This is in response to the original question.
Soap bars cured my acne. I'm not kidding. I still get a few breakouts... say, two pimples a month, down from about 10 a week. I'm 34, and had adult acne all the way until I started trying my salt bars on my face. I like to shave a salt bar down with a vegetable peeler, then mix in baking soda. Just a few weeks ago, I learned why it works so well... there is a certain acne-causing bacteria that loves a pH of around 4. That's pretty acidic. Salt bars take a bit more oil off, and mixing it with baking soda gives it more alkalinity, and is soothing.
I don't wear foundation anymore. I used to put it on before I left the house to get the mail.
I've given my salt bars to three friends with acne. Now I need to make sure I always have some on hand, because they keep coming back for more!
Also, they're very inexpensive to make. I use coconut oil at 20% SF with equal amounts of plain, cheap table salt.
They're also a lot quicker to make. You do need to watch it as it hardens, because it's really hard to cut if you wait too long. But I don't have a lot of time on hand, and I find that salt bars trace faster and harden faster. I shape them within 24 hours (clean the edges with a vegetable peeler) then let them cure and they are SUPER hard!
