Are CO2 laser and microneedling with PRP good for topical steroid damaged skin? (photos)

I am 21 years old. My skin is damaged because of extended use of topical steroids for eczema and rosacea. After stopping the cream I now have steroid induced acne, fine lines, large pores and thinned skin. My doctor has prescribed doxycycline and antihistamines to calm the acne down. He then wants to move forward with laser resurfacing or microneedling. Is this a good idea? Will it further thin my skin or will my skin be able to regenerate itself since I am young? Thank you doctors.
