How to help your skin if it has greasy porous? Try this white mask. You need to take an unbeaten egg-white, apply to your face, let it get dry, then repeat the procedure, thus you'll do it four times so you'll get four layers of the egg-white on your face. The mask gets more effective if you add a teaspoon camphor alcohol or lemon juice. Leave for 15-20 minutes then wash with warm and cold water.
