What treatments are effective for PIH after a second-degree chemical burn? (Photos)

I suffered a second degree partial thickness chemical burn five months ago, which became infected--twice. The blisters are gone, the skin is mostly smooth, but the redness remains. I have tried Elidel, moderate-strength topical steroids, and now lasers are being recommended. Are there other options for treatment other than lasers? Would microneedling be effective?
