Why Redness Lingers
Popping a pimple or using spot treatments to shrink a zit can flatten a blemish, but redness can linger even after your pimple has disappeared. Depending on inflammation, you may even notice that redness remains on your skin for a week to three months. This discoloration is known as post-inflammatory erythema or post-inflammatory pigmentation. It occurs because your skin is trying to repair itself. While there isn’t a way to remove redness altogether, you can cover any blemishes with patches to help you avoid aggravating the spot further.
