Welcome to I'm Obsessed, a daily video series with Kahlana Barfield, InStyle's fashion and beauty editor at large. Check back every weekday to learn more about the beauty products and tools she can't get enough of.
Even our favorite beauty essentials can sometimes use a little boost. Cue Cover FX’s Custom Infusion Drops, an oil-free, hydrating serum that seamlessly blends into moisturizer, oil, primer, or foundation for an extra source of vitamin concentrate and transformative results. Made with a formula that contains sodium hyaluronate, the drops can be used to calm irritated skin, prevent rapid aging, hydrate, and brighten. Available in four mixtures (chamomile, jasmine, neroli, and lemongrass), these are also super simple to dab on.
Shop it: $48; sephora.com.
