Tips to get rid of spots overnight?Watch
On a serious note; Freederm spot cream works really well.
I think the only to get rid of a spot overnight would be by squeezing it.
Really cheap method too I personally would really NOT use toothpaste, especially if you have sensitive skin. Sleeping with it overnight will cause the toothpaste to dry and crack which makes it harder to come off in the morning and the last thing you want is to end up removing the spot altogether leaving behind a big acne scar. The purpose should be to try and reduce it and make it flatter so that its easier to cover with makeup but primarily you should aim not to actually REMOVE it and the strength of the toothpaste can do that. But I only go on personal experience where a little experiment with toothpaste on spots went wrong and now I've got quite a bit of acne scarring! I know for some people it works though.
Don't be too aggressive with the scrubbing and don't smear the spot cream all over your face... I did this and woke up with my face resembling bright red sandpaper.
Nothing has worked so far. I tried sudocrem after reading some reviews. It just got rid of the redness but the massive spot is still there on the chin.
