I had my second dermapen session (2 & 2.5mm) yesterday. Last time (1.5mm) I broke out a little about a week afterwards, this time the following morning I woke to lots of little white heads all over my face, it is worse than the photos now. Is this normal? How should I treat it? My doctor said to carry on with my normal skincare routine and it's a normal reaction, but I can't find this in anyone else's stories so wanted to make sure I don't do anything that will make it worse!
