Hi, My Face And Chest Has A Break Out Of

Hi, my face and chest has a break out of rashes for the last 3weeks , I had few unnoticable rashes before I used, the natural aloe Vera gel (got from the flower bed) I also tried bicarbonate of soda , I also used baby powder all this was for trying to get a smoother skin for my face but I ruined it even more,, I used fresh lemon yesterday thinking the rashes would dry but they didn't.. And for the chest am thinking its the perfume I use.. Doctor What should I do I really want my skin back to normal..
