I'm curious about how to manage acne before it forms.

I really hate the red marks left behind after the acne goes away.

So whenever a new breakout appears, my first thought is that it might leave a scar. I know the most important thing is not to touch it, but if inflammation has already developed, I don't know how to minimize the scarring.

Is it better to see a dermatologist from the early stages of acne? Please let me know if there are any methods that helped prevent scarring.
