Burn scar due to spillage of hot water 4 months back still left me with stubborn white & pink rough scars. Any treatment?(photo)

Hot water peeled my skin out.The burn got completely healed with collagen dressing after 3 weeks but left stubborn white scars behind, some pinkish marks & rough patches in some of the parts & even after 4 months it hasn't improved much.Though in some of the smooth surfaces,whiteness did get reduced upto few extent by application of Hexilak gel for 3 months,but it seems to have burnt in the deep layers in some area making them rough & highly discoloured &pigmentation hvn't progressed much there.
