If your skin is feeling dry, tight or a little irritated, panthenol is the comforting multitasker your routine needs. Also known as pro-vitamin B5, it binds water to your skin to keep essential moisture locked in, while helping to soothe the look of redness and irritation and support a healthy-looking, resilient skin barrier. It's generally gentle enough for even sensitive skin, which is why K-beauty brands like SOME BY MI, PURITO and NUMBUZIN have built entire soothing ranges around it. Our edit brings together the best panthenol toners, serums, creams and cleansers from the K-beauty world, for calm, comfortable, happy skin.
