What it is
Ceramide AG is one of the ceramide-class lipids, the family of waxy molecules that form a major part of the skin's natural barrier in the stratum corneum. Added to skincare and sunscreens, it helps replenish skin lipids and supports a smooth, conditioned, comfortable surface. It is typically used at low levels for its barrier-supporting and softening benefits.
Safety & warnings
Ceramides are skin-identical lipids and are generally very well tolerated, including by those with dry or sensitive skin. They are not associated with notable irritation at typical use levels.
Origin & sourcing
It is a ceramide-type lipid; modern cosmetic ceramides are commonly produced synthetically or by biotechnological methods to match the structure of skin-identical lipids.
