  • Daytime Moisturizer

    Wu says there are two key characteristics that separate day from nighttime moisturizers. “Daytime moisturizers have SPF to protect you from UV rays when you’re walking around outside,” she says. “They also tend to be more lightweight, so you can put makeup on without feeling greasy or looking shiny.”

    Other than being richer and not containing SPF, Wu says nighttime moisturizers may include ingredients like retinoids (to plump) and glycolic acid (to polish)—these are usually exclusive to night formulas because they can make your skin sensitive to the sun.

  • Do You Really Need Both?

    Simply put, yes. “It’s a good idea to wear a product with SPF during the day if you’re going to be outside, or even if you’re indoors but near a window with sunlight streaming through,” says Wu. “Many of my patients prefer using different products for day and night because they want the benefits of different ingredients. For example, someone might choose to use an antioxidant moisturizer in the morning and a product with retinoids at night.”

    Wearing a moisturizer with SPF during the day will also help prevent dark spots and skin discoloration, as well as slow down the development of wrinkles. Aesthetic reasons aside, SPF also has another important purpose: protecting you from skin cancer.

  • If You Had to Choose Just One…

    Wu says that if you’re adamant about having just one type of moisturizer, choose a moisturizer with SPF for both day and night: “There’s no harm in using SPF at night!”

    Do you use a separate moisturizer for day and night? Tell us in the comments!

     

We expect our moisturizers to do quite a lot for us: hydrate, brighten, soothe, mattify, plump, smooth, tighten…the list goes on. When it comes to the difference between our AM and PM lotions, however, we hesitate. Sure, the benefits they promise sound appealing, but is it really necessary to have two (or three, or four…) different types if one can do the job just as well? We spoke with Los Angeles dermatologist Dr. Jessica Wu and asked her stance on the great moisturizer debate.
