Hi my name is jatin I am 19. I am having grade 3 acne scarce on my cheeks. I want to get rid of them. I was suggested derma roller treatment. 1. I am having very small acne or some kind of pimples on my forehead. They are dry.seems like they are inside the skin. 2. I am having a scare on my right eyebrow (actually not on but it continues to where my eyebrow ends) 3. I am having very open pores on my nose. So my question is my dermatologist told me that he won t use dermaroller on my nose, eyebrow scare and forehead. Instead he told me 2 other thearepy for my nose and forehead. I got my first sitting day before yesterday. He just used it on my cheeks. But when I did a Lil research over internet. 1. Dermaroller can be used all over the face. 2. I looked some professional videos also. So now please tell me what should I do is he a good dermatologist and is he doing good just using dermaroller only on my cheeks. And I looked in a video that professional dermatologist in permaroller are provided some special dermaroller of grey colour. Is it true and in India also are they provided some dermarollare. I have few more questions please help.
