or if you're using active ingredients like retinoids or exfoliating acids that can temporarily compromise barrier function. Pairing a ceramide-rich moisturiser with these actives can help support your skin while it adjusts. They also work beautifully alongside humectants like hyaluronic acid: the humectant draws water in, and the ceramides help seal it there.
Honest limits: ceramides are fundamentally about barrier support and moisture retention. They won't address concerns like pigmentation or loss of firmness on their own, and no single ingredient is a complete skincare routine. If your skin barrier feels persistently compromised despite consistent gentle care, it's worth speaking with a dermatologist or skincare professional to understand what else might be going on.
