Ceramides are one of skincare's quiet heroes — not flashy, but essential. They're a natural part of your skin's barrier, and topping them up is one of the most reliable ways to keep skin comfortable, resilient and well hydrated. Here's what they do and who benefits most.

What are ceramides?

Ceramides are a type of lipid (fat) that makes up a large part of the skin's outer barrier. The classic way to picture it: your surface skin cells are the bricks, and ceramides — along with cholesterol and fatty acids — are the mortar holding them together. That mortar is what keeps water in and irritants out. Your skin makes ceramides naturally, but levels fall with age, over-cleansing, harsh actives and cold weather.

What do ceramides do for skin?

  • Lock in moisture — a healthy ceramide layer sharply reduces water loss, so skin stays hydrated and plump.
  • Protect the barrier — they help defend against irritants, pollution and weather, so skin reacts less.
  • Calm and support — replenishing ceramides helps skin that feels tight, rough or sensitised feel comfortable again.

When ceramides run low, the barrier weakens — which shows up as dryness, tightness, redness and sensitivity. See signs of a damaged skin barrier and how to repair a damaged skin barrier.

Who should use ceramides?

Almost anyone can benefit, but they're especially worthwhile for:

  • Dry and dehydrated skin, which loses water more easily.
  • Sensitive or reactive skin, where the barrier needs extra support.
  • Anyone using strong actives like retinoids or acids, to offset dryness and irritation.
  • Mature skin, as natural ceramide levels decline with age.

How to use them

Ceramides are most commonly found in moisturisers and creams, which is exactly where they work best — as the sealing step. For the best results:

  • Apply a ceramide moisturiser over a hyaluronic acid or glycerin serum — the humectant draws in water, the ceramides seal it in.
  • Use morning and night; they pair happily with almost everything, including retinoids and vitamin C.
  • They're gentle and well tolerated, so they suit even reactive skin.

Ceramides for Skin FAQs

What do ceramides do for your skin?

They're barrier lipids that hold skin cells together, lock in moisture and protect against irritants. Topping them up keeps skin hydrated, resilient and less prone to dryness, tightness and sensitivity.

Who needs ceramides?

They benefit most people, and especially dry, dehydrated, sensitive or mature skin, and anyone using retinoids or acids. Barrier support is useful across the board.

Can I use ceramides with retinol or vitamin C?

Yes — ceramides are gentle and pair well with almost everything. In fact, using a ceramide moisturiser alongside retinoids or acids helps offset the dryness and irritation those actives can cause.

Are ceramides good for [[PROTECTED_70]]?

They can be. Oily skin can still have a compromised barrier, and lightweight ceramide moisturisers support it without feeling heavy. Choose a lighter texture if you're prone to congestion.

How do I use ceramides in my routine?

Use a ceramide-containing moisturiser as your sealing step, ideally over a humectant serum like hyaluronic acid or glycerin. Morning and night is fine, and they work alongside your other products.
