Retinoid purge leaving indented scars. Any suggestions?

I started using 0.05% tretinoin nightly 5 weeks ago. The irritation and peeling are manageable but my acne has gotten worse. Before treatment I'd have one or two active pimples a month and now I have several new ones every few days. These new pimples are mostly leaving dark marks but some of them are leaving shallow indents too. I started this to help with aging and minimize breakouts, not to totally mess up my face. Will the indents go away? I'm really worried. My skin was smooth before.
