Somebody was asking where to get VC for whitening purpose. I heard some girls just
smesh the VC pill (that we eat) and mix it with other stuff like toner to do mask .
But I never dare to do so, as it's going to convert to an acid, we need to be very careful
with the ph value.

A commerically available cosmetic use VC powder is from Philosophy. Here is the picture,
you can mix it with the face lotion or cream each time you use. Again, I didn't use this
before, can't say good or not.
