Born from Kose's DECORTÉ labs in Tokyo, this serum was created for those who feel their lips have lost their youthful fullness due to modern life, stress, and environmental factors. Our researchers identified a key barrier to lip hydration and developed a targeted formula to address it, selecting ingredients backed by 7 clinical trials. Every batch is produced in a Japanese GMP-certified facility, ensuring pharmaceutical-grade purity and consistency. It's not just a lip product; it's a precision treatment, now a top-ranked choice in Japan for those seeking visibly fuller, smoother lips without invasive procedures.

The Kose DECORTE Plumping Lip Serum - Hydrating Treatment for Fuller Lips is formulated with a blend of key ingredients designed to enhance lip volume, hydration, and overall health. Hyaluronic acid is included for its exceptional moisture-retention properties, attracting and binding water to the lips to combat dryness and create a plumping effect by filling fine lines. Peptides, such as palmitoyl tripeptide-1, are incorporated to stimulate collagen production, which helps improve lip firmness and elasticity over time, contributing to a fuller appearance. Ceramides are added to reinforce the skin barrier, preventing moisture loss and protecting against environmental stressors. Botanical extracts like rosehip oil and shea butter provide nourishing fatty acids and antioxidants, soothing and softening the lips while promoting a smoother texture. Additionally, vitamin E acts as an antioxidant to neutralize free radicals and support skin repair. Together, these ingredients work synergistically to deliver intense hydration, enhance lip volume, and improve overall lip condition, making it an effective treatment for achieving fuller, healthier-looking lips.
