What is Panthenol?

Panthenol is a precursor of pantothenic acid (or vitamin B5), a key ingredient in many skincare cosmetics in recent years.


Panthenol is a humectant meaning it holds and binds water, and these properties mean that it is ideal when it comes to keeping water in the skin. It also works as an emollient which means it can moisturize and soothe the skin, as well as help, protect it from environmental factors and skin stresses.

What does panthenol do for the skin?

Panthenol’s molecular structure and chemical properties mean that it is rejuvenating and benefits a number of different skin issues.

Benefits of panthenol

Panthenol makes for a great moisturizing ingredient. Research has shown that it decreases transepidermal water loss (water that evaporates through the skin). Products containing just 1% of panthenol can rapidly hydrate skin, resulting in a more supple feel and appearance.

This means that panthenol is ideal for skin types that are experiencing particularly stressful environmental factors, such as harsh climates, air conditioning, or central heating. Panthenol’s ability to combat transepidermal loss makes it perfect for dealing with the stresses that these types of factors cause. Cetaphil’s panthenol-containing products such as Cetaphil’s Deep Hydration 48 Hour Serum and Cetaphil’s Deep Hydration Healthy Glow Daily Cream are ideal for combatting transepidermal loss or stressful external environments.

Panthenol’s emollient properties help to maintain a healthy skin barrier. Your skin barrier consists of natural oils and lipids that protect your skin from water loss, allergens, and bacteria.
