Love this tinted sunscreen
Color: 01
I am very pleased with this Tinted Sunscreen, Tinted Moisturizer with SPF. It applies very easy and smoothly. I have tried many different brands of this type that had tint and this is wonderful. It feels lightweight and does look cakey on my skin. The price point is good and I will be ordering more.

This is excellent
Size: 1.1 Fl Oz (Pack of 1)
My dermatologist recommended that I use a tinted sunscreen for the summer when I’m outside. She even gave me a couple of sample packs. Those samples were very nice so I ordered some. I will say I was expecting a kind of Zinky smell and feel on my skin. But no, it’s got a very neutral nonexistent smell. And it applies beautifully. And looks nice all day. and the nice thing about it is if I have to go somewhere and all I need to do is just touch up my makeup with a little foundation it works, and I still have the sunscreen effect. Love this product. The price is great. And if you can keep my skin on my face from getting more basal cell carcinomas - well, I’m all for it because I don’t like having my face all scarred up when those carcinoma get removed. If your dermatologist recommends a tinted sunscreen. You won’t go wrong with this product.

The Absolute BEST!
Size: 1.1 Fl Oz (Pack of 1)
Neutrogena Purescreen+ Mineral UV Tint Face Sunscreen is the absolute BEST! The price is right! It stood up to the hot Florida beach sun! The product is not harsh on the skin. It does NOT sting my eyes. It is not oily. It doesn't dry out my skin. There is no offensive odor. It is lightweight. It blends in easily. The tint is subtle. It doesn't cause acne! It is just the BEST! MY only "grievances" are that I wish the bottle was 2 oz, and that the bottle had a more controlled spout so that the release of the product wasn't sloppy / messy, AND I wish the bottle had a flip snap top for those with hand disabilities. Those perks would make for THE MOST PERFECT suncreen BUT those grievances are NOT a deal breaker. I just love this product!

It’s just OK
Size: 1.1 Fl Oz (Pack of 1), Size: 1.1 Fl Oz (Pack of 1)
It’s a perfect match to my skin tone although the coverage is so light that I’m sure it doesn’t matter too much. It takes a minute to blend in like most other sunscreens. It’s not my favorite but it’s not the worst. I have oily acne prone skin and after using AI to research ingredients in SPF I went with this one bc it was less likely to break me out compared to others. It is pretty greasy and makes my face look more oily than dewy so I just use Paula’s choice shine stopper on my t zone and that handles that issue so that I don’t have to just throw this out. $20 for 1 oz is pretty steep I’d rather just get the Australian gold that has a more matte finish and is easier to blend

Good finish; but slow dry down, runny, stains clothes.
Size: 1.1 Fl Oz (Pack of 1)
I use this in the lightest shade. It's runny, and it takes about 15 minutes to dry down. It also transfers and sometimes stains my clothes if I'm not careful. The stains do come out, but meanwhile I'm walking around with a dirty shirt. So WHY have I purchased it repeatedly? Once it does dry down, the finish is beautiful. It's radiant, but not overly glowy. On my normal (not oily or dry) skin, I don't need a moisturizer with it. Most importantly, the color is the perfect shade for me. I get compliments on how good I look every time I wear it. I wish I could find a skin tint or balm in this color, so I could use it over a clear sunscreen. Until I find one, I'll have to keep fighting the Purescreen Tinted. Anyone have any suggestions?
