Ceramides

Ceramides are skin-identical lipids that are essential for a healthy skin barrier. They’re one of the most powerful actives used in modern skincare, dermatology, and sensitive-skin formulations.

INCI Name: Ceramide NP (Ceramide 3)

Function: Barrier repair & moisture retention

Why ceramides are so effective:

• Repair damaged skin barrier
• Reduce transepidermal water loss (TEWL)
• Improve hydration & elasticity
• Calm eczema-prone & sensitive skin
• Strengthen skin against acne, irritation & over-exfoliation
• Support anti-aging routines
• They don’t exfoliate or “force change” — they restore.

Application:

• Moisturizers & barrier creams
• Serums & lotions
• Cleansers (low % for rinse-off)
• Baby & sensitive-skin products
• Post-procedure skincare
• Acne-repair routines (with retinoids or acids)

Usage levels (important)

• Ceramides are used at very low concentrations:
• Leave-on products: 0.05–1.0%
• Cleansers: 0.01–0.2%
• More is not better — effectiveness comes from correct structure, not high %.
• Solubility: Water
• Ideal pH: 4.5–7.0
• Heat sensitive — avoid prolonged heating

✅️ Best-performing combinations

Ceramides work best with:

• Cholesterol
• Free fatty acids (linoleic acid, stearic acid)
• Humectants: glycerin, hyaluronic acid
• Soothers: panthenol, allantoin, centella
• 👉 This mimics natural skin lipid structure.
• 🛡️ Preservation & stability
• Ceramides do not preserve products
• Any water-based formula needs a preservative
• Stable in well-emulsified systems
