We’ve never been able to fully understand how moisturizers with SPF work. As a rule, sunscreen is meant to sit on the skin to act as a defense between your face and the sun. It’s generally not meant to penetrate the skin, because it’s supposed to block out all those harmful UV rays. Moisturizers, on the other hand, are the opposite; their very purpose is to penetrate the skin, adding moisture that wasn’t already there.

So what gives? How can a product that blends the two work well on either front (i.e., protect your skin from the sun and properly moisturize it?). And considering that, how is it that there are thousands of moisturizers with SPF on the market? We let the experts break it down for us.

Keep reading to learn whether moisturizers with SPF are actually effective, and see some top picks from the experts, below.

How Sunscreen and Moisturizers Work

“Sunscreen is not an ingredient,” asserts Haslacher. “It should be treated as a very important layer in your skincare routine and should always be applied last (but before makeup). The purpose of sunscreen is to form a protective film on top of the skin to shield it—SPF is not there to restore moisture balance or deliver ingredients deeper into the skin.”

“Sunscreen is regulated by the FDA as a drug,” she continues, “and those regulations require a specific amount of SPF in order for it to be effective, leaving little room for other active ingredients in a formula. Most importantly, when exposed to air and light, sunscreen becomes ineffective after a short period of time (about 90 minutes max). You need to reapply it if your skin is exposed to the sun.”

Similarly, Greenfield doesn’t recommend combining the two products; however, she has a different view on it. “Although moisturizers penetrate the skin, they only get past the very top layer, which pretty much still stays on top of the skin, just like a sunscreen would.” She continues, “Because although it may say SPF 15 or 30 on the label, the amount you put on your face will not be enough to get that much coverage, and it will be diluted out by the moisturizer. So, you will only have an SPF of 10 to 12 in effect on your skin. The best way to apply is to put on moisturizer first, then apply an SPF 30 or more each morning at least 15 minutes prior to sun exposure.”

Are SPF Moisturizers as Effective as Sunscreen?

While experts recommend using both a moisturizer and a separate sunscreen, the reasoning comes from more than just the products’ ability to penetrate your skin. Instead, it’s about the sunscreen’s ability to fully live up to its SPF number, as mixing it with other ingredients may dilute the formula. That, and the fact that you’re technically supposed to continually apply sunscreen throughout the day (which you may not want to do with your moisturizer, based on your skin type or the product’s price).

Still, while it’s not exactly derm-recommended, applying a moisturizer with SPF is better than applying no SPF at all. But because we want the best for you, dear readers, here are our favorite moisturizers and SPF options (separately).

This is the perfect sunscreen for people who do not at all like sunscreen. It’s made to be worn under makeup, so it goes on super thin (shake it first), but it’s high enough SPF to keep you from burning. It’s also formulated so as to not cause acne or irritate your skin, so if that’s been keeping you from your SPF, it shouldn’t now.

The Final Takeaway

So there you have it. Sunscreen is its own layer of skin protection and shouldn’t be added to a moisturizer. Combining both products can dilute the formulas, and by keeping them separate, you’ll reap the full benefits of your SPF and moisturizer.
