You need this

It hydrates the lips from the first application; you feel a slight tingling sensation. It fills in fine lines on the lips, and the hydration lasts for hours. I used it at night as a serum, and the difference was immense. The next day, my lips were full and plump.

Eh’ not necessary

Ok but not necessary. Doesn’t seem to be a needed part of my routine. And does not plump my lips

Very good lip plumper

Very much love this. While it is not intensely hydrating, I do notice my lips are more plump through the whole day and it does absorb relatively quick to allow application of something more nourishing

I didn’t see any difference in my under eye bags. They felt tight but that’s about it; no visible difference.

Peter Thomas Roth, lip liner

After using the product for almost three weeks, I noticed that my lips were very dry and peeling. So I do not recommend this product. If I can give this product a 0, I'd be more than happy

not impressed

I had high hopes for this product. I do feel a little tingling after applying, but I have not seen any improvement in lip lines or fullness. The formula has a strange consistency and does not absorb well. It also makes my lips feel dry after the fact.
