Mediocre

I enjoy most Kosas products but was disappointed with this one. I purchased it less than a year ago and it expired so quickly (turned into thin liquid, like water consistency within a few short months). It had always been stored in a cool dry place. I personally do not like the « vanilla » scent in the product. I do not find it worth the price at all and I would not buy it again.

Meh. I feel like this coats your lips but then somehow doesn’t moisture it still and it left my lips more chapped and flaky.

The scent is trash- the formula is great

I’m nearing the end of my tube. I have many many lip balms- I always have something with me, so when I finish one I take note. The scent of this is genuinely disappointing- every time I apply I remind myself that my lips are going to feel great… and they do!

Not worth the price. It does not really hydrate or plump but it’s thin and it’s shiny. I will use it but won’t buy again.

I've been using this product for weeks now, it's not hydrating. I find myself reapplying this product so often throughout the day, and it doesn't do anything. I want to like this product because I like the brand but it's just disappointing. The texture and applicator is fine but the smell is not great.

Tastes awful

I shouldn’t have listened to the associate that recommended it. It tastes SO BAD, and does absolutely nothing

got from a beauty box. tastes and smells like rancid oil and plastic. leaves a goopy white film on the lips. 2 stars for at least being hydrating and clean, disappointing bc i like this brand

A pleasant surprise

I love this! It moisturizes really well, I love the feel on my lips, it lasts a decent amount of time, and has a nice shine. I got it in a Sephora kit and it was such a pleasant surprise. It’s one of my fave lip products now.
