VERY stubborn PIH— how to heal it?
Two years ago I used to have a really bad skin picking problem. I provided the first photo for the purpose of showing the extent of it. I rarely get acne anymore and I don’t pick, however I’ve obviously been left with leftover darkness. When I started using tretinoin consistently about a year ago, I saw lightening pretty quickly and my skin looks way better than it did then. But eventually the spots plateaued and have looked like the second photo for about six months. They became less distinct spots and began to blend into each other as blobs of darkness. I have even picked up hydroquinone and the PIH is not budging.
I understand the stubbornness is due to me picking at my skin.
I would really appreciate some advice.
