Dexpanthenol function:
1.In pharmaceuticals, cosmetics and personal-care products, panthenol is a moisturizer and humectant, used in ointments, lotions, shampoos, nasal sprays, eye drops, lozenges, and cleaning solutions for contact lenses.
2.In ointments it is used for the treatment of sunburns, mild burns, minor skin injuries and disorders (in concentrations of up to 2–5%). It improves hydration, reduces itching and inflammation of the skin, improves skin elasticity, and accelerates epidermal wounds' rate of healing. For this purpose, it is sometimes combined with allantoin.
3.It binds to the hair shaft readily; so, it is a common component of commercial shampoos and hair conditioners (in concentrations of 0.1–1%). It coats the hair and seals its surface,[citation needed] lubricating the hair shaft and giving it a shiny appearance.
4.It is also recommended by tattoo artists as a post-tattooing moisturising cream.
