Before results

“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_

Reviews Summary
Customers say this lip balm delivers mixed results for hydration and plumping effects. Many appreciate its moisturizing qualities and subtle plumping when used consistently, especially overnight. While some report smoother, fuller-looking lips, others find it basic or ineffective. Common feedback includes concerns about the texture, with some noting grainy bits, and divided opinions on its lasting power. The taste and smell receive frequent mentions as drawbacks. Regular users often keep multiple tubes and report best results with consistent application throughout the day.

    That’s very nice on the lips

    Not sure if this is actually pumped, but I have been using this daily moisturise my lips and it doesn’t feel slimy after use. I do prefer the tinted one that I have.

    A good back up

    My lips get very dry and unfortunately this doesn't penetrate them deeply enough, feels quite surface. No plumping has been obvious.

    Hi there,

    Thank you for taking the time to share your honest feedback about our Tripeptide Plumping Lip Balm. We're sorry to hear that it's not providing the deep hydration your dry lips need and that you're finding it feels more surface-level rather than penetrating effectively.

    We understand how disappointing it must be when you're dealing with very dry lips and hoping for a product that will provide that deeper, more intensive moisture you're looking for. We also recognise that you haven't experienced the plumping effects you were expecting, which adds to the frustration when the product isn't delivering on the key benefits you were hoping to see.

    While this formula works well for many customers, we understand that lip care needs can be highly individual, especially when dealing with very dry lips that may require more intensive hydration or different formulation approaches. Sometimes products that provide adequate moisture for some users may not be sufficient for those with more demanding hydration needs.

    We truly value your feedback as it helps us understand how our products perform for different lip care requirements. Please do reach out to our askINKEY Team if we can support you further with your experience 🖤
