Acne problems

So my skin frequently breaks out and I realize it's part of life but it makes me really insecure and I hate looking in mirrors and seeing how bad it gets. Not only is it extremely red and irritated looking all the time but it also scars my skin so badly. I've tried so many things to make it go away but nothing so far has helped and it's so embarrassing when random people stop me and try to give me advice there was even a time a man at a restaurant asked me if it was a rash and told me to try cortisone to help fix it.my skin is sensitive to some face washes so it makes it difficult to find a product that will work, but I'd be sincerely thankful for any suggestions to help with scarring or getting rid of my acne.
