| Thank you Kassy for posted your recipe. I'm wondering if adding the ferulic acid will stablize the L Ascorbic acid, at least that is what I've been reading since I saw your recipe posted. |

| Yes it definitely will stabilize the LAA, and it's a great anti-oxidant to boot. |

| I am curious about skinactives, so many people have mentioned this website. I checked it out and there are a few ready made products I would like to try. Can anyone comment on their ready made products? I tend to stay with more natural ingredients in my routine but need something to fight those darn nose to mouth lines, maybe the 'lets make collagen' serum? Thanks for any comments. |

I love skinactives and would highly recommend DMAE(it tightens) and Let's Make collagen. Everything I have gotten from skinactives has been great for my skin. My only regret is that I am just now finding out about it.

Can you use DMAE aloe or is there a recipe to tighten skin? |

Blesstd,
My recipe is reaaally simple, that's why I like it! It's just the tetra (long name) vitamin C and rice bran oil. It's 10% of the tetra vitamin C. I also recently added some argan oil to it. You can use any carrier oil that your skin likes. Argan oil is supposed to be great for acne prone skin, it's the latest thing. Rice bran oil is also supposed to be good for acne prone skin, it's rich in vitamin E and highly stable and it's cheap, so that's why I started with rice bran oil.
I don't really recommend using it in the morning. It is an oil, after all. All I use in the morning after cleansing is sunscreen.

KassyA, THANK YOU for this very thorough post on your serum. This is just what I was hoping to learn being that Carekate's recipe was quite some time ago. It's creative that you thought to add the Remergent DNA cream! I am just starting to read-up on the Remergent DNA serum and Barrier cream after seeing it mentioned in that skincare book (I can't remember the name and already returned it to the library but it was discussed on the skincare board.)
Nimue, would you mind sharing your recipe too? When using the tetrahexyldecyl ascorbate in an oil base, do you find it absorbs easily or does it feel oily? I'm just wondering about using it in the morning under my make up.
And then I came across a thread on the Skin Medica Vit C Complex. I guess depending on our individual preferences - cost, convenience, etc. - determines the method we try.
I think I'm on "information overload"  at the moment.
Many thanks again for sharing your expertise! |

| Can you get all ingredients for Vit C serum from skinactives? Im having trouble finding the amber jars and the propylene glycol from there. Is there any one website that has everything?? I just want to save on shipping. Im just doing the simple serum Pure Vit C, Propylene and distilled water(which I can get from the grocery store of course) |

1/2 vial Ferulic Acid
1/2 capsule of MSM supplement (be sure it's one with NO fillers!)
6 drops of Vitamin E oil |
My question is: is this the vitamin c that is oil soluble and is much more stable? |

No. L-ascorbic acid is the water soluble vitamin C. Most vitamin C serums use this kind of vitamin C. The THDA (Tetrahexyldecyl Ascorbate) is oil soluble and very stable.
Not to say thatl-ascorbic acid is bad exactly-it's up to you to weigh the pros and cons. HTH!

Nimue, just curious - why ascorbic acid is bad?
Here is info from SmartSkincare web site:
"Vitamin C (L-ascorbic acid) is one of the relatively few topical agents whose effectiveness against wrinkles and fine lines is backed by a fair amount of reliable scientific evidence"
http://www.smartskincare.com/treatments/topical/vitamin-c-vitamin-e-ferulic-acid.html
Is it wrong  ?

sherry; The recipe I provided has LAA + a small amount of THDAA compliments of the Remergent DNA OR the 303 serum. In my opinion they are more powerful when used together.
Nimue; You are correct about the THDAA being more 'stable'. Unfortunately the stability is what keeps it from penetrating well into the cells where it's needed.
L-Ascorbic Acid is most definitely the most effective form of vitamin C your skin can get. (Just check the studies on PubMed etc.)Combining the two forms, while keeping the PH under 3.5, is the best of both worlds in my opinion.
For those of you making your own serum, just try the recipe I posted. I promise you won't be disappointed. (Just be sure your MSM passes the no filler test though, or leave it out.) |

But I didn't say that it's bad!  I just said that it's less stable than oil soluble vitamin C, which is true. The relative unstability is a negative though... I've never even tried a vitamin C serum with l-ascorbic acid so I'm just going by what I've read. It's also true that l-ascorbic acid has been documented as an effective anti-ager.

| So basically its better to use Tetrahexyldecyl Ascorbate(in place of L-absorbic acid), Propleyne and distilled water for a basic Vit C serum? |

You might want to re read this thread....
It's "best" to use a combination of the two I believe.........I also believe that if it comes down to a choice of the two, L-Ascorbic Acid is the best choice for really making the most impact on our skin.
L-AA:
Highly degradable ..... Yes
Highly effective and absorbable....... Yes
THDAA:
Highly degradable......NO
Highly effective and absobable ... NO
So now you just have to find a serum that incorporates both LAA + THDAA, in a base that will allow it to penetrate and also keep it more stable.....
HELLO.........I gave you guys the perfect recipe, and it didn't cost you a small fortune..
One of these days you guys will believe "something" I have to say....  ...In the meantime I'll continue to chant my....
HUUUU YAAAAH without ya'll..... |

I agree that l-ascorbic is the best choice for anti-aging benefits. It's a problem for manufacturers to make good and stable C serums with L-AA because it oxidizes easily, but I think it's a great choice in DYI-ing because you can make small batches frequently and avoid oxidation. |

I believe the ideal routine is to apply a serum with 10-15 % vitamin C once a day. If you apply it more often, cut back on the frequency. If the concentration of vitamin C in your serum is stronger, reduce the percentage.
This should not cause lines, but prevent the formation of new lines. HTH. |

YEP!
VITAMIN C SPRAY FOR BODY
Put 1 tsp of LAA into 2 oz (yields about 8%) of distilled water in a spritz bottle, add a few drops of witch hazel and shake till dissolved... Keep refrigerated, and make a new one once a week.
A little goes a long way so use sparingly. When fully absorbed, apply your moisturizer or sunscreen.
You can add more LAA if you want it stronger, I find the above sufficient without drying me out. |

Tetrahexyldecyl Ascorbate is 'oil' soluble, so somewhere in your formulation you have to have an oil, silicone or emulsifier.
If you want to keep it really simple, you can use "KY Chafing Powder Gel" as the base. I'd also suggest adding the contents of 2 vitamin E gel tabs to it.
Please don't be afraid of L-Ascorbic Acid.. It really is a power house for the skin. You can also use both forms of C together for a very nice 'more' stable formulation. |
