      I don't want to start this article on a panic note, but Amazon Prime Big Deal Days concludes tonight. The two-day event, which kicked off on October 7 for Amazon Prime subscribers, features countless deals across various categories—fashion, beauty, home, you name it!—and by midnight, the discounts will officially disappear. Brace yourself for a scrolling spree. While it may just be a small moment in our fall schedules, for aware beauty shoppers, sorting through the extensive discounts feels like a full-time job (and for this beauty editor, it literally is). Great news: I’ve tested a significant portion of the products on offer (it’s part of my job!), and compiled a curated list of items that genuinely deserve the buzz. Scroll down to replenish your favorite products or find a new essential—just hurry before they (or the sales) vanish.

      Quick Highlights:

      The Product I Stand By for Liquid Hair: dpHUE Glossy Glaze, Sheer ($29) ($22)

      The French Pharmacy Essential: Embryolisse Lait-Crème Concentré ($29) ($23)

      The Microcurrent Tool That Surprised Me With Its Discount: NuFace Mini+ Microcurrent Facial Device Kit ($250) ($175)

      The Trending Setting Powder That Provides a Real-Life Filter: Laneige Neo Blurring Powder ($25) ($18)

      The Vitamin C Serum Favored by Hailey Bieber: BeautyStat Universal C Refiner ($62) ($31)

      Haircare

      dpHUE Glossy Glaze, Sheer

      It only takes two minutes for this sheer glaze to completely change your hair. The brand likens it to lip gloss for hair, giving a shiny, well-hydrated sheen that lasts through several washes. It's my go-to for achieving glass-like, "liquid" hair, so I'm definitely taking advantage of the 25% discount.

      IGK Good Behavior Spirulina Protein Smoothing Spray

      This smoothing blowout mist is as close as you can get to an at-home keratin treatment substitute. It contains advanced, heat-activated bonding polymers that wrap around the hair shaft (reducing frizz) and infuses spirulina protein to strengthen strands. For my frizz-prone wavy-curly hair, it’s an absolute lifesaver.

      VEGAMOUR Gro+ Advanced Hair Serum

      In my opinion, this is one of the few hair growth serums that makes a real difference. You need to use it consistently (daily for three months), but I've seen new baby hairs sprouting around my sparse temples over time. I go through bottles quickly, so this 30% off offer is really appealing.

      I would buy this hair oil just for its creamy coconut and yuzu-infused fragrance, but it also leaves my hair incredibly soft and shiny. I apply it before bed, focusing on the ends, and somehow wake up with no split ends or tangles. It feels like magic!

      Skincare

      SK-II Facial Treatment Masks (10 Count)

      Yes, they are expensive, but they are absolutely worth it. SK-II sheet masks are my ultimate treat-yourself purchase. I rarely use the term poreless (since everyone has pores!), but my skin genuinely looks poreless after soaking with this serum-infused sheet for 20 minutes. Celebrity makeup artists swear by them too for red carpet prep, just in case you need more persuasion to grab a pack of ten.

      Obagi Medical ElastiDerm Lift Up & Sculpt Facial Moisturizer

      This moisturizer has been clinically proven to visibly lift and sculpt the face in just six weeks (yes, really). You should see the incredible before and after images—it’s astonishing. It’s also intensely hydrating with polyglutamic acid (a peptide also found in dermal fillers) without leaving my skin greasy. A true story: I recently convinced a friend to try it, and she’s since restocked three times, saying she "can’t live without it."

      Sulwhasoo First Care Activating Sheet Mask (5 Count)

      Can you tell that I’m a fan of good sheet masks? This pack from Sulwhasoo is a must-have, infused with three weeks' worth of the brand’s First Care Activating Serum, which includes ginseng fermented for over 500 hours—and it’s currently 30% off! WWW’s beauty director Erin Jahns is also a big fan of Sulwhasoo masks, mentioning that her skin has "never looked so hydrated, bouncy, and dewy."

      ma:nyo Pure Cleansing Oil (2 Pack)

      I tried this on a whim when I needed a new oil cleanser just before a weekend getaway. Now, I genuinely can't imagine my routine without it. The silky oil dissolves stubborn makeup and sunscreen effortlessly without feeling too heavy, leaving a dewy, healthy-looking finish. It’s easy to see why it’s known as Korea’s top cleansing oil!

      Embryolisse Lait
