This Doctor is the worst dermatologist I have ever seen. I went in for a brown spot on my forehead, and he sprayed liquid nitrogen on the spot. I trusted him, with this procedure. Well, I did this procedure in April, and to this date I am seeing my dermatologist in Beverly Hills, to in-do his damage. He burnt my skin and the spot was 100 times worse. All red. I am from CA and moving back in 2 months. Thank God for my dermatologist in Beverly Hills, CA, after7 months this red spot is finally going away. I have flown in to Beverly Hills, every 2 weeks to see my doc there to fix his damage. Do not see this doctor for cosmetic procedures, because he has no clue. He wouldn't even give my money back of $180, as he said he doesn't guarantee his work. What a piece of work!!!! Bad news.
