The importance of ceramides in skin care products

The proper moisture levels and the protective outermost skin layer rely critically on ceramides, indispensable lipids that compose up to 40% of the skin cells. Skin dryness, problems and irritations may result from ceramide depletion caused by aging. Ceramides are frequantly used as an active ingredient in skin care products such as face creams, face serums and face tonics. Ceramides are particularly recommended for use in colder seasons and for aging skin all year round.

Two types of ceramides are utilized in cosmetic products: natural and synthetic. Soy and skin both contain natural ceramides. On the contrary, synthetic ceramides are created in a laboratory and have superior stability to natural ceramides, which means they are frequently utilized in skin care products, because they can be easily incorporated into cosmetic formulations.

Ceramides are created from sphingosine, an unsaturated amino alcohol that can bind with various fatty acids to produce 12 separate ceramide variations.

The following ceramides are commonly used in skin care products:

• Ceramide 1, also called ceramide EOS
• Ceramide 2, also called ceramide NS or NG
• Ceramide 3, also called ceramide NP
• Ceramide 6-II, also called ceramide AP
• Ceramide 9, also called ceramide EOP
• Phytosphingosine

The skin's protective barrier and resistance to environmental factors are maintained by ceramides that prevent water loss and reduce the depth of fine lines. As one's skin ages, the probability of developing atopic dermatitis and eczema grows due to the decreasing levels of ceramide. Skincare products with ceramides are vital in combatting dryness, sensitivity, and signs of aging. Ceramide EOS, NP, and/or AP, along with sphingosine or phytosphingosine are recommended in products to address dry skin concerns. For optimal mature skin results, combine ceramides with other beneficial ingredients having antioxidant effects like niacinamide, retinol, peptides, or linoleic acid.
