Love!
Size: 1.7 Fl Oz (Pack of 1)
It’s a little runny but honestly doesn’t bother me at all. Gives me a good glow with a little coverage! Better than any expensive ones I’ve used & layers well with or without makeup. Just wish it was a higher spf but definitely buying again.

So moisturizing
Color: Rose
I love this lip gloss. It is so moisturizing and such a pretty gloss. I don't find it to be very plumping, but it is very hydrating. I love that it's giving me SPF at the same time. I keep one in my purse, one in my car, and one in my swim bag.
