I developed PIH after filler injection for under eye bags. The injection made them worse, so I had them dissolved with hyaluronidase. Almost 2 years later it shows no sign of improvement. Everywhere says PIH recovery is up to 1 year, so I'm very disheartened now! Will it improve with time? I can't understand why it's taking so long... Could laser make it worse? I'm skin type II-III.
