Sudocrem-

It sounds crazy, but Sudocrem works perfectly as a primer under your makeup. It forms a layer over your face, so that your makeup stays on all day long. So if you are without a primer and you have sudocream at home. I've tried it myself once. Not all over my face in the t zone anymore.

Imagine if you have a spot on your face, this really works love it so well.

Sudo cream is a good tip to apply to your face before going to bed and leave it on overnight, this removes the pimples and imperfections, of course this will not work for everyone but definitely worth a try
