When it comes to a quality skin care regimen, moisturizers are the one product in your beauty arsenal that doesn't require an introduction. While you're probably familiar with hydrating ingredients like hyaluronic acid and vitamin C at this point, there's another, more underrated inclusion you may not know as well. Enter: vitamin B5, also known as pantothenic acid.

While this active ingredient is fairly new to the skin care game, many experts agree this water-soluble vitamin is essential to smooth out your skin. Shop TODAY interviewed dermatologists about the benefits of pantothenic acid, how to use it and why is a key vitamin for your skin.

What is pantothenic acid?

Pantothenic acid is a water-soluble vitamin that acts as a hydrator to attract water to the skin to make it look more supple. "We all know that hyaluronic acid is [naturally] found in our skin, and as we age, we lose [it]," mentioned Arkansas-based dermatologist Dr. Sandra Johnson. "That is why we as dermatologists inject hyaluronic acid fillers into the skin and apply [it] to our faces in serums. [Vitamin] B5 helps our hyaluronic acid to attract and hold more water, so our skin looks more hydrated and supple."

"It is [also] known as a calming ingredient and I recommend it to all my patients, but especially those dealing with dry skin or irritation," added dermatologist Dr. Ted Lain.

Benefits of pantothenic acid for skin

Pantothenic acid is best known for its hydrating, soothing and moisturizing abilities. It also helps repair a damaged skin barrier thanks to its anti-inflammatory properties. "If your skin is dehydrated, it is more likely to look dull as well as get little cuts/fissures that will allow irritants and infection into the skin," added Johnson.

According to new research, pantothenic acid can be used on the skin to relieve itchiness and promote healing from skin conditions such as eczema, diaper rash, poison ivy and insect bites. "Dehydrated skin can lead to a broken skin barrier, which can lead to inflammation, and as a result, it can lead to a more rapid onset of aging. When you calm dry irritated skin and soothe it, it will oxidate stressed skin and allow the skin to repair faster," said board-certified dermatologist Dr. Shereene Idriss.

Another great thing about this multifunctional ingredient is that it can be used on all skin types. Sensitive skins will see the best benefits with pantothenic acid as it will help your natural hyaluronic acid the most. "Vitamin B5 can be mixed with almost any other ingredient in your skin care regimen," added Johnson.
