Greetings. For freckles, u can go for chemical peels, as they give quite good results for freckles. even your pores reduce to some extent just with peels. Also micro dermabrasion will help u. Only if these are not helpful, u can do lasers which are very safe. The cost of the treatment depends on the type of laser the dermatologist is using and also on the area to be covered. Cost differs accordingly. If only your nose is being treated, then it may cost u around 2000- 3000 per session . Regards Dr Shishira
