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.

“The Tripeptide Plumping Lip Balm has completely changed my mind on lip plumping products! I have seen a pretty noticeable change in my lip volume. I even caught myself in the mirror the other day and couldn't believe how plump my lips looked. I love that there is no tingling sensation and my lips are feeling so hydrated and moisturized. And from someone that suffers from dry lips, this is a complete gamechanger!”- @‌megceline_

    Awesome but needs a different delivery system - different packaging

    I love this lip balm, I've been using it since it first came out. I'm forever talking about it to whomever will listen, no joke. That said, I've bought about a dozen tubes and as I'm not one to waste any drop of product, I'll cut open the tubes when I can't get any more to come out. I am amazed at the amount (and consistency) of the product left behind when the tube is cut open. I'm absolutely certain that this would be an even better product if the balm came in a traditional doe foot applicator lip gloss container instead of a tube. It seems the product separates in the tube and the thin liquid comes out first while the thicker "balm" is left behind. I've discovered this with every tube I've cut open. Please consider changing the packaging, and maybe the balm will be more moisturizing with no separation.

    Disappointed

    Used a minimum of 3 times per day. It's really good for moisturising, I like to leave it on overnight and in the morning my lips are really soft , however after 4 weeks of use, sadly there is no change in the size/plumping of my lips
