COSRX launches 5 Peptide Lip Collection

USA – Global derma-skincare brand COSRX has expanded its peptide-led skincare portfolio into the lip category with the launch of the 5 Peptide Lip Collection, its first colour-infused lip skincare hybrid, debuting exclusively at Ulta Beauty. 

The move aligns with the broader “skinification” of beauty, where consumers increasingly expect skincare-grade ingredients and functional benefits in daily-use colour and care products. 

At the core of the range is a 5 Peptide Complex, which COSRX positions as the primary driver of visible smoothing and plumping effects on the lip surface. 

Across the three formats, the complex is paired with complementary barrier and hydration actives including Collagen, Panthenol (Vitamin B5), Ceramides, Hyaluronic Acid, Squalane, Shea Butter, Murumuru Seed Butter and Vitamin E. 

This multi-ingredient architecture is designed to address common lip concerns, dryness, rough texture and the appearance of fine lip lines, while maintaining comfortable, non-sticky wear.

This multi-ingredient architecture is intended to address common lip concerns such as dryness, rough texture and the appearance of fine lip lines while maintaining comfortable, non-sticky wear. 

The line is built around three distinct formats that together form a “lip care wardrobe” for daily maintenance, intensive repair, and tinted treatment: a daily balm, an overnight mask, and a tinted peptide treatment that serves as the collection’s hero product.

The flagship item, the 5 Peptide Collagen Lip Fill Tinted Treatment, combines 5 Multi-Peptides and Collagen to help visibly smooth lip lines and create a fuller-looking lip contour, while Ceramide, Hyaluronic Acid, and Squalane deliver hydration and softness in a buttery, high-shine formula engineered to avoid the tackiness often associated with glosses. 

It is offered in seven sheer-to-buildable shades including 01 Strawberry, 02 Sour Berry Jelly, 03 Peach, 04 Cherry, 05 Cinnamon, 06 Cocoa and 07 Black Cherry, and early user feedback highlighted the balance between treatment benefits and cosmetic payoff, with reviewers describing the texture as moisturizing, shiny and volumizing without stickiness. 

Complementing this is the 5 Peptide B5 Barrier Repair Salve Lip Balm, which pairs the 5 Peptide Complex with 5% Panthenol and Shea Butter for rich, comfortable hydration suited to dry, sensitive lips.

Meanwhile, the 5 Peptide Ceramide Barrier Comfort Lip Mask is an overnight leave-on treatment that combines Peptides with Ceramide, shea butter, murumuru seed butter, and Vitamin E to condition dry, rough and flaky lips in a hygienic tube format that can also be used as a pre-makeup conditioning step.
