      Not to alarm you, but Amazon Prime Big Deal Days concludes tonight. This two-day event, which kicked off on October 7 for Amazon Prime members, features an extensive array of deals across numerous categories—fashion, beauty, home, and more! As the clock strikes midnight, the discounts will be gone. Prepare for a scrolling spree. Although it may seem like a minor event on our fall calendars, for astute beauty shoppers, digging through the multitude of discounts feels like a full-time gig (and for me, as a beauty editor, it literally is). Here’s the good news: I've tried a substantial number of the products currently on sale (it's part of my job!), and I've put together a curated list of items that genuinely deserve the buzz. Keep scrolling to replenish your favorites or find a new essential—just do it quickly before they (or the discounts) vanish.

      Quick Highlights

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

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

      The Microcurrent Device That’s Amazingly on Sale: NuFace Mini+ Microcurrent Facial Device Kit ($250)($175)

      The Trending Setting Powder That Provides a Natural Filter Effect: Laneige Neo Blurring Powder ($25)($18)

      The Vitamin C Serum Adored 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 transform your hair. The brand likens it to lip gloss for your locks, as it delivers a shiny, well-hydrated layer that endures through several washes. It’s my secret to achieving glassy, "liquid" hair, so I'm definitely taking advantage of the 25% discount.

      

      IGK

      Good Behavior Spirulina Protein Smoothing Spray

      I genuinely believe this smoothing mist comes closest to replicating an at-home keratin treatment. It contains advanced, heat-activated bonding polymers that form a protective layer around the hair shaft, helping to reduce frizz, along with spirulina protein that strengthens strands. For my frizz-prone wavy-curly hair, it’s a miracle.

      VEGAMOUR

      Gro+ Advanced Hair Serum

      This is one of the few hair growth serums that I believe makes a visible impact. Consistency is key (using it daily for three months), but I’ve noticed new baby hairs around my thinning temples over time. I go through bottles quickly, so this 30% off deal is quite tempting.

      I would purchase this hair oil just for its delightful creamy coconut and yuzu-infused scent, but it also leaves my hair incredibly soft and shiny. I apply it before bed, concentrating on the ends, and somehow awaken with no split ends or tangles. Pure magic!

      Skincare

      SK-II

      Facial Treatment Masks (10 Count)

      Yes, they are pricey, but they are absolutely worth it. SK-II sheet masks are my ultimate indulgence. I rarely use the term poreless (because every human has pores!), but that's exactly how my skin looks after soaking in this serum-loaded sheet for 20 minutes. Celebrity makeup artists also swear by them for red carpet prep, which may further persuade you to grab a pack of ten.

      Obagi Medical

      ElastiDerm Lift Up & Sculpt Facial Moisturizer

      This moisturizer has been clinically proven to visibly lift and shape the face in just six weeks (yes, really), and the before-and-after photos are astonishing. Additionally, it is deeply hydrating due to the polyglutamic acid (a peptide also found in dermal fillers) without leaving my skin feeling greasy. A friend I recommended it to recently restocked three times, saying she "can't live without it."

      Sulwhasoo

      First Care Activating Sheet Mask (5 Count)

      Can you tell I’m fond of sheet masks? This Sulwhasoo pack is a no-brainer, infused with three weeks’ worth of the brand's First Care Activating Serum, which contains ginseng that has been fermented for over 500 hours—and it’s currently 30% off! WWW beauty director Erin Jahns also claims to be a huge fan of Sulwhasoo masks, stating her skin has never been so hydrated, bouncy, and dewy.

      Pure Cleansing Oil (2 Pack)

      I randomly tried this when I needed a new oil cleanser just before a weekend trip, and now I can't envision my routine without it. This silky oil effortlessly dissolves stubborn makeup and sunscreen without feeling heavy, and it leaves a dewy, healthy sheen. I understand why it’s considered Korea’s top cleansing oil!

      Embryolisse

      Lait-Crème Concentré
