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.
