Great saddle bag item
Style: Face Stick, Size: 0.45 Ounce (Pack of 1)
I love the size! This small sized product is handy for the outdoorsman. Very convenient to keep in pocket or saddle bag. Product kept my ears, face and back of neck from sun burning. Easy to apply and rub in and was actually not oily feeling like most others. And an added bonus it help to keep nats and mosquitoes away from face, ears and neck!

Love the stick! I’m not a baby.
Style: Face Stick, Size: 0.45 Ounce (Pack of 1)
I don’t have babies anymore just teens, but I keep one of these in the car for back of my hands. It doesn’t either freeze nor get hot melty and gloopy and separated like a cream. Withstands both extreme summer and below freezing winter temps. Also you easily swipe it on in 2 seconds, avoiding getting palms slimy to facilitate driving. However I drive less than I spend time on my screened in porch. I’m not in direct sun, only shade, but by now we know that it’s uva light even hitting you on cloudy rain through windows that is aging and causing cancer. So I’m getting TONS of uv light. Every time I go out there, I swipe it on the back of my hands, since spf wears off quickly there from dishes hand washing etc. Since I’ve been doing this, age spots have faded off my hands. Hands age very fast. It doesn’t clutter and look sloppy on porch, and again, doesn’t freeze or melt! And a whopping 19.2% zinc is CRAZY!! I could of course see this being perfect for babies faces since it wouldn’t run into the eyes and it’s gentle as heck on skin. It is like totally thick and white though, if that matters to you or your baby. I also keep the adult sun bum stick (not mineral) in my purse. Takes up no room. It is less white/more cosmetically elegant than baby mineral one, and I touch up my face with it. I reapply sunscreen every 2 hours (don’t wear makeup). These things are perfect!!!! They last forever too.

Small small size but nice to carry around in purse or beach bag.
Style: Face Stick, Size: 0.45 Ounce (Pack of 1)
This sunblock works really well. I like that it is only mineral based and it glides on easily . Due to its compact size I can carry this in my makeup bag. I placed sunblock every 2 hours on my face while I was in the swimming pool and I never got a sunburn. Pricey but easy to apply and compact size .

Great for the face
Style: Face Stick, Size: 0.45 Ounce (Pack of 1)
Works well, nice ingredients and easy on our babies skin. They do leave a white tint though that can take awhile to fully rub in

Small size, great product
Style: Face Stick, Size: 0.45 Ounce (Pack of 1)
Great product, just wish I had read the description better because this stick is TINY. On the flip side, its easy to carry around and doesn't gulf my baby's face.
