Wanting to remove filler(restylane) that i had put in forehead for an indent about 1 year ago. I was trying to wait it out but I don't even see a slight reduction in the fullness and its been just about 1 year. Is this safe? What are the side effects as in should I be expecting tons of swelling? Will I need to take off work the next day? Do you think it will dent my skin worse than it was before?
