Panthenol
A provitamin form of B5 that binds water to the skin and supports its natural barrier recovery.
Panthenol is the alcohol form of vitamin B5 (pantothenic acid) and belongs to the humectant and skin-conditioning ingredient class. Once absorbed into the skin, it converts to pantothenic acid, a nutrient involved in normal cellular processes including lipid synthesis and energy metabolism. You'll find it listed as panthenol or dexpanthenol on ingredient labels, and it's one of the most well-studied topical ingredients available.
In formulations, panthenol works primarily as a humectant, meaning it draws water into the upper layers of the skin and helps hold it there. It also has emollient properties, softening the skin's surface and reducing the feeling of tightness. Typical use concentrations range from around 1% to 5%, and it plays well in a wide variety of vehicles including serums, creams, lotions, and even cleansers. Because it's water-soluble and lightweight, it layers easily under other products without pilling or heaviness.
For shoppers, panthenol is worth considering if your skin feels dry, tight, or reactive. It pairs beautifully with ceramides and niacinamide to support barrier function, and it sits comfortably alongside most actives, including retinoids and exfoliating acids, where it can help offset potential dryness. It's gentle enough for sensitive skin types and is commonly included in formulations designed for post-procedure care or compromised barriers.
Honest limits: panthenol is a reliable supporting player, not a standalone solution for persistent dryness or barrier concerns that have deeper causes. It won't replace occlusives if your skin needs a stronger seal against moisture loss, and it doesn't address structural ageing or pigmentation. If your skin remains uncomfortable despite consistent hydration, that's a good prompt to speak with a skincare professional who can look at the fuller picture.
