Panthenol (Vitamin B5)
A soothing, hydrating provitamin that accelerates healing and reinforces the skin barrier — the calming hero your routine needs.
What Is Panthenol (Vitamin B5)?
Panthenol, also known as provitamin B5 or dexpanthenol, is the alcohol analog of pantothenic acid (vitamin B5). When applied to the skin, panthenol is rapidly converted to pantothenic acid, which serves as a crucial component of coenzyme A — essential for cellular metabolism and the synthesis of fatty acids and sphingolipids (including ceramides). In skincare, panthenol functions as both a humectant (attracting moisture to the skin) and a soothing agent, making it invaluable for irritated, dry, or compromised skin. It has been used in pharmaceutical wound-healing preparations for decades and is one of the most well-studied skin-soothing ingredients. Its ability to reduce transepidermal water loss while calming inflammation makes it a staple in K-beauty barrier-repair products and post-procedure recovery formulations.

How to Use Panthenol (Vitamin B5)
Panthenol is extremely gentle and can be used freely in both morning and evening routines. Apply panthenol-containing serums, toners, or creams after cleansing. For best results, layer panthenol with other hydrating ingredients (hyaluronic acid, glycerin) and barrier-repair ingredients (ceramides, fatty acids). Panthenol concentrations of 1–5% are typical in skincare products. It's particularly beneficial after exfoliation, retinol, or sun exposure when the skin needs calming and repair. No gradual introduction needed — panthenol is safe from first use.
