A natural structural ingredient in the cell membrane that maintains moisture levels and helps prevent moisture loss to protect against dryness and thinning.
Naturally occurring skin lipids (fats) that are major structural components of the skin's outer structure and are necessary for the skin's water-retention capacity as well as cell regulation.
Epidermal lipids which, through their bilayers located between corneocytes, form a sort of cement. They play an essential role in the mechanisms of hydration.
(a lipid) A natural substance within the skin that reduces water loss by forming a protective barrier. The aging process gradually depletes these lipids and ceramides found in moisturizers or other skin products can replace these lipids and improve the suppleness and moisture content of the skin.
A natural substance within the skin that reduces natural water loss of the skin by forming a protective barrier. Can also be produced synthetically and added to skin care products
