Panthenol

Skin Conditioning

Panthenol is a common ingredient that helps hydrate and soothe the skin. It is found naturally in our skin and hair.

There are two forms of panthenol: D and L.

D-panthenol is also known as dexpanthenol. Most cosmetics use dexpanthenol or a mixture of D and L-panthenol.

Panthenol is famous due to its ability to go deeper into the skin's layers. Using this ingredient has numerous pros (and no cons):

Like hyaluronic acid, panthenol is a humectant. Humectants are able to bind and hold large amounts of water to keep skin hydrated.

This ingredient works well for wound healing. It works by increasing tissue in the wound and helps close open wounds.

Once oxidized, panthenol converts to pantothenic acid. Panthothenic acid is found in all living cells.

This ingredient is also referred to as pro-vitamin B5.

this snail mucin essence really is one of the best ones out there— it's a holy grail. this product was my very first impression of cosrx, and the short ingredient list is very surprising with how effective it is. i've been using it for about a year now, and it's become a staple in my routine. after my first couple weeks of use, a lot of my dark spots disappeared and calmed down my hormonal acne & Show more

This ruined my face! I didn’t know that my dust mite allergy also made me allergic to this. I used it for five months and everything seemed fine, but then I started to get a goatee of fungal acne with big red patches. I’d also been getting a lot of big pimples in my hairline from it. It’s taken me months to understand what happened and to soothe my sad skin. Be warned not to jump off the bridge Show more
