FAQs

HOW DOES IT WORK? Unlike traditional lip plumpers, this balm boosts volume while protecting your skin barrier and locking in moisture - no irritation, no sting.

THE HERO INGREDIENTS?6% Tripeptide Complex: Boosts lip volume over time by targeting volume loss for plumper, more defined lips. 2% Ultra Filling Spheres: Dehydrated Hyaluronic Acid absorbs water and expands for instant plumping. Smooths fine lines and locks in moisture.

WHAT HAPPENS IF I STOP USING IT? You’ll start seeing visible plumping in as little as 2 weeks. Keep using at least 3x daily to maintain results.

CAN I USE IT MORE THAN 3X DAILY? Yes - 3x daily for best results, but reapply as often as you like.

WHERE DOES IT FIT IN MY ROUTINE? Use it as the final step AM + PM, or apply anytime during the day.

IS IT CLEAR OR COLOURED? Clear. Adds a natural sheen that works alone or on top of lipstick.

“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_

“I love that I can immediately see a difference in how defined my lip shape is and their overall fullness but they still look natural and like they’re my own!”- @‌skinwsara

Reviews Summary

Customers say this lip balm delivers mixed results for hydration and plumping effects. Many appreciate its moisturizing properties and subtle plumping when used consistently, especially overnight. Common feedback includes concerns about the texture, with some noting grainy particles. The formula receives varied responses - while numerous users report soft, hydrated lips, others find it drying. Regular users mention seeing gradual improvements with consistent application. The taste and smell emerge as frequent discussion points, with several noting an unpleasant flavor. The shine and finish earn praise, though some point out it doesn't last long on lips.

I really like the glosses, but...
I find the texture too runny; I would prefer it if they were a tad thicker. I have had it leak in my purse also
