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.

    Healthier lips!!

    After receiving this product, I immediately started to test its ability to fill the fine lines of my lips, as promised by the details in the box. I was quite skeptical, but after 2 weeks I started to notice the first ameliorations. The lips look more full and more healthy. The formula is not heavy, on the contrary it feels comfortable during the day. Definitely a good product that I will repurchase once finished! #productofferedbyTheINKEYList

    Nice shine

    Just received this and been using it for a couple days now. Haven’t really seen a difference in lip plumping but it does give good shine.

    Surprising results!

    I love all lip balms and glosses that have the plumping effect. However, I didn't realize that this balm is not the traditional plumping balm. The first time I tried it I was thinking "what the heck, no tingling". But I have been using this for the last week and I have noticed a definite hydration in my lips. Plus, I have not had to constantly reapply. I would have given it 5 stars but the only negative thing is the taste at times. Will definitely buy again!
