How do you make your Vitamin C serum tell me the recipe?. whenever I search for L-ascorbic powder there comes powders claiming to be pure but of different prices some are cheep and some are expensive I don't know the difference can you guide me to the correct one so that when ever I'll buy I'll be able to understand the difference between right and wrong...

Another thing is that I found a Vitamin C serum recipe on one of the forums... I'm just pasting it here...

1/2 tsp distilled water
1/3 tsp l'ascorbic acid
1/4 tsp propylene glycol
1/4 tsp hyaluronic acid

Read this please... and according to this recipe... do I just have to mix these ingrediants and apply on skin or does it involve any heating process?. and for how long I can preserve the solution?

Thanks a lot.
