NEW YORK, Sept. 8, 2026 /PRNewswire/ — Global derma skincare brand COSRX is expanding its Peptide skincare expertise with the launch of the 5 Peptide Lip Collection, a nine-product collection that brings skincare-grade ingredients and targeted care to the everyday lip routine.

Launching exclusively with Ulta Beauty in the U.S., the collection is available online at Ulta.com starting September 6, 2026.

Known for developing accessible, high-performance skincare around active ingredients and specific skin concerns, COSRX is bringing the same philosophy to lips. As skinification continues to expand across beauty, consumers are increasingly looking for skincare-inspired ingredients and targeted benefits in their everyday lip products. After all, lips are skin too and they deserve the same thoughtful care. At the center of the collection is a 5 Peptide Complex, paired with complementary skincare ingredients including Collagen, Panthenol and Ceramides across three treatment-focused formats.

The result is lip care that goes beyond shine and color, targeting concerns such as dryness, rough texture and the appearance of lip lines while delivering the smooth, comfortable textures and easy wear consumers look for in everyday lip products.

The collection includes:

• 5 Peptide Collagen Lip Fill Tinted Treatment — $16, available in seven shades
• 5 Peptide B5 Barrier Repair Salve Lip Balm — $15
• 5 Peptide Ceramide Barrier Comfort Lip Mask — $15

A Skincare-First Take on the Tinted Lip Treatment

The hero of the collection, the 5 Peptide Collagen Lip Fill Tinted Treatment, combines COSRX’s Peptide skincare expertise with sheer, buildable color and a glossy, glazed finish.

Formulated with 5 Multi-Peptides and Collagen, the treatment is designed to help visibly smooth the look of lip lines and leave lips appearing fuller and plumper. Ceramide, Hyaluronic Acid and Squalane complement the formula to help keep lips feeling soft and hydrated.

Rather than behaving like a traditional sticky gloss, the buttery formula coats the lips in high shine while remaining lightweight and comfortable to wear.

The seven shades range from fresh pink and peach tones to deeper cherry, cinnamon and cocoa hues, with sheer-to-buildable coverage that allows color to be layered and intensified to suit the desired look. Shades include 01 Strawberry, 02 Sour Berry Jelly, 03 Peach, 04 Cherry, 05 Cinnamon, 06 Cocoa and 07 Black Cherry.

Early reviews from COSRX consumers have highlighted the balance between treatment benefits and cosmetic payoff.

“The consistency is so nice and moisturizing… it made my lips so shiny and voluminous, without the stickiness,” one reviewer shared on COSRX.com, calling the launch “another winner by COSRX.“

That treatment-first approach also resonated with one reviewer who works as a flight attendant and regularly deals with dry, dehydrated lips from long hours in cabin air. She described the formula as feeling “more like a lip treatment than just another gloss,” adding that her lips felt “hydrated, comfortable, and glossy without feeling heavy.”

From Daily Hydration to Overnight Barrier Care

Rounding out the collection are two formulas designed specifically for dry and sensitive lips.

The 5 Peptide B5 Barrier Repair Salve Lip Balm pairs the 5 Peptide Complex with 5% Panthenol (Vitamin B5) and Shea Butter to provide rich hydration and care for dry, sensitive lips. Despite its nourishing salve texture, the formula glides on smoothly without leaving lips feeling heavy or overly sticky, making it suitable for repeated use throughout the day.

For more intensive care, the 5 Peptide Ceramide Barrier Comfort Lip Mask combines Peptides with Ceramide, Shea Butter, Murumuru Seed Butter and Vitamin E to condition dry, rough and flaky lips overnight.

The leave-on treatment can also be used as a conditioning step before other lip products, while its tube packaging offers a convenient alternative to traditional pot-format lip masks.

Together, the three formats create a streamlined lip care wardrobe: daily hydration and barrier support, intensive overnight conditioning, and Peptide-powered tinted treatment for color, shine and visibly plumper-looking lips.

With the 5 Peptide Lip Collection, COSRX continues to expand the role of skincare beyond the traditional face routine, bringing familiar skincare ingredients into a lip category increasingly shaped by consumers looking for both beautiful color and targeted care.
