Always in my purse!
Size: 0.5 Ounce (Pack of 1), Style: SPF 50 Stick
I have been really happy with this sunscreen stick. I was hesitant to try it because I read several reviews saying it left a white cast and felt greasy, but that has not been my experience at all.
I have dry, acne prone skin, and this glides on easily without feeling heavy or oily. It actually gives my skin a healthy glow rather than looking greasy. Best of all, it has not caused any breakouts.
I also use it on my 6 year old daughter, and it works great for her sensitive skin as well. The stick format makes application quick and easy, especially when we are out and about.
The tube is on the smaller side, but the price is lower than many mineral sunscreen sticks, so I think it is a fair trade off. Overall, this has been a great sunscreen for both me and my daughter, and I will definitely repurchase.

Great
Size: 0.5 Ounce (Pack of 1), Style: SPF 50 Stick
Feels light and easy to apply. Small enough to carry in your purse. Not white on my skin but I am light skinned. I have vitiligo and it's great for my arms.
