After all, how involved can a superstar juggling myriad projects be? Especially someone as busy as Jennifer Lopez. Yet according to fans, her skincare line's newest exfoliant is just as hard-working as the star herself. The proof is in its popularity: The That Overnight Hustler AHA + BHA Resurfacer sold out after launching last month, the brand tells InStyle, and promptly racked up a 3,500-person waitlist on JLo Beauty's website. While it's still MIA there, Sephora has it in stock — and per people who've tried the overnight treatment, no product has made their skin look smoother, clearer, or more even. As one person on the cusp of 50 said, it's their favorite nighttime addition for addressing "fine lines, sagging skin, and uneven tone." The combination of plumping hyaluronic acid and line-softening lactic and glycolic acid leaves wrinkles less visible after a couple applications, a different person agreed, writing that they're "amazed at the difference" it made in just a few nights.

On top of those, willow bark extract clears pores, and bromelain adds a last exfoliating angle — so it's no wonder Sephora reviewers see much smoother skin and a J.Lo-worthy glow. "This has absolutely changed my skin," one user wrote of the "relaxed, fresh" skin they saw upon waking. The Face Cream Jennifer Lopez Used for Years Is Currently on Rare Sale Those with chronically dull skin were also satisfied by the amped-up brightness it delivered, like one customer who noted that it softened their fine lines as a bonus. Dark spots lighten too, a logical consequence of the Resurfacer's acid squad — but as multiple people addressed, the "liquid gold" somehow still feels gentle. If you'd like to try the J.Lo-created exfoliant that leaves skin feeling "soft and new," skip the waitlist and get the That Overnight Hustler AHA + BHA Resurfacer for $58 at Sephora.
