stable oil-soluble Vitamin C ester which has anti-oxidant activity, inhibiting lipid peroxidation. Topical use can mitigate the damaging effects of UV exposure.

Does not  irritate skin, but always patch test first

Usage: Typical 0.5-20% Some USA web sites advise it is safe to use at up to 30%.

Other jurisdictions place lower limits for commercial sale 

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.
