This stuff is amazing. I use it throughout the day when I want a lasting glossy look and I use it every night as part of my beauty regimen. We all pay a lot of attention to our skin but ignore our lips when that skin needs just as much if not more attention than the rest of our skin.
Overall this feels nice going on. The applicator makes it easy to get a nice clean application. It warms to your body temperature almost immediately and lasts hours and hours although worn as a makeup or for beauty during the day you may need a touch up after eating, drinking, etc. Like all glosses although it does last much longer than the average.
The cost is ok considering you only need a tiny amount for each application. That means even with a few touch ups a day and daily use this will still last almost a year in my opinion.
I received a sample size from a purchase I made at sephora and I use it often and still haven't made a dent in the tiny bottle that I've had for a couple months.
I own the honey color which is essentially a clear gloss color when applied. I have tested the other two and they give a nice just bitten look to your lips without over powering your lips with color.
When I use it as a night treatment I wake up with extremely soft, plump and moisturized lips that are comfortable and feel and look very healthy. This also helps with the matte lipstick trend because when the lips are moisturized there's less deep dry lines for the lipstick to sink into. That being said, I wouldn't wear this as a primer or any time near the time you're going to wear the product as it is a completely different finish than a matte lipstick. It's just a great way to keep your lips looking and feeling healthy and prepping them for makeup and lipsticks.
The finish is a thicker glossy finish that feels lighter and protective. I love this stuff and will be purchasing when I run out of my sample as well as recommending to friends, family and you!
