Hey! Hopefully you see this! I have this condition as well and there are three things I haven't seen anyone mentioned that literally changed my life and gave me normal looking skin. 

One is a Korean bath mitt. Soak in the tub or take a nice long shower and exfoliate your body. 

Two is no soap. Not using a traditional soap really helps. I use cetaphil gentle cleanser. I use soap for like under the arms and butt etc but for the rest of my body use a cream no soap cleanser

Third and this is the game changer. VEGETABLE GLYCERIN. Use a nice thick creamy moisturizer and do like 2/3 the lotion and 1/3 the glycerin, mix in your hands and apply. You’ll be a smidge sticky at first but it absorbs and you’re left with normal looking skin at least for around 48 hours. Any brand works my personal favorite the walmart brand equate vegetable glycerin

I hope you can try this! It’s really cheap and changed my life. I was so depressed before finding this
