Just like hyaluronic acid, vitamin B5 — or panthenol, as you might see it on various ingredients lists — is a humectant, which means it too attracts moisture. The difference? It also keeps that moisture under lock and key in the skin. “When used together, vitamin B5 and hyaluronic acid work synergistically, with vitamin B5 soothing the skin, reducing redness and inflammation,” adds Dr Ellie Rashid, consultant dermatologist and Klira pro medical director. She explains that vitamin B5 can also improve uneven skin texture and regulate oil production, making it great for those with oily, acne-prone skin. But both vitamin B5 and hyaluronic acid are so gentle, they can be tolerated by those with sensitive and reactive skin, too.
