i want to make a vit C serum with ascorbic acid but my problem is that i dont know how to bottle or package my product to preserve the activity ascorbic acid. this form of vitamin C doesnt like oxygen. so if i pakage my serum in a jar or bottle, within 5 days it would be useless. i was thinking about using a vaccum food sealer and bags and make individual packages. but problem is thats a lot of work and i dont have a vaccum sealer. anyone have any good alternatives or insite.

Why don't you make it each night before you put it on your face.......you won't want to use the vitamin c serum on your face for a long period of time anyway. I know that doesn't solve the bottling issue, but it seems easier to me. Let me know how it goes, I am interested.

yeah i was thinking of doing this until i decide to make my serum a bit complicated. so... i noticed that many vitamin C skin care products are sold in powder form. is this the most stable form of ascorbic acid?

 

[dtilford]

When you are dealing with vitamin C in skin care you need to use it in the form of L-asorbic acid. L-asorbic acid is an antioxidant, helps heal sun damaged skin, hydrates, and improves collegen. If you buy this or make it you need to make sure the ph level is low-because it is an acid- and you also need to make sure the concentration is high. I am not sure if the powder is better, to be honest I have NEVER heard of the powder form (in L-asorbic acid). I will check with someone and get back to you. You can also buy the supplements at GNC and take those everyday. Another good idea is to either buy the product or make it, then go to an esthetician that has an electrotherapy machine and have her put it on your skin and then use the machine. This will insure propper penetration.

a while ago i gave a few sites that sell cosmetic ingredients and on 3 sites they sell ascorbic acid in a power form. this is the form im using but on Ascorbic Acid by Skin Actives its recommended to mix the power in water for every application.

thanks dtilford for taking the time to help me out here.

Mising it with propylene glycol or butylene glycol will keep it stable for a little longer but might feel a bit sticky on the skin. I think it would be best to make a new batch twice a week I'm afraid.

ok, thanks.

With Germall plus in the serum, and keeping it cool and in the dark - how long will it be stable? If the PH stays good, does that mean it is stable? Can it stay good for 2 months tops?

I am confused...

If it's L-ascorbic acid in water then methinks ~3-4 weeks is the most you can get out of it.

For example Vichy makes a vit C serum you have to mix at home and they say it's good for 21 days and should be stored in fridge. It's the most realistic thing I've ever heard a manufacturer say about L-aa serum.

I so hoped for 8 weeks, Ray. Because I send 20 ml of to my family.

If the pH is still good after 8 weeks - what does that mean then?

 

[blueman]

If the color (clear) and pH is ok (under 3.5) after 8 weeks then it probably is. Difficult to say.

I agree!! I actually used to buy a Vit C serum I made at home from Sesderma I don't ever remember them saying how long the shelf life was after it was made and I know they NEVER mentioned the fridge. So good for Vichy for at least saying that much!

Is she not allowed to like it? Must she only like what you approve of?

 

[blueman]

Well, no, it's like this: you can have your own opinions about things, but not your own facts.

Yes of course that's logical but this member was not stating facts she simply posted a link to a form of vitamin c.
