Apple Cider Vinegar for a persistent spot & Lime Skin for liver spots on the hands:
Apple Cider Vinegar------My dermatologist's diagnosis of a persistent spot on the bottom left side of my face was" age spot"! One application of Apple Cider Vinegar got rid of it COMPLETELY!
Lime Skin-------As a right handed person, I have rubbed lime skin (rind) every single morning on my left hand after squeezing it in my herbal tea, and there are zero liver/age/brown spots, whereas, I do have some tiny light brown spots on my right hand!
These days, I use lime skin on both hands equally!
