PANTHENOL
Panthenol, also known as pro-vitamin B5, is well absorbed when applied topically to the skin and is rapidly oxidized enzymatically in the body to pantothenic acid (vitamin B5). Vitamin B5 is a component of coenzyme A, which is involved in various physiological processes such as intracellular lipid synthesis in the epidermis.(1)(2) Panthenol penetrates the skin better than vitamin B5 and is very well tolerated.(1-3) Panthenol has a skin-nourishing and moisturizing effect and strengthens the skin's barrier function. (2-5) In dry skin, it compensates for reduced hydration by increasing the water content and positively influencing the molecular mobility of the lipid lamellae and proteins of the stratum corneum, thus also reducing transepidermal water loss. (4)(5) Panthenol can support wound healing in burns, burn wounds, corneal lesions and allergic dermatitis in all three phases of wound healing and has a protective effect against skin irritation.
