Breakouts

So before this past year I had great skin gained almost 25 pounds and started to see breakouts which led to scaring behind my thighs and under my buttcheeks :( Some have said because of my weight gain. So I started to eat and drink water am down to 29 pounds gone but I still have the same problems. I've been exfoliating everyday and putting acne products and nothing. This has really made me feel ugly about my body. Even more so that summer is coming. Please help !! TIA
