Pimple cream only works with the occaisional pimples.
If you are developing acne, then thats a skin infection that will need treatment if you want to get rid of it. You know how you always see those people with bad skin, and they always say "i always use pimple cream and wash my face, it just never goes away!", thats because you need proper medication. So, if it looks like you are developing acne, get in quick and see a dermotoligst. Once you get rid of the skin infection, it will most likely never come back, you will only get the occaisional pimple here and there like most other people.
So yeah, i'd say just wash your face, use some pimple cream, see what happens. If that doesn't help, see a dermotogist ASAP, since it is likely you are getting real acne.
