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.

Best dry-touch broad spectrum sunscreen available.
I've use this for the past 10 years. It is highly effective. In addition, a small amount goes a long way and it is NOT GREASY!! That is a major plus for me. I keep a short beard and it is easy to use with the beard. It functions very well and I have not found a better product. Other than its effectiveness, you can't tell you used it.

Great sunscreen🌞
Neutrogena sunscreen is my favorite. It has never made me break out and use it on my face every day for years and never broke out from this brand. My doctor wanted me to use sunscreen 24/7 for years.
