I believe equal to name brand rhyming with NitroGina
I believe it is equal to the name brand mentioned on the front side of the tube. It is 55 SPF Sun Protection Factor so it offers strong UV A and UV B protection which are the 2 ranges of sun rays that do the skin damage and burning. It is an easily absorbed lotion that when rubbed goes into the skin and is not visible. It feels good after being rubbed in in that it feels dry and not overly greasy or with no shine and sheen. If you put on a shirt over your skin with lotion it will appear on the inside of a dark shirt but it will wash out right away when that shirt is washed. It is a good product and offers burn protection to me in some clear-sky strong sun uses. Reapply after entering the pool or after an hour (all sunscreen labels say reapply after 80 minutes which I believe is per recommendations of the federal FDA or some medical studies). I reapply often and I still get tanned but I do not want to burn.

Super impressed by this!
Love this sunscreen and will be reordering it. It’s sheer, light, invisible, gives me the protection I need for my middle aged skin and I can swear my complexion has gotten better since I started using it. I’m super impressed how it’s comparable to more expensive brands in quality without the high price tag. It’s made me start looking into other skin products I can purchase from the Amazon brand.

How is this SO good?
I'm a sunscreen enthusiast. I wear sunscreen every day, and I know how hard it is to find one that is actually pleasant to use. It goes on like a white paste but it quickly blends in to the skin and becomes invisible. There is NO white cast after you rub it in. The initial white color makes it really easy to see where you have applied it. The lotion is very moisturizing but it's also fairly lightweight feeling, and isn't greasy. My skin is usually on the dry side. The smell is nice and neutral, some people might say that it has a bit of a "sunscreen" smell. But the smell is pretty faint and it doesn't linger. I find it to be pleasant, personally. Additionally, I have used this in the water and I find it to offer excellent water resistance even though it doesn't form a heavy-feeling layer on the skin. This is particularly impressive to me. This sunscreen will definitely be a go-to for beach days. It's great for face and body! The one caveat is that it tastes terrible if you get it in your mouth. So I definitely do not recommend eating it, lol. You might have this issue if you're particularly sweaty and the sweat drips down your face. In my experience many sunscreens do this, so I don't consider it to be a big deal. I'd recommend this for anyone looking for cost-effective and lightweight sun protection. It's great on face and body.

Good product
It’s very comparable to the Neutrogena version. Its light on my face, does not leave a white cast, and doesn’t break me out. The price point is excellent compared to the name brand one. I go walking almost everyday and live in a sunny and hot area where the climate is hot all year round. I haven’t gotten burnt since wearing this sunscreen. Definitely recommend *UPDATE* This sunscreen gave me acne. I rarely breakout and I now have five pimples on my face. I do not recommend!!!

Burns My Eyes
If your eyes have a sensitivity to sunscreen, they may have a sensitivity to this one. This product made my eyes burn for two days, with multiple washings. I have had problems with La Roche Posay sunscreen — if that is a helpful association. It has dimethicone —a silicone— in it (which might be the irritant). Its common in beauty products but some people avoid it for various reasons. If you have no sensitivities and don’t mind the silicone, then it could be an acceptable option for the value. It went on smooth and light, left no cast, and had a very mild scent. I will use it on my limbs, but I can’t use this on my face.
