Great facial moisturizer
I use the cream every day as my daily facial moisturizer. It is amazing. I even use it before going to bed as a night cream. Definitely recommend this. I’ve seen a difference in the texture of my skin as well as how well my makeup goes on.

Best Baby Sunscreen ☀️
Size: 6 Ounce (Pack of 2), Style: SPF 50 Spray
Putting sunscreen on a one year old is never an easy task. So I learned very quickly that the spray was a must. I’ve tried several different kinds and have had issues with eye irritation because I’m sure as y’all all know (that I definitely did not know) the first thing they do when you put sunscreen on their face is rub it immediately in their eyes. Although this one is not completely irritation free, I have noticed much less irritation to her eyes (or maybe she’s finally learning not to rub her eyes after I put it on idk 🤷🏼‍♀️). Regardless this is a great safe, easy to apply sunscreen for babies!
