New York – September 11, 2026 -- COSRX has launched a nine-product 5 Peptide Lip Collection exclusively with Ulta Beauty in the U.S., available online at Ulta.com starting September 6, 2026.
Three products anchor the lineup with prices from $15 to $16
The collection includes the 5 Peptide Collagen Lip Fill Tinted Treatment at $16, available in seven shades, alongside the 5 Peptide B5 Barrier Repair Salve Lip Balm and the 5 Peptide Ceramide Barrier Comfort Lip Mask, each priced at $15.
A 5 Peptide Complex anchors every formula in the range
COSRX built the collection around a 5 Peptide Complex combined with Collagen, Panthenol and Ceramides. The brand says the formulas target dryness, rough texture and the appearance of lip lines while maintaining smooth, comfortable wear.
The tinted treatment offers seven shades with buildable coverage
The hero product, the 5 Peptide Collagen Lip Fill Tinted Treatment, combines 5 Multi-Peptides and Collagen with Ceramide, Hyaluronic Acid and Squalane. It is designed to visibly smooth lip lines and create a fuller, plumper appearance with a glossy, glazed finish. Shades range from 01 Strawberry and 03 Peach to 06 Cocoa and 07 Black Cherry.
One COSRX.com reviewer described the formula as leaving lips "shiny and voluminous, without the stickiness," calling it "another winner by COSRX."
Two additional formulas target daily and overnight lip care
The 5 Peptide B5 Barrier Repair Salve Lip Balm pairs the peptide complex with 5% Panthenol and Shea Butter for daily hydration without a heavy or sticky feel. The 5 Peptide Ceramide Barrier Comfort Lip Mask adds Ceramide, Shea Butter, Murumuru Seed Butter and Vitamin E in a tube format designed for overnight conditioning of dry, rough or flaky lips.
The full collection is also available on COSRX.com and the brand's official TikTok Shop.
