OK, so this stuff is pretty awesome. Except it stings.
The awesome part: goes on very nicely, spreads evenly, absorbs quickly, leaves no residue, matte finish which is very hard to find in an SPF, zinc oxide based which may actually be good for acne.
The stings part: upon application I get a warming/stinging sensation which can last for up to two hours or so. I am relatively certain this is due to one of the sunscreen ingredients.
Bottom line: this is the best sunscreen I have tried to date aside from the stinging. I am going to discuss this issue with our manufacturer and see if we can improve upon it.
