I have tested two lasers to try treat BN. Mentioned in picture, the nd one month and a half ago and the second 1m. Why is the surrounding lines seems more dark? I have started with nag nd and after one month the doctor did not recommend to continue and said "live with it" because it become spotty. But I insisted we try something different. Can I treat the whole area with Nd and if there are areas not treated well can I only go over it again to reduce until it's even or at least not noticeable
