i just tried this and it seems to have worked ok. i got an empty spring water bottle, put a bunch of asprin in it, put maybe 3oz water, shook it all for a minute or two. it stays together well and a little bit of the watery paste goes a long way. it looks like the asprin part seperates from the water if you let it sit long, i'm just keeping it cold and shaking it before use.
I tried it for the first time last week...didn't notice much difference except that my skin was really soft. I think I'll keep trying. But I have EXTREMELY sensitive skin so I was nervous on the first try, I figure if I didn't have any negative effects that's pretty safe!
I have been using the aspirin mask every other day for the past week and a half. My skin has really improved - and I have tried every sort of remedy for the past 8 years. It really helps with inflammation - which makes sense as aspirin is anti-inflammitory. Additionaly the aspirin has a molecule similar to salicylic acid - so it must exfoliate the skin the same way. (I checked with my dad - he has a chemistry background as well) I use about 6 aspirin in a small little cap (like for water or a medicine bottle) and add some water and apple cider vinegar. I let it dissolve mix it into a paste, spread it on and wait about 5-10 minutes.
There has been concern that the aspirin will be absorbed into the body through the skin - even so, not all 6 aspirin will be absorbed. Most likely only 1-2 aspiring doses worth would be absorbed at the max, and it shouldn't be a problem to take 1-2 aspirin every other day! This makes sense to me, and I would much rather take the health risk of 1-2 aspirin rather than the health risk of accutane.
So far my skin has been getting smoother, less red, and I have never had as few pre-menstrual acne. This is the first time I have gotten through PMS without a huge breakout.
