Please share your best tips for aftercare following dermatological laser treatments!

I recently visited a dermatologist and received a laser treatment, but now that I've actually had the procedure, I'm really worried about how to take care of it.

Which moisturizers or regenerating creams are best to use, and when should I start applying sunscreen thoroughly before going out to keep my skin looking neat and free of discoloration?

If you have any useful tips of your own that you always follow after laser treatment, or regenerative care products you recommend, please share them in the comments!
