Well, it depends on how bad your face is like for example me i am trying so hard to get rid of my acne scars because most of them is filled all over my cheeks which is so embarassing that i sometimes cover them up and yet some  would still show based on how bad i have botherd it or how dry and red they are so i had used peroxide 2% before and i figured i needed something a bit more stronger so my doctor reccomened peroxide 4% wash which is better and stronger which my face needs. But if your face isn't really that bad and your over reacting then something to strong for your face woldn't be a good idea. Procative isn't always a good idea because it can sometimes worsen your face and if you stop using it, pimples may come back which means you would always have to by it everytime you would be finished. In my opinion i would not use proactive because i know some people that have used it and it barely did anything.

No, you can't use this product and go under the sun because this type of product has acid in it which means if you use this product and go under the sun you can burn your face and scars which may prevent the scars to get darker. So what you use is a moisterizer that has SPF 15 to block your face from the sun all the time like for instance clean and clear that has SPF 15 you can always use that.
