Ceramides: Comedogenic Rating & Safety Profile
Also known as: Ceramide NP · Ceramide AP · Ceramide EOP
Lipid molecules that make up roughly 50% of the skin's outer barrier. Topical ceramides replace what's lost through ageing, over-cleansing or inflammation.

Quick verdict
Ceramides is a emollient with a safe comedogenic profile (0/5) and safe irritancy (0/5). Lipid molecules that make up roughly 50% of the skin's outer barrier. Topical ceramides replace what's lost through ageing, over-cleansing or inflammation.
What is Ceramides?
Ceramides are lipid molecules that make up roughly 50% of the skin's outermost barrier (the stratum corneum). They function as the 'mortar' between skin cells, holding the barrier together and preventing water loss. The body produces nine main types of ceramide; topical skincare typically uses synthetic versions of ceramide NP, AP and EOP, which mimic the body's natural ceramides exactly. Ceramide synthesis declines naturally with age and is also disrupted by over-cleansing, acid use and conditions like eczema.
Comedogenic Rating: What 0/5 Means for Your Skin
Ceramides are rated 0/5 comedogenic. They are structural lipids that integrate into the skin barrier rather than sitting on top of pores. They are universally well-tolerated by all skin types.
Benefits for skin
- Restore the skin's natural moisture barrier
- Reduce transepidermal water loss
- Help calm eczema and rosacea flares
- Compatible with every active and skin type
Potential side effects & who should avoid it
Ceramides are exceptionally well-tolerated. Allergy and irritation are essentially unreported. They are recommended for all skin types and for managing eczema, rosacea and barrier-damaged skin.
Best for
- All skin types
- Dry
- Sensitive
- Eczema
- Mature
- Compromised barrier
Avoid if
No widely reported groups need to avoid this ingredient. Patch-test if you have a history of sensitivities.
How to use Ceramides safely
Use a ceramide moisturiser morning and night. Especially important after using retinoids, acids or any active that disrupts the barrier. No interaction risk with any other ingredient.
Commonly found in
Ceramides are in moisturisers, serums, cleansers and many barrier-repair products. The most effective ceramide moisturisers pair ceramides with cholesterol and free fatty acids in a 3:1:1 ratio (the ratio found in healthy skin).

Other emollients to know
Shea Butter
A rich, vitamin-packed plant butter from the African shea tree. Deeply emollient and softening, it's a classic ingredient for dry, mature and sensitive skin.
Isopropyl Myristate
A synthetic ester used to give products a dry, non-greasy slip. Despite its pleasant feel, it is one of the most pore-clogging ingredients in cosmetics.
Capric Triglyceride
A lightweight, refined fraction of coconut and palm fatty acids. Despite its origin, it is far less comedogenic than whole coconut oil.
Isopropyl Palmitate
A synthetic ester used to give creams and lotions a dry, silky slip. Highly comedogenic — best avoided in leave-on facial products if you are acne-prone.
