Nothing higher than 36, but you don't need it. I am a MAJOR afficionado of the Spray Gel, but I don't use that on my face, as it has LOTS of alcohol in it. But...the regular gel, and the kids gel is fine on my face. (the kids gel smells like watermelon)
I am about as pale and pasty as they come, and I have not been burned since I discovered this stuff. DS wears it every day at camp, and since it's a spray, the counselors are not at all hesitant to help him reapply.
I prefer the spray to the gel, but that is just personal preference, either one works GREAT.
