4th grade!! That's a long run. Even, I had the same situation when I was in standard 10th. Then recently, I have started using Zeroblem serum and guess what!! It just simply worked for me. :) Yes, it will take time to get over acne and scars, but it made the redness ease and still kept the moisture of the skin, it made my skin smooth and blemish-free too. May be you should give it a try!!
