Cycle Breakout

I have oily-acne/sensitive skin. Aside of that I really have a major skin concern at the young age. When I breakout, I used to apply skincare that are consists ingredients to treat acne like salicylic acid, benzoyl, tea tree, azelaic acid and glycolic acid. I am aware those ingredients might ruin my skin barrier so that I always keep balance my skin with hydration like hyaluronic acid, calming with centella and soothing with aloe and panthenol. As a result, my skin are really clear but only leave on the scar effect from the pimples. Next routine of my skincare, I used to apply most of skincare with a range of soothing and calming and strengths back my skin barrier like ceramides. In this case, I am really tried to avoid from using active ingredients like niacinamide, alpha arbutin, ascorbic acid or retinol in high percentage as I know my skin can't tolerate with them. Plus, I also always precautions with any ingredients that might harm or sensitive on my skin like fragrance, alcohol, sls/sles, mineral oil and paraben. Additionally, I also keep my cleanliness environment and practice healthy dietary. However, my skin always keep breakout even after I care of my skin precautionary. So, I have to go back to my anti-acne skincare routine and the cycle goes around. Now, I didn't have no idea what to do with my skin as it has happened a long time and repeatedly. Even my dark spot and scar doesn't had time to pale but the new acne already pop out again. Actually question that I would like to ask is did I really need to focus on my gentle anti-acne skincare routine even after my skin has heal from breakout?
