Suggest Treatment For Indented Scar On Face

Hello, On April 12th I had a pimple and I put toothpaste on it because I thought that would make it go away. But, the toothpaste burned away the skin of the pimple, creating sort of a cut. It scabbed, and when the scab came off it left an indent. Worried about that, I scraped of the skin again hoping to create a new wound that wouldn t indent. Well, that scabbed again, and came off again, and was indented again. So now I have an indented scar I guess. It s been a month and a half about since the last scab came off, but it is still indented and the skin around it is still red. Will it fill in? I have never had acne or problems, it was just one pimple and one cut. I tried Mederma but that burned the skin, aloe didn t do anything. Now I m just using Vaseline. Will the indent fill in and will the redness go away? Will I look like this forever? Very concerned.
