Panthenol (Vitamin B5)
Panthenol is the provitamin form of vitamin B5 (pantothenic acid) and one of the most reliable, gentle, and effective ingredients in skincare. When applied topically, it converts to pantothenic acid in the skin, where it plays a crucial role in barrier repair, wound healing, and hydration. Panthenol acts as both a humectant (attracting water) and an emollient (softening skin), making it a dual-function moisturizing ingredient. Its anti-inflammatory properties make it particularly valuable for sensitive, irritated, and compromised skin. Panthenol appears in everything from healing ointments to serums to sunscreens because it improves virtually every product it is added to. It has an exceptionally strong safety profile with no known irritation or sensitization risk at any concentration used in cosmetics.
How Panthenol Works
Panthenol penetrates the skin and converts to pantothenic acid (vitamin B5), which is a component of coenzyme A -- essential for lipid synthesis and barrier repair. It increases skin hydration by acting as a humectant, drawing water into the stratum corneum. It stimulates lipid synthesis in the epidermis, directly supporting barrier repair. It accelerates epidermal regeneration, which is why it is used in wound healing products. Anti-inflammatory activity reduces redness and irritation. Clinical studies show measurable improvements in skin hydration, barrier function, and wound healing at 2 to 5 percent concentration.
