Hello,
I am attmpting to DIY Vit C serum (thanks to all the fabulous posts on this forum!) and I had a question on Ascorbic Acid. Some of the skin care creams reference Ascorbic Acid in their ingredients lists, however, I have read on prior posts that pure L-Ascorbic is what needs to be used. Does anyone have any opinions on this? L-Ascorbic is hard to come by, even online, does anyone have an online store they buy L-Ascorbic from?
Thanks! |

Hi I use a serum called CRS serum and it contains l-absorbic acid. It can be bought in 10, 15 and 20% strength. You can buy it on skincarerx.com, skinwest.com, skinstore.com |

Hi nkristie,
Most products labelled "ascorbic acid" are, in fact, "l-ascorbic acid". The way to find out for sure is to contact the manufacturer and ask.
There was an in-depth discussion about ascorbic acid about a year ago on this board ... so those of us who took part learned a great deal about it!
Strictly speaking, "ascorbic acid" or "Vitamin C" is made up of "l-ascorbic acid" [the active part of Vitamin C] and "d-ascorbic acid" [the inactive part of Vitamin C].
As I understand it, when l-ascorbic acid degrades, it becomes d-ascorbic acid ... and the skin can only utilize the l-ascorbic acid [active] portion of Vitamin C.
A quick email or call to the manufacturer will probaby confirm that the "ascorbic acid" that you have found is, indeed, l-ascorbic acid.
Have fun making your DIY Vit. C serum. I love making my own ... it's far less expensive ... and I know it's fresh!

I purchased my ascorbic acid powder from BulkFoods.com.
Of course, they are not in on Saturday to answer this "burning question"
However, if any of you are chemists, they had this posted on their site:
Vitamin C Crystals (Powder) = Ascorbic Acid (C6H8O6)
Is this L-ascorbic or D-Ascorbic?
I don't know which receipe I will attempt, but I did open the powder this morning and mixed a small amount with tap water and used it as a scrub on my face. It tasted just like my glycolic acid peel! It seemed to be quite potent.
I just hope it is L and not D. When I investigated a bit online, many sources said that Ascorbic acid is a synonym for L-ascorbic acid. |

Hi belledivine67,
I can't imagine why a company would produce an ascorbic acid that was d-ascorbic ... so you're probably safe in assuming that it's the l-ascorbic acid form. I'd still check with the manufacturer next week.
As for mixing it with tap water ... as a "wash" I suppose it wouldn't hurt ... although I don't know how something that would have contact with your face for such a short time would do anything to help either!
The reason that most recipes call for distilled water is so that any metals and other contaminates within tap water are excluded ... as actives sometimes react negatively with such things.
Distilled water should be available at a very low cost in most grocery stores ...
Good luck!
