KP treatments

Hi! I’ve had KP on my upper arms for years and I pick at it like a mf because it’s so satisfying. I’ve heard it goes away by 30, but I’m 20 and I have finally had enough picking my arms.

Can anybody recommend me a treatment or share some advice?

I hear AmLactin and CeraVe creams work great but I also wonder if treating them with a cream could affect my bodies natural maturation out this condition?

Thanks!!
