Good for face application, small, takes effort to rub in
Style: SPF 50 Stick, Size: 0.49 Ounce (Pack of 1)
Bought this because I thought it might make face application easier with my toddler. He definitely prefers it, mostly because he thinks it’s fun to apply and he can do it himself. But it also takes a little more effort to rub in than just the thin normal liquid copper tone baby mineral sunscreen. Gives pretty good protection though, once it’s all rubbed in! It rolls up like a deodorant stick, so you can keep it low. It’s very small, like the palm of your hand, so it’s best just to use for face. If you use it on the whole body, you’ll run out fast. It’s nice to slip into the diaper bag without it adding too much weight or worrying that it’ll open and get everywhere!

Not just for kids!
Style: SPF 50 Stick, Size: 0.49 Ounce (Pack of 1)
As an adult I still do not like to use chemical sunscreens on my skin, but prefer the mineral type (zinc oxide). This one is easy to apply, goes on smoothly, and with its essential oils it even acts as a conditioner. I use it on my face and neck mostly, choosing to keep my arms, etc, covered. Used it for several seasons with good results.

love! must buy!
Style: SPF 50 Stick, Size: 0.49 Ounce (Pack of 1)
Pro:
Goes on white but fades and fades quicker when blended in.
Gives meca slight bright effect on face overall.
Hasn't broken me out - as far as i seen and known.
No weird smell( mine did not smell at all).
Not sticky, easy to blend on face.
I feel it is worth the price especially because i feel like the ingredients are not overwhelming or harmful.
Definitely a must buy!
Con:
Size, it is really small. I mean i knew it was going to be small in size but didn't imagine it be this small.
(But i personally like the small size for use and storing in my bag or counter.)
Definitely a must buy! Its cute, small, and useful.
