Why do doctors reccomend lasers to people whose skin was damaged, if lasers themselves can create identical damage?

I had a recent skin reaction to a retinoid & through my research, I have found many with similar reactions..whether it be laser, chemical peels, corticosteroids, retinoids, or even OTC retinol creams. And they all are just reccomended another thing from the list of "damagers" even tho their skin issues are interchangeable with those damaged by other sources..& most, if not all of these people are just then further damaged because of this. Why are harmful treatments being pushed like drugs?
