What are ceramides?
Ceramides are essential lipids (fats) naturally found in the outermost layer of your skin, known as the stratum corneum. Think of your skin as a brick wall: the skin cells are the bricks, and ceramides are the mortar holding everything together. Without ceramides, this wall becomes weak, allowing moisture to escape and evaporate while letting in harmful irritants to enter.
The science behind ceramides
-
Ceramides make up approximately 50% of the lipids in the skin barrier.
-
They create a protective layer that stops water loss and keeps out environmental stressors
-
Ceramides work together with cholesterol and fatty acids to maintain the skin’s integrity and hydration.
-
Ceramides are part of a group of molecules called sphingolipids, produced in the skin’s living layers.
-
Naturally produced by the body, but sphingolipid levels decline with age, harsh weather conditions and overuse of drying products.
Ceramides and Skin Health
Your skin barrier is essential for keeping your skin hydrated, smooth, and protected. However, natural ceramide levels decline with age—by your 30s or 40s, they’re much lower than in your 20s. Environmental factors like sun exposure, harsh weather, pollution, and over-cleansing can speed up this process, leading to:
- Dryness: Without enough ceramides, your skin loses moisture and becomes flaky.
- Sensitivity: A weakened barrier is more vulnerable to irritation.
- Signs of Aging: Reduced ceramides can lead to wrinkles, dullness, and loss of elasticity.
Ceramides are key to keeping your skin strong and healthy.
What happens if your skin lacks ceramides?
When your skin lacks ceramides, several problems can arise:
-
Dryness and flakiness: Skin loses its ability to retain moisture.
-
Increased sensitivity: The weakened barrier allows irritants to penetrate, causing redness and discomfort.
-
Premature aging: Fine lines and wrinkles appear faster due to chronic dehydration and a weakened skin barrier.
-
Worsened skin conditions: Issues like eczema, rosacea or psoriasis may flare up without proper barrier protection.
Why are ceramides beneficial in skincare?
Ceramides are skincare superheroes for many reasons:
-
Hydration: They lock in moisture - keeping your skin plump and hydrated.
-
Barrier repair: Ceramides help rebuild a damaged skin barrier, making it more resilient and durable agains environmental stressors.
-
Soothing effects: They calm irritation and reduce redness, especially in sensitive skin.
-
Anti-aging benefits: Ceramides improve skin elasticity and reduce the appearance of fine lines over time.
How to start using ceramides in skincare (beginner-friendly guide)
-
Choose a ceramide moisturiser: Start with a simple, fragrance-free option for daily hydration & nourishment.
-
Add a ceramide serum: Apply before moisturising for extra hydration and repair.
-
Use ceramide sunscreen: Protect skin from UV damage while strengthening the skin barrier.
-
Be consistent: Regular use is key to seeing results.
Key ingredients ceramides work well with
Ceramides pair well with other skincare ingredients to enhance their benefits:
-
Hyaluronic acid: Attracts water into the skin, working alongside ceramides to lock in hydration.
-
Niacinamide: Boosts ceramide production and improves skin tone.
-
Cholesterol and fatty acids: Complements ceramides to strengthen the skin barrier.
-
Panthenol (vitamin B5): Soothes irritation and enhances ceramide’s calming effects.
-
Peptides: Stimulate collagen production and improve skin elasticity, amplifying ceramide’s anti-aging benefits.
-
Vitamin A (RETINOL, RETINAL): Ceramides help reduce the irritation and dryness that sometimes happens with vitamin A treatments.
Ceramide summary
Ceramides are very important for maintaining healthy, hydrated, and strong skin. They work by restoring and protecting your skin’s barrier, stopping issues like dryness, sensitivity and premature signs of aging.
Starting with a simple ceramide moisturiser or serum is perfect for beginners and pairing ceramides with hydrating and soothing ingredients can maximise their effectiveness. Whether you’re new to skincare or a skincare pro, ceramides are a must-have ingredient for everyone.
