Hello. I completed an at home Dermapen with 2mm needle for stretch marks 5/6 days ago. I have been left with these marks all over. What are they and how can I fix them? I have previously used yellow peeling oil (for unrelated treatment) which peels me very well, will this work? I also have bleaching creams with HQ but I’m worried using them would be too slow as this is ALL over me. Please help, thank you.
