Decent but not the best
Size: 1.7 Ounce (Pack of 1)
I like that this sunscreen is matte and tinted, but that’s about it. I have pretty oily skin and the mattifying effect only lasts for about 6-7 hours.
Unfortunately this product doesn’t absorb very well either. It tends to accumulate in any wrinkles and also tends to sit on top of any sort of facial hair or areas of dry skin.
A much better product, that absorbs very well and controls oil literally all day long, is Trader Joe’s mattifying facial sunscreen in the sea foam green tube. It isn’t tinted like Sun Bum but it beats it in every other category, especially in price.

Holy grail face SPF - mineral, tinted and matte
Size: 1.7 Ounce (Pack of 1)
Title says it all. This is my holy grail face SPF. It’s mineral and non-toxic. It’s lightly tinted so it looks beautiful on your skin alone and helps even out your skin. It’s also matte so it wears well under makeup. It’s moisturizing and applies and blends smoothly onto the skin. Amazing product. I have it on subscribe and save.

Lightweight, non-greasy protection you can trust
Size: 1.7 Fl Oz (Pack of 1), Size: 1.7 Fl Oz (Pack of 1)
This Neutrogena Ultra Sheer sunscreen is one of the best I’ve tried, especially if you don’t like heavy or greasy sunscreens. It has a very lightweight texture that absorbs quickly into the skin and leaves a dry-touch finish, so it doesn’t feel sticky or oily at all.
What I really like is that it provides strong broad-spectrum SPF protection while still feeling comfortable for everyday use. It works great under makeup and doesn’t leave a white cast, which is a big plus.
I’ve used it on my face and body, and it hasn’t caused any breakouts or irritation. It’s also water-resistant, so it’s perfect for hot days or outdoor activities.
Overall, this is a reliable sunscreen that gives you high protection without that heavy sunscreen feeling. Definitely a must-have for daily skincare.

Good, Even for Sensitive Skin
Size: 1.7 Fl Oz (Pack of 1)
I have been using this sunscreen every day with good results. It goes on smoothly, absorbs rapidly with no grease or leftover film, and it feels moisturizing. I have sensitive skin in general, and this does not irritate my skin whatsoever.
It certainly exceeds my expectations.

A great sunscreen I have used for years!
Size: 1.7 Fl Oz (Pack of 1)
This is a product I have used with great success over the years and keep coming back to. Neutrogena is just a brand I really have trusted since my teenaged years of using their glycerin soap. This product does not disappoint. It dries down clear and moisturizes your face in preparation for makeup. I really appreciate that it plays well layering all my products and makeup like some sunscreens do. I also love the higher SPF of the product. I feel like the higher the better when it comes to the damaging sun. There is one thing I do not care for, and that is the smell. It has a strong smell at first when put on, but luckily quickly becomes unnoticeable, otherwise, I wouldn’t buy it. If I had to pick one sunscreen for my face forever, this would be it.
