I have same on my thighs and hips,
I'm currently using Shea butter, they say it helps and after delivery, it will fade away too.
I'm hopping it's cleared off because it's not pleasant to the eyes
What normally cause it is when it itches u, u scratch it whenever ever you feel itching pls dont scratch just rub, hot balm on it whether rub or methalthom that's what I do and I don't have stretch marks
