    LOVE IT

    I honestly was very skeptical of this product. I have used several "lip plumping" product which usually burn and smell bad. I have been using this product for about a month and I truly am amazed. I was a smoker for over 30 years and finally quit 2 years ago. I have some lines on my lips from smoking/puckering. My lipstick will often settle in those lines/wrinkles and I hate that. The reason I know this product works is one day I applied some dark colored lipstick and it did not settle in the lines because the lines smoothed out. I was amazed! I will continue to repurchase this product. The taste and smell are not bad but also not the greatest but SO worth it.

    Doesn't work, ingredients don't make sense

    The peptides stimulate collagen etc. For volume you need ingredients that act on fat cells (that increase their size, multiply them etc.). So the ingredients don't make sense for a plumping lip balm. I didn't notice any difference after 4 weeks.

    For a glossy lip balm I like it, unlike some others, this one stays quite long, once the most slippery layer is gone a more creamy sticky layer remains. It's okay for a basic glossy lip balm, but for that it's expensive. The scent was a bit stale, it was produced 2 years ago apparently and they sell them until 3 years after manufacture. I don't know if that's common, but I think it's a bit too long. I don't know if mine smelled the same as a fresh one, I can't compare.

    My fav lipbalm, NB

    Been using this balm for a couple of years now, and it's still my favorite and daily saver. The Berry tinted balm is my favorite coloured one, which is for me the most noticeable.
