Ceramides
Essential lipids that form the skin's barrier and retain moisture.
Also known as: Skin-identical ceramides • Phytoceramides
Overview
Ceramides are a class of fatty acids called lipids. They're naturally found in skin cells and make up about 50% of the outer skin layer (the epidermis). Ceramides are vital for forming the skin's natural barrier, which helps to retain moisture and protect against environmental aggressors. Supplementing with ceramides, often derived from plants (phytoceramides), can help replenish the skin's ceramide content, improving hydration, reducing wrinkles, and enhancing overall skin health.
Key Benefits
Improves Skin Hydration
Ceramides help lock moisture into the skin, preventing dryness and irritation.
Strengthens Skin Barrier
They are crucial for a healthy skin barrier, which protects against pollution, bacteria, and other environmental threats.
Reduces Wrinkles
By improving skin hydration and elasticity, ceramides can help diminish the appearance of fine lines and wrinkles.

A typical dose for phytoceramide supplements is 350 mg per day.
| Purpose | Dose | Notes |

| General Skin Health | 350 mg/day | Often derived from wheat germ oil or rice bran. |
| Enhanced Hydration | 700 mg/day | Higher doses may be used for more significant dryness. |
