im pretty sure you wont be able to get rid of it by tomorrow you should just cover it up with makeup.

the same thing is happening to me right now, I don't wanna go out but I actually have to and it's really frustrating... but I'm managing to take care os this scar with aspirin and hipoglos (I don't know if you have it where you live, because I'm brazilian). smash an aspirin with 2 or 3 drops of water and put in the mark. keep it for a few minutes. when I was about to go out, I put the hipoglos to make the skin better for putting the makeup. It clearly doesn't cover the bump, but the color gets really better! good luck

it's hyperpigmentatiion .....when you pop a pimple it always leave this mark

Well its been 5 days and it is now pink because the brown stuff fell off. How long will it take for my normal skin color to come back? I have been going out and it's so noticeable. Make up isn't helping either... Thanks for your replies though!

Looks like hypopigmentation now instead of hyperpigmentation, though I'm not entirely sure. Give it a few more days and see where it goes.

If it is hypopigmentation, I do not know how long it will last. Hyperpigmentation could last from a few weeks to a couple years, hypopigmentation may have a similar time-frame.
