What Is Ceramide? — The Skin Barrier's Backbone
Ceramides make up 50% of skin's lipid composition. The right products replenish what aging and washing strip away.
The science.
Ceramides are lipid molecules that form the skin's outer barrier. They hold cells together, retain moisture, and protect against environmental aggressors.
How it works
Topical ceramides supplement what skin loses through age, washing, and harsh products. Replenishment supports barrier function.
Right for which skin types?
All skin types. Essential for dry, sensitive, eczema-prone, and mature skin.
How to use it
In moisturisers and creams. Look for ceramide-1, ceramide-3, ceramide-6-II, and the physiological 2:4:2 ratio.
Side effects
None.

Common questions.
Why do I need ceramides?
Skin loses 1% of ceramides yearly after age 20. Replenishment supports barrier function.
Are all ceramides created equal?
No. Ceramides 1, 3, and 6-II in physiological ratios are most effective. SkinCeuticals' 2:4:2 ratio is the clinical standard.
How long until ceramides work?
Barrier improvement: 4-8 weeks. Compounding effect over years.
