What it is
Ceramides are a group of lipids (there are 9 different types) that make up about 50% of the skin’s natural protective barrier, preventing moisture from evaporating from the skin, thus keeping it hydrated and moisturized.
What it does
When applied topically, Ceramides can help restore the levels of reduced ceramides in the skin, thus rebuilding the protective barrier so that skin is hydrated and its appearance improved.
Although touted to be a powerful antioxidant, there is no scientific proof that ceramindes help fight or prevent the signs of aging. They simply work only as a moisturizing agent.
Unfortunately Ceramides are scarce and that’s why products containing them tend to be on the expensive side.
