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.

2x Tripeptide Plumping Lip Balm (10ml).

    It's ok

    Good lip gloss. A bit drying, but it works well if you keep your lips hydrated and maybe layer it on some lip balm. Didn't see a change in my lip size.

    Definitely not pluming or hydrating

    I love my Inkey list skincare, so was excited to add this to my regimen. However, I have only noticed my lips have been becoming tight, sore and incredibly dry. Almost like they are sunburnt! I wondered if this lip product had retinol, which was giving me this dry side affect? Sorry, but not a fan of this product for me.
