Ceramides are lipids that hold skin cells together — the literal mortar between the bricks. As skin ages, gets damaged by over-exfoliation, or loses moisture from harsh cleansers, ceramide content drops. Topical ceramides genuinely replenish what's missing.
Why they're different from other moisturisers
Most moisturisers add water (humectants) or seal it in (occlusives). Ceramides are structural — they actually become part of the skin barrier rather than sitting on top. The repair effect compounds over weeks, not minutes.
CeraVe and Dr Jart Ceramidin are the two ranges most dermatologists default to. The CeraVe Moisturising Cream at around £15 for 340ml is the price-performance benchmark.
How to spot a real ceramide product
Look for ceramide NP, ceramide AP, or ceramide EOP in the ingredient list — these are the three main types found in skin. 'Ceramide complex' without specifics may contain trace amounts only.
Ratio matters: a product with cholesterol and free fatty acids alongside ceramides (the natural 'lamellar' ratio) outperforms ceramides alone. CeraVe formulas all include this triplet.
Who benefits most
Post-retinoid users (any prescription retinoid strips barrier lipids), eczema-prone skin (chronic ceramide deficiency), winter dryness (UK November-March), and over-exfoliators recovering. Apply morning and evening for 4-6 weeks for visible repair.
Ceramides are one of the few skincare ingredients where the cheap drugstore option (CeraVe) is also the gold standard.
