Help with KP

I have KP aka the chicken skin which I'm sure most of you have heard of. I've been seeing my dermatologist and she recommended a hydrating cleanser and prescribed lac-hydrin. I've had this skin condition for the last 17 years of my life and it's only spreading and getting worse. I've used coconut scrubs and sugar scrubs to exfoliate and applied over the counter lotions from cetaphil, cervae, Dr. Derma to amlactin. I've also spent a lot of money to get microdermbrasion done, the results were softer skin but the bumps and discoloration are still there. It's almost summer and I've always been self conscious about the KP on my arms. I would love love love to just wear something cute and pretty that's short sleeve for the summer season. I've dealt with this for so long, I've cried several nights because I've tried so many things and spent so much money and nothing has helped. After this pregnancy I have to go back and see my dermatologist and get back on track to finding a new solution for my KP because it seems to have spread more and leaves a brown discoloration 😭☹😭

For those who also have KP what products have you used and found helpful? Thanks!!!!!
