The collection centers on a 5 Peptide Complex designed to treat skin rather than simply provide surface-level shine. By incorporating ingredients like Panthenol, Hyaluronic Acid, and Squalane, the brand aims to address the needs of consumers who view lip care as an extension of their daily facial regimen. This shift toward skinification in beauty products is reflected in the product formats: a tinted treatment for daily wear, a restorative salve for barrier repair, and an intensive overnight mask.
The Product Range
The 5 Peptide Collagen Lip Fill Tinted Treatment serves as the collection's hero, offering seven buildable shades ranging from Strawberry to Cocoa. Priced at $16, it aims to provide a plumped appearance without the tackiness typically associated with traditional glosses. For deeper restoration, the 5 Peptide B5 Barrier Repair Salve Lip Balm and the 5 Peptide Ceramide Barrier Comfort Lip Mask, both retailing at $15, utilize Shea Butter and Murumuru Seed Butter to condition sensitive or dehydrated skin. The launch, which went live on Ulta.com on September 6, 2026, marks a significant expansion for COSRX as it moves beyond traditional face care into versatile, treatment-oriented cosmetics.
