NEW YORK, July 10, 2025 /PRNewswire/ -- As Amazon Prime Day comes to a close, COSRX, the award-winning K-beauty brand trusted by millions, is celebrating a major milestone – multiple Amazon's Choice badges and No. 1 rankings across numerous categories. From high-performance haircare to skin transforming masks, signature essences and invisible sun protection, COSRX products have claimed top titles, cementing their status as must-haves this Amazon Prime Day. With just one day left before the deals expire, now is the time to stock up on these customer favorites.

The COSRX Picks Amazon Customers Can't Get Enough Of

The Amazon's Choice badge is awarded by Amazon based on factors that matter most to shoppers - like product ratings, competitive pricing, availability, and fast shipping. Products with this badge are frequently purchased, rarely returned, and consistently rated high by customers.

This Prime Day, four of COSRX's latest innovations across skincare and haircare have earned this seal of approval:

• COSRX PEPTIDE-132 Ultra Perfect Hair Bonding Treatment
  A salon-grade bond-repair treatment powered by patented PEPTIDE-132, this formula repairs damaged hair from the inside out. The luxurious cream texture melts into strands, sealing in moisture and restoring smoothness, elasticity, and shine. Ideal for all levels of hair damage, heat-styled or color-treated hair, and those needing a weekly hair rescue ritual. Now crowned with an Amazon's Choice badge and ranked no.1 in the New Release Deep Hair Conditioner category, it's a must-have for anyone looking to revive stressed-out strands.
    
• COSRX PEPTIDE-132 Ultra Perfect Hair Bonding Oil Serum
  Bond-strengthening hair oil for glazed, frizz-free shine. Lightweight yet deeply nourishing, this oil-serum hybrid coats each strand with botanical oils and PEPTIDE-132, smoothing frizz and fly-aways without any greasy residue. It delivers a glass finish for hair that looks and feels silky, glossy, and healthy. Ideal for dull, frizzy, brittle hair in need of daily shine and long-lasting protection. Now proudly wearing an Amazon's Choice badge and ranked no. 1 in Amazon's New Release Styling Serums category, it's quickly becoming a go-to for glossy, healthy-looking hair.
    
• COSRX The Peptide Collagen Lifting Glow Hydrogel Mask
  Formulated with six peptides and low-molecular collagen, this premium hydrogel mask visibly firms and hydrates tired skin. As the mask turns transparent, it melts active ingredients deep into the skin, targeting fine lines, texture, and dullness in one luxurious step. Ideal for anti-aging, skin firming, glow enhancement, and all-in-one care for sensitive or mature skin.
    
• COSRX Airy-Light Clear Sunscreen Stick SPF 50
  Weightless, invisible protection that goes where you go. Meet the K-beauty sunscreen that's storming the sun protection bestseller charts for good reason. This clear, no-white-cast SPF stick delivers broad-spectrum protection with a soft, non-greasy finish. Waterproof and sweat-resistant, it's perfect for reapplying on the go - all summer long. Ideal for oily or sensitive skin, outdoor activities, and anyone looking for convenient daily sun defense.

Other Award Winners You Shouldn't Sleep On

Also not to be missed - the Advanced Snail 96 Mucin Power Essence, a viral sensation that continues to top the charts. Ranked No. 1 once again this year in Amazon's Facial Serums category, this cult-favorite has captivated millions with its powerful skin-repairing and glow-boosting benefits. Beloved across TikTok and trusted by beauty lovers worldwide, it's now available at its lowest price of 2025 - only during Prime Day. Run don't walk to take advantage of this limited time deal.
