I have tried a ton of acne cures that did nothing but irritate my skin further. Below is the only thing that has EVER worked for me which is surprising given how cheap and
simple it is:
First you will need a small (about 6oz) glass bottle with a pump top. It is important that it be glass so you can clean it well every time you make a new batch of toner, and the pump is more hygienic.
Start by squeezing about 1 tablespoon of the purest aloe vera gel you can find in your clean bottle. Do not use the one with lanacane or any other additives.
Next add about 20 drops of tea tree oil and 2 crushed aspirins. The aspirin is actually salicylic acid, which is an ingredient found in most expensive acne products. You can use any kind but I prefer the cheap, uncoated ones from the dollar store. They dissolve much better than the coated kind.
After that add about 1 teaspoon of apple cider vinegar. Do not use white or any other kind of vinegar as they are way too harsh for use on your face.
The last step is to add enough boiling water to fill the bottle. Let it cool slightly and screw the pump on securely. Store in your fridge and use nightly after washing your face. Apply with a clean cotton ball.
The aspirin has a certain solubility which means that only a certain amount will dissolve in water. You will have a few aspirin pieces floating around but that is normal. If it really bothers you, you can strain the toner through cheese cloth.
It does not smell too good, but it has made a huge difference in the way my face looks. I no longer have any cyst like pimples and my face is a lot less oily. I make a fresh batch every week.
I have also found that if I only wash my face at night and follow with this toner instead of night and morning, my face is a lot calmer and less oily. I use St. Ives medicated apricot scrub but I am careful not to scrub too hard as that will only make matters worse.
Good luck! I hope it works as well for you as it has for me :-)
