Ceramides
The lipids that make up roughly half of the skin barrier's structure. Applied topically — especially alongside cholesterol and fatty acids in physiological ratios — they replace what cleansing and age deplete, cutting water loss and reactivity. They are the backbone of barrier-repair formulas.
Ceramides by the numbers.
We've catalogued 448 products that use ceramides, most often in moisturizers (181 products) but also across serums and body cares. Formulations carrying it score 79/100 on average (well above the catalog norm); the strongest is CeraVe Moisturizing Cream at 92/100.
Of those, 239 products score 80 or higher in our analysis. It co-occurs most with Niacinamide (207 shared formulas) and Hyaluronic Acid (175 shared formulas). The median price of a ceramides product here is $26.
