Not worth it
Doesn’t really help with redness. Has an oat smell that isn’t very pleasant. Nice moisturizer that isn’t sticky. Not worth the price.

Calming
Light weight enough to wear under makeup. Feels nice on Rosecia. Decreases redness.

Must Have Beauty Product
This one of my favorite and must have beauty products. Works so quickly for chapped lips and just keeping my lips soft every day. The formula isn’t sticky at all and you can really feel how hydrating and nourishing it is

The best lip balm!
I’m so addicted to this lip balm!!! If you have secret chapped lips this will fix it in a day or two!!! And even if u don’t, it keeps your lips soooo soft!!! A bit pricey but it goes on sale a lot so watch for that.
