Horrible stretch marks with PUPPS 😔

Anyone else have horrible horrible stretch marks? I have not gained a large amount of weight and I have used lotions/ oils twice a day since week 14 so please don’t tell me to use lotion. I was told it is genetic and my doctor told me there is nothing i can do. To make it worse I have PUPPS so they are itchy and red and worse now. I use cortisone since my doctor recommended it but i am miserable. i look awful and itch like crazy. Anyone have this experience? Did they ever look better after birth? Any tips for dealing with PUPPS?
