Set to be your new lip care obsession, keep one in your handbag and one on your desk to maximize your lip plumping every single day.

Clinically proven to plump lips by up to 40% in 4 weeks*, Tripeptide Plumping Lip Balm hydrates, repairs and plumps lips leaving them looking naturally fuller and healthier. Specially formulated for maximum fullness without any tingle or irritation, the plumping balm works over time to visibly increase lip volume. So now your lips not only look plumper but, ARE plumper. No filter, no filler, just fuller.

Formulated with 6% Tripeptide Complex, to visibly increase lip volume over time for plumper-looking, more defined lips, together with 6% Ultra Filling Spheres which deliver Hyaluronic Acid to the lip to plump, retain moisture and help to fill fine lines, Tripeptide Lip Balm enhances fullness, defines lip contours, and reduces the appearance of fine lines and creasing around the mouth. With continued use, the proof really is in the plump. For best results we recommend using at least 3-times per day.

    It's an ok balm

    The texture is a bit too liquid, doesn't stay on for too long, have to reapply frequently.

    Will be re-ordering

    I am a senior, although I don't have dry lips, I was hoping this product would help them look a bit fuller. I think it might. I am happy enough after using it for 4 months, that I will be re-ordering it. It seems to help keep the colour in my lips as well as making them very soft.

    Not for me

    I love the feeling of the product. I actually saw plumping results! I was excited! However, I found that my lips would chap after an hour or so. No amount of application afterward softens my lips. So I end up biting off the rough parts of my lips. Eventually I had to stop using it.

    Thank you for sharing your feedback with us, we appreciate you taking the time to provide insights into your experience with our lip plumping product. We're delighted to hear that you initially enjoyed the plumping results and formula texture. However, we understand your disappointment upon encountering dryness and chapping shortly after application, which ultimately led to an unpleasant experience. While our intention is to enhance lip volume and hydration, we recognize that every individual's skin can respond differently to certain formulations. If you would like further guidance, our askINKEY Team would be delighted to assist you 🖤
