And I tell you, don't use laser to remove spots, use colored light. First of all, lasers are painful. You have to put anesthetic on your face and remove the moles one by one with a laser. It's okay. How can I remove freckles? Can you burn all the spots? Moreover, you can't wash your face for many days after laser treatment, and there will be small pits on your face, so you should be very careful in maintenance.
Do colored light, no pain and no side effects. You can check it yourself and describe a lot.
