Whether you’re celebrating outdoors with a Fourth of July BBQ (like Eva Longoria) or heading out to see some epic fireworks, you’ll want to make sure your skin is protected from the sun’s harmful UVs with plenty of sunblock.

But not all SPF is created equal — in fact, there are three different types — and choosing the best one from drugstore shelves can be a daunting task. Unless you just so happen to be Lauren Conrad, that is. The 31-year-old mommy-to-be has a new go-to that she’s wild about, and it’s actually (gasp!) under $10.

When it comes time to hit the beach, LC says it’s Alba Botanica Hawaiian Sunscreen With SPF 45 ($9) that she’s lathering up with. “There’s a huge pump of it in my bathroom,” she told Well & Good.

It’s a wise choice for the pregnant reality alum, as not only is its green tea and aloe inclusive formula 100 percent vegetarian, but it’s lightweight, stays water-resistant for up to 80 minutes, and reportedly dries in a flash. Those that care about the environment (read: all of us) will also be pleased to know that it’s biodegradable and free of animal testing.

In short? It’s the perfect product for those carefree beach days (like today), when you’re hanging poolside in a bandeau (Conrad’s fave, since it won’t give you tan lines) and a caftan, LC-style. “There’s just something glamorous about a lightweight caftan,” she told the outlet.

Looking good, mamma!
