This used to be one of my favorite collagen lip serums however the formula definitely changed. I used to use it nightly and put it on under the laneige lip mask and it really did make my lips more plump. However, now when I use it three days in a row my lips get a weird tingly sensation that doesn’t go away and I know it’s from this because once I stop it goes away after a day or two. It also does not hydrate your lips. As a result, I would definitely recommend trying other lip plumping or lip sleeping masks on the market as they are likely to be way more effective.

Super hydrating yet not glossy or sticky, plumps without stinging. The reason I did not give it 5 stars is because how difficult it is to apply because of the watery texture. The packaging is great.

I have gate-kept this product for so many years because it is my winter time secret weapon! Tbh even year round, this will transform your lips! I used to get severely chapped lips during the winter, no lip balm could spare my lips from the frigid -30 winds. Then I purchased this product. Now I originally purchased it to plump my lips, but I quickly discovered that it also prevented my lips from getting chapped. I put this on once in the morning, before I left the house, and I could go all day without applying lip balm. No cracks, no dryness, just perfectly smooth lips. I’ve repurchased it consistently for the last 6 years.
