Also with the lemon as a scar treatment put some lemon juice in some sugar (No splenda, or any artificial sweetener) and you can use it as an exfoliating scrub on your body and face which will help lighten stretch marks (obviously no instant results), hyper pigmentation, and gets rid of the little bumps on your arms :D
Also if you want to clear out your pores you just have to boil some water, put a towel on top of your had and let your face hover over the pot. The towel is for keeping the stream from escaping.
This is cool!!
