Cosrx Snail Mucin Repairing Serum ($15, originally $25)
If glass skin is your goal, Cosrx's snail mucin essence could be a welcome addition to your routine. The K-beauty favorite is known for its lightweight feel and is loved for helping brighten skin, soothe the look of redness, and hydrate without feeling greasy. One of our editors shares why she loves it in her Cosrx Advanced Snail 96 Mucin Power Essence review.
Editor Quote: "My skin's texture has actually improved, and it feels way more even now. The hydration payoff is also huge, and I feel like it actually helps my moisturizer work better, too. For a while, I had been feeling as though the cream would just sit atop my skin after application, and now I feel like it's actually penetrating through and sinking in. Best of all, I finally feel close to glazed doughnut status." – Kelsey Garcia, lifestyle director
