Glow This Winter: COSRX Reveals Unmissable Deals for Amazon Black Friday & Cyber Monday

LONDON, Nov. 17, 2025 /PRNewswire/ — When it comes to the most anticipated shopping event of the year, nothing rivals Amazon’s Black Friday & Cyber Monday(November 20^th – December 1^st). This season, COSRX, the award-winning K-beauty brand loved by dermatologists and TikTok creators alike, introduces its ultimate repair-and-glow skincare lineup — the perfect prescription to keep skin healthy, hydrated, and radiant all winter long.

Peptides are dominating the beauty conversation — from dermatologist clinics to TikTok trends — solidifying their status as one of this year’s most sought-after ingredients. But why should peptides remain a winter essential? These powerhouse, amino acid chains, help boost collagen, improve elasticity, and lock in hydration, targeting dryness and visible signs of aging that intensify in colder weather.

• (Up to 36% OFF) The Peptide Power You Can’t Miss This Black Friday
  
  
  Infused with six powerful peptides, COSRX’s iconic Peptide Trio delivers visible, all-day glow — a performance proven by thousands of glowing reviews. This Black Friday, shoppers can stock up on ‘The 6 Peptide Skin Booster Serum’, formulated to recharge skin hydration and elasticity with its 150ml value size, and ‘The Peptide Collagen Lifting Glow Hydrogel Mask’, a sheet-free collagen treatment that works overnight for firmer, more luminous skin. Completing the trio, ‘The Peptide Collagen Hydrogel Eye Patch’ — a TikTok-favorite topical glow treatment — targets eye bags, neck lines, and flaky skin, offering instant radiance where you need it most.
  
   
• (Black Friday: Up to 56% OFF) The Snail Solution: Your Winter Hydration Hero
  
  
  Winter is the ultimate stress test for the skin — dryness, sensitivity, and dullness all peak as the temperature drops. In response, COSRX’s iconic Advanced Snail line remains the brand’s best-selling solution for soothing irritation and restoring resilience. The ‘Advanced Snail 96 Mucin Power Essence’ — crowned Amazon UK’s No.1 serum for nine consecutive seasons — features 96% snail secretion filtrate, known to calm irritation, reduce redness, and visibly refine skin texture. When paired with the ‘Advanced Snail 92 All in One Cream’, it delivers long-lasting hydration without heaviness, leaving skin with a supple, glass-skin glow that withstands even the driest winter air.
