Excellent product!!!
Size: 3 Ounce (Pack of 1)
I’ve been getting into more natural skincare lately, especially beef tallow products, so I wanted to try a sunscreen like this. I like that it uses tallow along with zinc oxide for protection.
The texture is smooth and not overly greasy, and it blends in better than I expected for a mineral sunscreen. It leaves my skin feeling moisturized. I’ve used it on both my face and body, and it feels comfortable throughout the day.
It’s also been good with my daughter’s skin, even though she has skin problems, which has been a big plus for us.
