Excellent product
Size: 0.5 Ounce (Pack of 1), Style: SPF 50 Stick
I carried this sunscreen around in my bag all day at an amusement park on a very hot day and it was very useful. It didn’t melt or soften up in my bag and was easy to use, kind of like deodorant where you turn the little wheel on the bottom to make it come up. I had applied a different sunscreen on before entering the park (also spf 50) and used this for touch ups throughout the day and it was enough for two adults and a child and we still had plenty left for another day. It applies very white and in visible streaks, so we just rubbed it in and had no issue. I always get a weird farmers tan after being in the sun the way I was and barely had any visible tanning this time. This is going to be a new essential for me for amusement parks.

Very noticeable white cast that almost looks like too light makeup
Size: 0.5 Ounce (Pack of 1), Style: SPF 50 Stick
I like that this sunscreen stick is compact, easy to toss in a bag, and doesn’t irritate my sensitive skin. It glides on smoothly and feels less greasy than some mineral sunscreens I’ve tried. The SPF 50 protection also makes it convenient for quick touch-ups throughout the day, especially on the face and ears.
The biggest downside for me is the noticeable white cast. While it’s easy to apply and feels gentle on sensitive skin, the white cast is very noticeable and hard to blend out. It left my face looking pale and chalky for hours, which made me self-conscious wearing it in public. I understand mineral sunscreens can leave some residue, but this one was much more visible than expected. It may work better for very fair skin tones or outdoor activities where appearance matters less, but I wouldn’t repurchase it for everyday use.

This is all I use and I hate putting stuff on my skin.
Size: 0.5 Ounce (Pack of 1), Style: SPF 50 Stick
Perfect, I have one in pocket for reapplying as needed especially when my hands are disgusting. Just like the directions say it is also excellent for lips, nose and ears. You can massage it in if you mind the white cast. I like the white cast because that is what is protecting my skin from further damage. I found that when used as directed combined with the CETAPHIL Sheer Mineral Sunscreen Lotion it also protects my sensitive and extremely sun damaged skin from wind burn. Since I put it on thick it prevents the biting insects from getting to my skin. I only use on my face because I cover everything else with protective clothing. Rather have a white cast than permanent sun damage. It doesn't burn my skin like many other brands I've tried.

Easy application, moisturizing
Size: 0.5 Ounce (Pack of 1), Style: SPF 50 Stick
I love this product. It's so quick and easy to use! My face tends to get dry throughout the day but this is amazing for it! It only leaves a white cast if i put a lot on (usually if i go out for a run/hike). Other than that, i rub it in really well and my face feels moisturized and looks glowy. I highly recommend. It is very small but i only use it on my face so it has lasted me a while.

Essential daily protection to complete my routine
As part of my skincare routine focused on improving dark spots on my face, sunscreen is a must. The Neutrogena Ultra Sheer Dry-Touch SPF 70 has a smooth texture, a light and fresh scent, and feels comfortable on the skin. It absorbs quickly and doesn’t leave a heavy or greasy finish, which makes it easy to use every day.
I like how it protects my skin without altering my natural skin tone, making it a perfect final step in my routine. It complements my skincare well and helps me stay consistent with daily protection. The pack also includes three tubes, which is very convenient and practical.
