What Pantolactone does

Supports a soft, smooth skin feel
Serves as a building block for panthenol
Helps a formula feel comfortable on skin

Pantolactone is a small, ring-shaped molecule that sits close to pantothenic acid, better known as vitamin B5. In beauty, it is mainly known as a building block for panthenol, an ingredient used to help skin feel soft and hydrated. Pantolactone itself is usually made in a lab rather than taken from plants.

In a formula, pantolactone is mostly there to support a skin-conditioning feel. It blends easily into water-based products like cleansers, moisturizers and makeup removers. Most people will notice it only as part of a smooth, comfortable texture, not as a separate sensation on the skin.

Frequently asked questions

Is pantolactone the same as panthenol?

No. They are related, but not the same. Pantolactone is a building block used to make panthenol, the vitamin B5 derivative you may see more often on labels. Pantolactone is listed on its own when it is in a product.

Does pantolactone stay on the skin?

It depends on the product it is in. In cleansers and makeup removers it is rinsed or wiped away. In moisturizers it stays on the skin. Follow the directions on the label for each product.
