Dull, Dehydrated Skin? I Don’t Know Her Thanks to This $20 Jelly-Like Serum

This serum contains a mix of super hydrating ingredients, including hyaluronic acid, polyglutamic acid, and snow mushroom extract. 

By now, we’re probably all familiar with hyaluronic acid. It’s a powerful humectant, which means it attracts (and holds) water in the skin, replenishing cell hydration. While very different than hyaluronic acid, polyglutamic acid serves a similar function. It’s a peptide that, according to the brand, can hold up to 4000 times its weight in water. It’s just what your skin needs to look plump, bouncy, and, well, hydrated.
