Can you make the Vitamin C Serum with just glycerine and no water? I know that it is water soluable, and I tried it and it never completely disolved. But I've seen so many vitamin C serums on the market that have no water in them and heard that it degrades it a lot faster if it has water in it.

I made mine with Aloe juice it dissolved. Can't really say I liked the texture though.

I thought Aloe juice or gel could have trace metals in it, which would degrade the Vit. C? Question

I know Murad has a patent on stabilizing vitamin C by making the serum waterless. The Murad vitamin C serum called Daily Renewal Complex. I have it.

How does Aloe Juice or gel have trace metals? Where did you hear this from?

If l-ascorbic acid dissolves in it ... it's probably got some water.

Aloe Vera gel/juice has a percentage of water in it ... by its chemical makeup.

Most things have a certain amount of water in them ...

Just because the element you mix with the l-ascorbic acid doesn't say "water" doesn't mean that it isn't made up of water. By the same token, just because the label doesn't say "water" doesn't mean that a certain percentage of water isn't in it, disguised as something else.

Even human beings are made up of a large percentage of water.

I don't know about aloe vera having trace elements of metal, although, that too would make sense. Most living organisms have metals in them as part of their chemical makeup ... rather like water. [Humans have all sorts of metals as part of our makeup ... zinc, magnesium etc.]

I do know that green tea is known to have tracel amount of metals and metals can degrade Vitamin C ... which is why it's important not to use Vitamin C within 12 hours of using a copper peptide.

If you want your Vitamin C to last longer, then you have to try for a formulation that has only enough water to dissolve the l-ascorbic acid ... and the rest gets made up of things like PG or glycerine ...

I made mine with enough distilled water to dissove the VitC,then I added HA(Sodium Hyaluronate/hyaluronic acid).It is still a little watery for me.But,it was my first batch.
It will be nice to get the perfect texture and its so cool to save money on the VitC,so I can buy other things.
take care,skincare addict Smile

So do all metals degrade Vit C?? I use Jurlique blemish cream that has titanium dioxide in it, and sometimes the vit c on top..

Vitamin C degrades hyaluronic acid.

Hmm. Good question about the sunscreen. Maybe we need to wait a certain amount of time before we apply anything else over the vitamin C serum?

Aloe Vera contains a lot of minerals, some of which are from the metalic family. It also has rare minerals in it such as rhodium and iridium. I have seen it used in many commercial vitamin C serums, but it's probably better without it. I see why it needs distilled water instead of spring water for that reason. Although I've never heard of minerals degrading vitamin C before and can't find any information on it online.

There is water in aloe vera and in most all foods. I don't think there is any water in pure glycerine though. Which explains why it wouldn't disolve. All the crystals just sat at the bottom. I added water to it today and it disolved. However I find that when I put it on it creates a thin layer that is very greasy and sticky. Even hours later my hand still sticks to my face because of the glycerine. My hair sticks to my skin now if it lands on my face. And the bottle of glycerine says that it can be used as a moisterizer, but I don't see how it makes a good one.

Maybe it would be better to use water only with it and just make a new batch every couple of days. I wonder how fast it would disolve in just water. I know there are many commercial vitamin c "masks" on the market that are not much more then vitamin C powder that you form into a paste with some serum and then rinse it off after 20 min.

I also don't feel anything with it. Maybe it's not a high enough concentration, but I thought that some people said it kind of stings and feels a bit acidic.

The reason I thought about the waterless vitamin C serum was because of this:

"One approach to improving vitamin C stability and reducing the potential for skin irritation is to use anhydrous vehicle, i.e. a topical base cream containing no water. Since water acts as a catalyst of vitamin C oxidation, anhydrous environment reduces the rate of vitamin C degradation. Anhydrous vitamin C is more stable not only during storage but also on the skin after the application. This is an important advantage, even compared to some stabilized water-based vitamin C formulas, which may store well but still oxidize quickly on the skin surface. Furthermore, anhydrous vitamin C tends to be less irritating than regular ascorbic acid products because the irritation is caused mainly by hydrogen ions generated by acid dissociating in water."

I've never heard of this before, but I did a google search and did find a few articles...

And I've always been using an HA serum with a Vit C serum........ and I had great results with a Henry Tianus vit c serum, in which the second or third ingredient is HA.

Interesting, would vit. C then degrade Hyaluronic acid in the skin, not just topically applied HA?? Then, isn't it counter-productive? It's getting more confusing by the minute...

This concerns me a lot because my latest batch of Vit C contains HA, l-ascorbic and distilled water. I like this batch more than the previous ones with PG.

I have never heard this before. I always thought that the reason that you could not use Vitamin C and copper peptides together is because the Vitamin C is acidic and an acidic environment can cause the copper and peptides to break apart resulting in free copper in the skin which can lead to skin damage.

Many commericial c serums (IS Clinical, Skinceuticles and Cellex-C to name a few) contain zinc which is a metallic element so in at least some cases it is okay to combine metals with Vitamin C. I would find it hard to believe that cosmetic chemists at major companies would not know about potentially bad reactions between Vitamin C and zinc!

In reference to applying sunscreens after a C serum I would wait at least 15 minutes. I have never heard any warnings about applying sunscreen right after a C serum but I would wait for other reasons (I think it is a good idea to let any active ingredient sink into the skin before you going rubbing something over it which could dilute it and lessen it's effectiveness).

Concerning Vitamin C degrading hyaluronic acid, where can I get more information on this? Some c serums (examples ISC Super Serum, PSF C serums) contain hyaluranic acid and I would also find it hard to believe that the cosmetics chemsits at these companies would combine Vitamin C and hyaluronic Acid if there was a problem with combining the two.

BYRG unfortunatly I cannot help you with your anhydrous C serum. I have actually read all the stuff on the SmartSkinCare website and have even ordered the info packs from that site but I am not at this time into the DIY stuff.
