Panthenol

Panthenol draws water into the outer skin layer and helps reduce water loss, so it leaves skin feeling softer and less tight. Studies of dexpanthenol creams, mostly from the 1990s and 2000s and often sponsored by manufacturers, report improved hydration, smoother skin and less redness after irritation, and support for the skin's natural renewal after minor damage. In hair products it is a film-forming humectant that adds moisture, slip and shine to the hair shaft; it does not change how hair grows.

In our directory: It’s a key ingredient in 12 products we review, most often wash day and serums. Those products are mostly built for hydrating, frizz control and dryness relief. In formulas, it most often shares the label with glycerin, hyaluronic acid and vitamin e.

Use in a serum, moisturizer or balm once or twice daily; it layers easily with most actives. In hair care it is typically found in conditioners and leave-ins.
