Compounding notes. this is a very easy to use, very stable, highly bioavailable oil-soluble Vitamin hit. Easier to use, and more bioavailable than the oil soluble powder (vitamin C ester) - which will often leave a little residue that needs to be filtered out.
it is easily absorbed by the skin, and studies have indicated that the absorption rate is 16.5 times that of water-soluble vitamin C.
if you find it a little cloudy then warming it up will usually clarify it.
(One of the beauties of this is it will not (usually) cause colour change to yellow/brown over time.
Not tested on animals. Not for internal use.
