Face feels tight after washing w/ facial scrub.cheeks also feel "tingly".. like there are tiny bugs walking on my cheeks.what could be the cause?

Probably dryness: The facial scrub probably removed oil from your skin, which protects the skin from becoming dehydrated. Scrubs that contain alcohol can be particularly problematic. It may also be that your skin is sensitive to something in the scrub. You may wish to try a different scrub, or you can consider applying a thin layer of a moisturiser, baby oil or petroleum jelly after using the scrub.
