What should I do to the spot leave it alone to fade away, or do I need to use some type of cream.
It really depends how long it has been there but usually it will go away on its own. If not you can have a quick laser treatment to remove it.
If you have dark spots, then please use spf at least 45 every day , 365 days a year. The sun will be trying to make your dark spot darker, even if you are not going to the beach!!Hydroquinone might make it look worse, if you get a light circle around your dark spot. Depending on your skin tone I would try to leave it alone except for the sun avoidance. PS don't ever pick off the scab. It is there for a reason!!Be Well,Dr Johnson
