How do I get rid of my body acne quickly?

Hi! I have acne on my body, being more precisely, on my shoulders, chest and a little on my legs.

Summer is coming up, and I really want to start wearing shirts and shorts that only cover half my thighs, and, show my collarbones plus a little under (so basically right above my actual chest area). Also I need to start wearing dresses.

I just got body acne maybe this year, and I have idea why.

I want to get rid of it quickly, maybe at least a month or two months, until I need it almost clear in my acne areas.

Please do not tell me to buy things like pro-active where I need to order it and things, and I can't go to a dermatologist, please don't ask why. Are there any methods I can use to quickly get rid of my body acne?

I already know exercising and drinking lots of water help, also eating healthier.

Can you give me some really affective and good tips to get rid of body acne? Also, some home remedies I can make, and when I say that, I mean simple home ingredients that I probably have that can be used as home remedies to treat my body acne.

My acne is not very severe, but I really don't feel comfortable with it. And I feel like its growing a little.

Thank you!
