Would pico laser be able to completely get rid of PIH from chemical burns? (Photos)

Hi there,Thanks for your photos and enquiry.
The pigmented scars look fairly recent from a chemical burn.
I would give it about 2 months to allow complete healing and use a gentle scar cream with skin lightening ingredients and then see your Dr about Picosure for reduction of PIH. Yes the skin will get bettter and the pigmentation will fade in time after a few sessions (the speed varies among individuals), barring sun exposure and further chemical exposure. I hope this helps.
Best wishes.
