Does anyone else use Sarah Vaughter's recommendations for applying Vit-C mixed into hot water (5% solution) to the skin a few times a week? My problem is that I overnight get yellowish bedding and it looks horrible. I do wash bedding weekly, but don't want to have to do it every couple of days.
What do other people do about this? |

Here's my thoughts FWIW Needl:
• LAA is so inherently unstable that something has to be used with it to stabilize it in a formula. Ferulic acid, vitamin E and other ingredients do this. Sometimes simple isnt the most effective.
• Are you using it directly before bedtime? Using it in the morning could work better but then this preparation would rub off onto your clothes. You arent the only one who has mentioned this problem.
• Are you washing this stuff off before bedtime? |

Thanks Fawnie
I've been putting it on at bedtime for the entire night. I understood that Vit E is oily, but Vit C can't get through oil? |

With the help of emulsifiers and penetration enhancers a C serum with a bit of oil works. Skin likes oil and lecithin and takes a serum up more efficiently that way. This explains:
"Although Vit. C alone can provide photoprotection, it works best in conjunction with Vitamin E (Vit. E), which potentiates the action of Vit. C four-fold. Hydrophilic Vit. C helps regenerate Vit. E, a liphophilic antioxidant.[1,3,5,6] Thus, Vit. C and Vit. E together protect the hydrophilic and lipophilic compartments of the cell, respectively. Vit. C and Vit. E synergistically limit chronic UV damage by significantly reducing both cell apoptosis and thymine dimer formation.[3,6]
A combination of 0.5% ferulic acid (a potent antioxidant of plant origin) with 15% Vit. C and 1% Vit. E can increase the efficacy of Vit. C eight-fold.[3] It was noted that this triple combination was very useful for the reduction of acute and chronic photodamage, and could be used for prevention of skin cancer in the future.[3]"

Update:
I ended up writing to Owndoc about this problem, and the staff member replied that rinsing it off after half an hour would still allow absorption. This has solved the messy sheet problem. I do notice that any specks on the wall or fabric are yellow by the next morning (but it rinses off them easily), so this stuff clearly oxidizes quickly. (L-ascorbic acid and hot water mixture, as per Owndoc instructions).
I'm hoping that the half hour allows enough to penetrate, and rinsing the rest off the skin surface will prevent on-skin oxidization. |

I've been doing the same and haven't really had that problem and I'm doing 20%. The thing is that I wanted to see if simplest method worked before adding anything to the mix and the results, at least for me, have been fantastic. Much better than all the C serums I've bought.
I do a small enough amount to stay fresh and whether this is the right thing to do or not; I follow it with a few drops of Vit E. I thought this might break me out but not so far. It seems to sink right in.
I do it every other night and Retin A the other nights.
I'll probably expand the recipe to include Ferulic Acid and e but since the results are so apparent I'm not in that big a hurry. I will stay away from preservatives and continue to keep it fresh and continue the DIY. It's not that much trouble. |

Tigerlily, do you mean you rinse off after half an hour too? And what brand of Vit C do you buy? I just ordered a kilo and then found out that the pH of that product is supposedly 6.4 in water. The pig skin study says it must be 3.5 or less to penetrate: http://www.ncbi.nlm.nih.gov/pubmed/11207686
Wondering what to do... |

No, I leave it on all night.
And do you mean the C you got from Sarah was that high in water or another dealer?
I started with Sarah's and now have been using a dealer on Ebay with no problems..
I'm not sure how to lower PH when it's that high so maybe you might contact the dealer you got the C from.. |

| I'm buying from an NZ trader, as it's cheaper this way for a big quantity. I've contacted her about this issue, and she says the undiluted powder is about pH 2.5-3.0 (so I guess for a serum without much water that should work) and she uses it for serum herself. Here is her simple recipe if anyone is interested: http://www.fittoblog.org/2012/08/diy-face-saver.html |
