CERAMIDE III is a ceramide that reinforces the skins natural protective lipid barrier. CERAMIDE III consists of a Phytosphingosine backbone acylated with a saturated fatty acid (stearic acid). CERAMIDE III and CERAMIDE IIIB support the renewal of the skin’s natural protective layer and form an effective barrier against moisture loss. These human-skin-identical molecules are therefore particularly suitable for long term protection and repair of sensitive and dry skin. In hair care formulations CERAMIDE III and CERAMIDE IIIB are able to restore damaged hair and to protect hair against chemical and UV damage.
