You have many options
There are many options for you to decrease the oil on your skin and your acne during the summer time. There are several over the counter products that contain benzoyl peroxide. Benzoyl peroxide removes oil from your face and also is antibacterial and anticomedonal (opens up the pores). I would recommend choosing a facial wash that contains benzoyl peroxide 2.5 to 10%. Also, many people develop acne from sunscreens. To prevent one, pick one that is oil free and non-comedogenic.
