One day I read that Apple Cidar Vinegar, which apparently is the wonder cure for pretty much anything, worked on rashes.
Being mentally challenged with the belief that “if a little is good, a lot will be awesome!”, I went full strength ACV on the now scratched raw rash on both forearms.
Boy howdy, what an eye watering experience that turned out to be, but the itch was gone and the rash soon after that.
However, the itch came back with a vengeance when that dead layer of skin began to slough off.
Next I learned how a quality hair brush is very effective for both scratching and for removing the dead skin.
As a side benefit, the keratosis spots just came off like an old scab and now my old, sun damaged skin actually looks better, smoother and less wrinkled, too.
ACV seems to work, but I definitely won’t be using full strength again! Half power is probably more my speed.
