Hi all,

I need some Vitamin C serum recommendations. I want one that is affordable but will still give me the benefits of using Vitamin C. I would use Skinceuticals, but I'm pretty sure that is really expensive.

Also, I need one that uses one of the more stable forms of Vitamin C in its formula, such as:
-Magnesium Ascorbyl Phosphate
-Tetrahexyldecyl Ascorbate
-Ascorbyl Methylsilanol Pectinate
-Ascorbyl Palmitate
-Sodium Ascorbyl Phosphate

From what I've read so far, ascorbic acid and L-Ascorbic acid are unstable forms of Vitamin C, so I would rather not use a serum that has those forms.

I would really appreciate some recommendations. Thanks in advance, everyone!

I love this one: https://www.sweetprana.com/product/sunshine-superstar-serum/

It contains Magnesium Ascorbyl Phosphate. It also contains Hyaluronic and Ferulic Acids. And it's affordable.

Thanks for the recommendation, ngeisler! How long does this last you?

Also, does it have a color to it?

I tried a Vitamin C serum before that was a bright orange color and it stained my skin orange, which was distressing. And I confirmed with the company that it wasn't old, it was just an orange color for some reason. So I need something white or clear that won't stain my pale skin.

You need to use your c serum up within a couple of months. It should be clear, with maybe a pale yellow tinge. No company would make their c serum orange - it's a clear sign of oxidization. I don't buy the "it's just orange" excuse. The moment you open the bottle and air hits the serum, the clock starts ticking, which is why it's insane to spend a ton of money on c serum. If it turns solid yellow, orange or red, toss it.

Yeah, it's a bit strange. The company says it's because they also use carotene in the serum. Either way, that makes it too hard to tell if the serum is old or not so it seems like a ridiculous choice.

Thank you for the info!

Timeless CE Ferulic lasts about four months but decant half into a separate bottle and refrigerate both. That way only one gets exposed to air frequently. Great value for the money - about $25.

Wow, thanks Softskin! That's definitely a great value and even includes Vitamin E and Ferulic acid like I was hoping for as well. Do you have a specific source you use to get yours?

Also, what's your recommendation for decanting the serum? I want to make sure I have an opaque bottle that won't let light into the serum or anything.

Thanks again!

Neostrata has a 10% vitamin C serum that comes in capsules so it is not exposed to the air.
It is the only one that works well for me so far.

Body Shop has a similar vitamin C product and thought I would try it since it was on sale, and it only worked ok on me.

The Neostrata product has no colour, maybe a store can give you 1 or 2 caps to try.
The body shop, when I went the girl was nice enough to give me 4 or 5 capsules- so I had enough for almost 1 week!

I tried Skinceuticals, Murad and a bunch other vitamin C products.
So far Neostrata is the only one I buy all the time when I run out.
I might get the body shop one it they have a 3 items for $30 sale...

I often shop at Skinactives.com. They have a Vitamin C Serum that also contains E and Ferulic Acid along with some additional good actives for your skin.It sells for $15.50 per ounce.

The vitamin C powder from philosophy is very easy to use and store. Just add it to your serum or face cream then you have your own vitamin C products.

I like anhydrous serums because they are extremely stable. A good one is the CSI 12% l-aa serum available from Vitacost. It's only 2 ingredients, butylene glycol and l-aa. Extremely stable, would not go bad for a long time. It's less than 20 dollars on Vitacost and they often have sales.

The body shop has some vitamin C thing in capsules, similar to Neostrata and if lucky you can get it on sale for $10 when they have a any 3 items for $30 sale.

But staff in the store did give me 2 capsules as a sample to take home....for free Smile
-just go and ask them.

OMG I thought I was the only one who knew about this brand! I love Martiderm Photo Age toooo. Most Vit C in the market are too acidic and sticky for me except Martiderm. The serum comes in 2ml vials to prevent oxidation.

Forget about Magnesium Ascorbate which is ester form of Vit C or tetrahexyldecy ascorbate which is the oily form. Neither will do anything for you.

Look for L-ascorbic Acid 10-15%

Seriously? Forget? Why? Do you have any evidence to corroborate your statement?

My statement is based on my experience using both manufactured products and isolated chemicals sourced from Skinactives, etc

I have been doing it for 15 years.

All the research showing Vit C's ability to be anti-oxidative, collagen-producing, and pigment-reducing effects is based on L-ASCORBIC ACID. Even if you use one of the Vit C derivatives, presumably for the purpose of increasing stability (eg adding ferulic acid), for any of the AA derivatives to be effective, they need to be able to release or be converted back to AA.


What that means is, play with Vit C any which way you want, the only structure in which it will function is Ascorbic Acid. You are merely swapping its structure around for the sake of stability but lowering its efficacy because ultimately, the skin needs to convert it back to AA. During this back and forth conversion, much of the effectiveness is lost. Furthermore, using Ascorbyl Tetraisopalmitate as an example, it carries 1 part AA, four part tetraisopalmitic acid, a buttery substance. So whatever you are applying on to the skin, you are only getting 20% of what you really want (vit C), the rest is "butter".

None of those Vit C derivatives I mentioned in my previous posting are acids (-Magnesium Ascorbyl Phosphate
-Tetrahexyldecyl Ascorbate
-Ascorbyl Methylsilanol Pectinate
-Ascorbyl Palmitate
-Sodium Ascorbyl Phosphate). None of them could donate a proton in aqueous solution like an acid would.

The best cosmeceutical companies that make fantastic Vit C preparations such as SKINCEUTICALS, ULTRACEUTICALS, IS CLINICALS and of course, CELLEX C, the company that started it first, rely solely on L-ascorbic acid 15% at pH around 3.
Those formulations have not changed for 10 years and continue to enjoy a loyal following, including me.



So what is your statement, ko6kin.?

I'm still loving my Vitamin C Serum from Pure Skin Formulations. I've been using it for years. Every time I go off it or switch to try something else, I notice a difference in my skin for the worse. So now I just don't mess with a good thing. It's 15% L-ascorbic acid & it's stabilized so it stays clear to the last drop. I think it's BETTER than skincueticals & is only $46. And best of all you can get it right here from EDS! 😉
