Just ok - too thick to apply evenly
Style: SPF 50, Size: 8 Fl Oz (Pack of 1)
Just ok - very thick, so difficult to apply evenly. I use this for outdoor cycling and it works, but it's so thick that it tends to clump instead of smoothly covering the skin.

Doesn't go on greasy. Doesn't stink. Don't get sunburnt wearing it.

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.

This is the suntan lotion I’ll buy from now on.
Really nice suntan lotion. I brought it to a quick Florida trip in early summer. Very light compared to other products we have on hand. Not greasy. I plan to buy this in future once we run out. I also really liked the set of three 3oz containers which made it perfect for travel. I give this product 5 stars without hesitation.

Nice sunscreen.
Great sunscreen. Works into skin without residue. I get good sun protection and lasts most of the day.
