I was looking for a lip product that wasn't a tint, was comfortable to wear, and didn't dry out my lips. I usually have to apply Vaseline regularly or my lips will peel, but this one doesn't dry out my lips at all after application. I have sensitive lips, but the plumping effect is mild, so it wasn't a problem. It's a great product that can be used comfortably, just like skincare.
I used it on my chapped lips without any problems! In fact, it actually improved my chapped lips! Lol I use it daily. A small amount is enough for a natural look, and if you layer it up, the color really comes out. I'm glad I bought it!
The moisture lasts! I don't like sticky things, but this isn't too sticky, doesn't come off easily, and seems to have good color retention considering it's not a tint. If I had to point out a minor issue, it would be that when you apply it and the gloss part comes out, the contents tend to drip... Other than that, I love it.
I was surprised that this lip serum was even better than I expected. I reapply it every time I go to the bathroom at work. It leaves a refreshing feeling after application, and my lips feel moisturized. I recommend it so much that I want to give it to my friends as a gift.
I bought it because I was attracted to the idea that it would also provide lip care and give my lips a glossy, healthy glow. It certainly doesn't dry out my lips, and it's a healthy red color. However, it's difficult to apply with a lipstick, and my fingers get dirty when I spread it with my fingers. Given the texture, it doesn't last that long, so I feel like it's a little different from what I had hoped for.
