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 fragrance-free 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 2% 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 for 4 weeks.

Unlike some traditional cosmetic lip plumpers, this multi-tasking lip plumper works to maintain the skin barrier and retain moisture to improve and protect overall lip health whilst visibly enhancing lip volume. The clear lip plumping balm leaves a natural sheen on the lips which can be worn alone or over lip color for a glossy finish. 

Suitable for everyone, especially those looking to improve fullness and/or dry, cracked and damaged lips. 

Delivered by science, not irritation, the future of fuller lips has arrived.​

Reviews Summary
Customers say this lip balm delivers mixed results for hydration, with some finding it deeply moisturizing while others report dryness. Many reviews mention a glossy finish and temporary plumping effect, particularly when used consistently. Common feedback includes concerns about the texture, with some noting graininess or clumps. While several users praise its overnight results, others point out the formula's quick wear-off time. Reviews are divided on the scent and taste, which appears to be a significant factor in user satisfaction.

    Thank you for your feedback, Carolina!

    We're so pleased to hear that you enjoyed the plumping results but sorry that this wasn't quite moisturising enough for your particular needs. Our askINKEY Team are always on hand if you need any further support with this experience 🖤

    Thank you so much for taking the time to share your feedback, G.L.

    We're truly sorry to hear about your disappointing experience with our Tripeptide Plumping Lip Balm. It's particularly troubling to hear that you found the texture grainy and didn't experience any of the plumping effects - this is absolutely not the experience we want any of our customers to have. We take product efficacy and our clinical claims very seriously, and we'd love for you to reach out to our askINKEY Team, as we would greatly appreciate the opportunity to understand your experience further and explore how we can make this right for you 🖤
