The Ordinary 100% Plant-Derived Squalane For superdry skin, squalane oil really seeps in to both instantly moisturise and also to limit the ongoing loss of hydration later. The Ordinary's 100% Plant-Derived Squalane ($8) is a popular facial oil that keeps skin soft and supple whether applied all over or targeted on problem spots only. (It's earned a 4.6-star rating from other Sephora shoppers, too.) Image Source: sephora.com 100% Plant-Derived Squalane $8 from sephora.com Buy Now
