Congrats! You've made it to Q4, and one of our favorite ways to celebrate is to stock up on the fall and winter beauty essentials now, while hefty sales are happening now. 

For October Prime Day, the star-loved Korean beauty brand Medicube (whose celeb fans include Kylie Jenner, Kyle Richards, Gia Giudice, and many more) has added some of its bestselling products and devices to its blow-out sale on Amazon, happening now—including its viral Zero Pore Toner Pads, the secret to flawless glass skin in winter, now 35% off.

Glass skin gets considerably harder to fake once fall and winter arrive—but Medicube’s viral Zero Pore Pads is the single step we (and countless stars, too) love to use since the prep is refreshingly low-lift.

The Korean skincare essential has a long list of celebrity fans and it’s also backed by thousands of five-star ratings from shoppers who reach for the one-step pads to help smooth texture, tackle congestion, and get brighter-looking skin.

The step that takes just seconds is now 35% off: the dual-textured pads use lactic acid (AHA), salicylic acid (BHA), and white willow bark to exfoliate, removing dead skin cells, clearing excess oil, and thus reducing the look of clogged pores and rough texture. 

The pre-soaked toner pads are especially handy when your routine needs a reset. Simply swipe the dual-textured pad over clean skin: The textured side gently exfoliates away excess oil and buildup (great for dry, cracked lips, too), while the smooth side refreshes skin before the rest of your routine.

Formulated with AHA and BHA exfoliants, the pore pads help minimize the look of pores, clear away sebum, and smooth the look of rough texture. That makes them a perfect makeup-prep step, whether you’re dealing with lingering post-summer breakouts or simply want your foundation to apply more evenly. 

Making these part of your daily routine, especially if you're not currently using toners in your regimen, will definitely show you some type of improvement, as long as you use them correctly - find out how, ahead. 

After cleansing or washing your face, on clean skin, use the embossed side to exfoliate, gently sweep from the center of your face outward. Focus on areas that tend to get oily or textured, like your T-zone, chin, and around your nose—just avoid the eye area.

Then, flip the pad over and use the silky side for a final smoothing pass. Lightly pat in the remaining essence before following with your serum, moisturizer, and SPF in the morning.

The pads are gentle enough for daily use, morning or night, but sensitive skin types may want to start with just a couple times per week to build up a tolerance to the AHAs and BHAs. If sensitive skin reacts strongly, Medicube makes a gentler version that works just as well, with the same deal on Medicube's Toner Pads Zero Pore Pad Mild 2.0 for Gentle Exfoliating for the same price.

Now 69% off, this "tingling" liquid skin booster pairs exfoliating AHAs, BHAs, and PHAs with 2,000 ppm of exosome-coated spicules to smooth texture, brighten dull skin, and refine the look of pores. The beginner-friendly strength is ideal for easing into the viral liquid-microneedling trend.

Give your neck-care routine a major upgrade with this PDRN and Volufiline-infused cream, complete with a built-in gua sha applicator, now half-priced. Glide it across the jawline, neck, and décolleté to hydrate, depuff, and leave skin looking smoother and firmer.
