I will be loved
Size: 3.4 Fl Oz (Pack of 1), Style: SPF 50
I bought this for my granddaughter who rows crew in a rowing club. This keeps her on the water many hours weekly catching sun rays from the sun, and reflected from the water surface. I made the mistake of 'sunbathing' as a teenager before people knew about the dangers of too much sunlight on your skin. I learned about the effectiveness of this product from my skincare Dr. My granddauaghter knew all of the danger, as she is a teenager, but did not do enough, for the same reason, so I sent this to her. She loves me, so she uses it. She'll love me more later.

The best 50 spf sunscreen!
Size: 3.4 Fl Oz (Pack of 1), Style: SPF 50
This is the best 50 spf mineral sunscreen I have found! It really gives a barrier to prevent sunburn on the skin! I use this 50 spf sunscreen on myself my kids my husband! It stays on for a really long time! And on my horses with pink noses! The cream is light, a little watery in the palm. It feels light and is not sticky on the skin. The smell is lightly tropical, which are my favorite smells! It does leave a faint white color on the skin when you put it on. It does it’s job really good stopping a sunburn!
