There are many ways to rid of acne, which you could also research online for multiple solutions.
You can go to your doctor and ask to prescribe you any medicine for your acne. In my situation, I use this solution and soap bar that has been helping me over the past years.
Not only that, but you should wash your face and drink water daily. Sweat causes your skin to break into more acne as well.
One recommendation would be not to touch your face especially when your fingers aren't clean. Popping pimples that shouldn't be popped, makes your acne become worse as more acne comes up. It also depends on what you eat, which if you eat healthy, these pimples may disappear.
