From your description, the red mark on your face may be permanent. The doctors are correct, laser surgery can be effective at removing scars or marks. I don't think you should have laser surgery done at such a young age. Wait until you're a little older, and then you can decide if you want to do the laser procedure or not. As for the red mark, try using a concealer with a green base to cover it up. A green-base concealer will not turn your skin green, it helps neutralize red marks and red inflammatory, and brings out your skin's natural color.
