    Not for me

    Not a fan of this, I'm afraid. Being a lip balm, you'll inevitably end up 'tasting' it and for me, it's not pleasant. Tried it a few times but ended up ditching it. A real shame as I love everything else Inkey.

    Hi Maddy,

    Thank you for your honest review — and for being such a fan of INKEY! It genuinely means a lot to us, even when a particular product isn't quite the one for you.

    We're sorry the taste of the Tripeptide Plumping Lip Balm wasn't to your liking. You're right that with a lip product it's almost impossible to avoid noticing it, and taste is such a personal thing — we completely understand it can make or break the experience. It's really valuable feedback, and we'll be sure to pass it along to our team as we continue to develop and improve our formulas.

    Thank you again for the kind words about the rest of the range — we're so glad the rest of your INKEY routine is working beautifully for you, and we hope to keep it that way!

    If there's ever anything we can help with, our team is always here at help@theinkeylist.com.

    It doesn't plump

    Bought two lip balms before my wedding and used them religiously for months to try and get the most benefit before the big day. It's a decent lip balm, feels comfortable but a little drying. I didn't see any short term or long term lip plumping effects sadly, which is the entire selling feature of this balm. Would buy again IF it plumped my lips. I usually like Inkey products, this one was disappointing.

    Hi Talia,

    Thank you for such an honest and detailed review, and congratulations on your wedding! We're so sorry the plumping results didn't come through the way you'd hoped, especially after using it so faithfully in the lead-up to your big day.

    A little context that might help: our Tripeptide Plumping Lip Balm is formulated with peptides rather than tingling agents, so it works to smooth, hydrate, and enhance the natural look of lips gradually and gently — the effect is more subtle and cumulative than the instant "tingle" plumpers, and results can vary from person to person. We completely understand that if plumping is the main thing you're after, a subtler result can feel disappointing, and that's really valuable feedback we'll pass along to our team.

    We're glad you found the texture lovely and comfortable at least. If you'd like to chat with us further about your experience, our team is always here at help@theinkeylist.com and would be happy to help.

    Thank you again for sharing your experience, and for being an INKEY fan — it really means a lot to us.

    Didn’t work for me

    Used this 3x a day religiously for 3weeks and unfortunately no plumping for me. Lovely texture that lasts well on the lips though and I would say it definitely moisturised a little bit. It smells and tastes awful!! Like a plasticky taste which is a shame. Overall disappointing and would only buy again as a lip balm not a plumper.

    Hi Jayne,

    Thank you for being an INKEY List customer and for such a thoughtful, honest review, we really appreciate you sharing your full experience.

    We're so glad to hear you loved the texture and found it moisturizing! We're sorry the plumping results didn't meet your expectations, though. A quick note that might help: our Tripeptide Plumping Lip Balm is formulated with peptides rather than tingling agents, so it works to smooth and enhance the look of lips gradually and gently over time — the effect is more subtle and cumulative than the instant "tingle" plumpers you may have tried. Individual results can also vary from person to person.

    We also appreciate the feedback on the taste, we're always working to improve our formulas, and comments like yours genuinely help.

    If you'd ever like personalized advice on getting the most from the product (or finding the right fit for your lip goals), our team would love to help — just reach out at help@theinkeylist.com.

    Thanks again for giving it a try, and for the kind words on the texture.
