The aspirin - salt mask

Ingredients

A bottle of non-coated aspirin (any brand will do just fine) and a wee bit of moisturizer.

Instructions

Mash up 6-10 uncoated aspirin in a small dish or bowl. I find using the back of a spoon works best. Mix with the moisturizer until the consistency is that of a fine paste - it should not be runny. If it is, feel free to add another aspirin or two. Apply to face and/or neck. Let dry completely, then rinse off with warm water, rubbing in small circles to exfoliate.
If you're in a hurry, you can use it just as a wet exfoliator - don't bother waiting for it to dry, just massage it into your skin and rinse off.
If you don't have uncoated aspirin on hand, try using Epsom salt, which draws out impurities. As a bonus, you can throw a handful into your bath water and soak in it to soothe tired muscles!
