I have two hypopigmented patches resulted from deep dermabrasion and wrinkled sagged skin because of steroid use. I have been microneedling and using chemical peels. I feel the difference, but its taking ages. Can I use ablative laser like co2 or erbium, would that help restore my skin? I fear it would cause more hypopigmentation or contracture like structure to my already hypopigmented patches. i really want recovery in a couple of months(if i can) :( really depressed.
