Yes, i agree with Freddy - don't go messing with the area until you get a dermatologist to look at it. The solarium must be a sun tannning bed? If so, don't do that as it will darken the surrounding areas BUT also darken the areas around your mouth and you still have the 2 tones. I would cover it temporarily with a concealing makeup until the derm. gives you some insight. Cover FX is a great line for covering even birthmarks...also Dermablend from Vichy is similar, just not as many shades available. Maybe use a cream with AHA in it (Reversa, Neostrata) until you see the derm. hope this helps. PS if you do use Cover FX or Dermablend, or one like it, put it on in very light coats - ie several light coats rather than one heavy application. And gently wipe a sponge along it after application to blend in with the remainder of your face.
