How should I care for my skin after a blemish treatment to prevent scarring?

A while ago, I finally mustered the courage to get laser treatment for blemishes to get rid of the tiny specks on my face. The clinic told me to apply a regenerating cream diligently, but

Is there anything special I should be careful about after the blemish treatment? A scab has formed, and I'm worried that forcibly removing it might leave a scar, so I'm being cautious. I'm also confused about when I should start applying sunscreen.

My skin is very sensitive after the blemish treatment, so I'm afraid to use just any skincare product. I spent a lot of money on this to get clear and radiant skin, but I'm extremely worried that if I don't manage it properly, the spots might actually get darker. I really want to know your sure-fire aftercare tips. I can't wait for the scabs to fall off so I can see my fair skin! Please help me out!
