Hello, I did a microneedling with PRP last month. I do not have big holes - just tiny indentations from when I had a bit of acne when I was younger. After my microneedling with PRP all of the holes went away I was shocked! But after about a week literally every single hole came back! Is it normal that they all came back? Should I keep doing just regular microneedling and they will eventually go away completely or am I wasting my time? thank you!
