I am moving to Brazil due to my work, and I have done a research in order to continue my sessions for heal a hypertrophic scar ..I've found good clinics but none of them works with PRP...also, in my first session (in USA) I used a vita c + hyaluronic acid serum and my skin did not react well because in every application my scar turned more red and thick, so I stopped with the product and the result was good.. hope there are more options of products that can be applied after the sessions!
