Hello I Tried Using Tea Tree Oil And Apple Cider

hello i tried using tea tree oil and apple cider vinegar/water mix a few weeks back to help my chin area breakout. it appeared to be getting whiteheads and i think i may have burned my skin or something as there is slight discoloration only in that area...it did not affect the rest of my face at all. i cleansed using coconut oil for a week and used it as moisturizer as well and it seemed to get better. i bought MSM cleanser all natural and MSM serum to use but it is still stinging a bit only in the chin area when i cleanse and apply the serum. i also still have some discoloration as if under the skin almost redish only in that area of my face. is this because of bacteria in my chin area? the rest of my face and skin is great but only that one area. also i can still see little white head looking bumps in that area when i press my skin up against my face in that area
