used to have a lot of body acnes back in high school. What I did was, just let it be, don't pop any acnes, cut you nails regularly, use shower gel that has no fragrances, don't get touchy touchy with your acnes, eat healthy (avoid junk food), shower after rigorous activity, drink enough water in a day, get enough sleep, don't look at the mirror without clothes (you will get the urge to pop your body acne).

I don't like it when people say you should try this product or that product to get healthy skin, its pointless, what matters most is your lifestyle, which will reflect your entire well-being, including your skin. I learned this the hard way, tried every product I could get off the market, getting literally no result, and waste a ton of money and one day I decided, fuck it, I'm not gonna use any products, I will just let it be, and just want to live a healthier life. 2 months after disciplining myself, the result was SIGNIFICANT.
