as a topical for skin tightening?
According to Skin Biology, I think that is what they are saying:
Read below:
Fibroblasts, lysyl oxidase, copper 2 and vitamin C
Biological skin tightening occurs as the skin's repair cells, the fibroblasts, pull collagen strands together. Then they are biochemically attached by the fibroblast in a way that keeps the strands elastic and soft. The fibroblast uses an enzyme - lysyl oxidase - which needs both copper 2 and vitamin C to link the collagen strands together.
Adequate levels of both copper 2 and vitamin C are essential for wound contraction. You cannot get skin tightening without high levels of both copper 2 and vitamin C )ascorbic acid) in your skin. Copper 2 is best supplied from SRCPs applied to the skin surface. Vitamin C levels in the skin are easily by increased by taking at least one gram daily as a supplement. It is difficult to get vitamin C through the skin except at a very low pH of about 2.5 (very acid).
Concomitant use of hydroxy acids, such as salicylic acid and lactic acid, that remove the older cells on the skin's surface also helps with skin tightening. The hydroxy acids produce a very mild skin damage as they remove older skin cells but this helps the renewal process, probably by increase the numbers of the skin repair cell, the fibroblast.
The elastic fibers of the skin, collagen and elastin, are produced by a skin cell, the fibroblast. Lasers, microwaves, and heating lights do not produce collagen.

So I already ahve V-C CRystals to make my own serum so now I am just adding some to my OJ in the AM.
I do wonder how effective Vitamin C topicals are b/c they can degrade so easily and other things can interfere. Also how does one really know the PH of these serums we purchase? so maybe making sure you get 1 gram daily as a SUPPLEMENT will just enforce what you are trying to do/
I would love to hear others thoughts on this.
This page has amazing before and afters:

| Well, I guess I'll make sure I take my vitamin C supplement all year round and not just in cold season from now on! |

| Best to eat your fruit, vitamins are much more easily absorbed from nutrients than from supplements. |

Yes, but you cant get 1g or 2.5+g (which should be the recommended dosage) with fruits and vegetables.
But for this very reason you should take formulations containing bioflavonoids. |

I would do both. I heard that your skin is always the last organ to receive any nutrients so it's best to do both.  |

Yes
And there was a thread somewhere here discussing the types of topical vit C. I advocate ascorbyl palmitate together with ascorbic acid for topicals, because it binds with the fat layer in the skin and IMHO lasts longer. I have to dye something one day, i'm just too lazy now |

I really know very little about copper peptides but must admit that the stuff on the skinbiology website is very interesting.
Concerning the claim about oral vitamin c easily increasing vitamin c levels in the skin I am skeptical. I am not saying it isn't true I am just saying that I would need to do a lot more research and see some proof before I would accept that statement.
I found this on the IS clinical website:
Actions and Uses—Vitamin C is one of the most essential substances in skin. It is transported to the skin after oral ingestion or its levels can be supplemented with topical application. Oral ingestion of antioxidants, in general, lead to about 1% of their amount being deposited in the skin. (Oxidants and Antioxidants in Cutaneous Biology, Curr Probl Dermatol, 2001, Karger:Basel, 29:157-164) Topical application is much more effective at producing higher levels of Vitamin C, providing an effective topical preparation is used. For a variety of factors relating to modern life, the skin of the majority of us is relatively deficient in Vitamin C. It is preferable to replenish this Vitamin C first before beginning therapy with combination topical antioxidants, such as Vitamin C plus Vitamin E, or C plus E plus a number of other plant-derived antioxidants. (to be published re NIH/NCI grant #1 R43 CA83538-01A1, communication with MM Omar) When the Vitamin C has been replenished in 4-12 weeks, therapy with Vitamin C in combination with other antioxidants may be started.
I am not sure if this would support or contradict the claim about oral vitamin c easily increasing skin vitamin c levels but I think that it is interesting.
Both IS Clinical and Skinceuticles say that the ph of a vitamin c serum has to be less than 3.5 to be effective. An ad that I read for Mychelle products said c serums had to have a ph of 2.0 to 3.5 to be effective. You can ask companies what the ph of their c products are and to be safe you can test it with ph strips. I myself often wonder about the stability of c serums.
I myself stopped taking vitamin c supplements other that what I get in my multivitamin, but I imagine that it would not hurt.
I have read (on this forum and elswhere) that topical vitamin c and copper peptides should not be applied at the same time. Most of what I have read says to wait at least 12 hours between applying the two. I haven't looked into this to see if it is true but if I were using both vit c and copper peptides I would be concerned about it. Also I think that the reason that vit c and copper peptides should not be combined is because of the acidity of the C. If this is true then copper peptides and AHAs should not be applied at the same time without first neutralizing the AHA. I could be wrong but I thought I would raise the point because it seems to be a concren. If anyone has more info. about these potential bad interactions I would love to hear it.
This is turning out to be a long post. when I think about something my mind tends to generate a lot of thoughts.  |

| I do tend to use vitamin C in the morning, and my MD Forte at night, so that fits in with your theory there. I can''t remember where I heard that they should be applied separately though, so not sure if there's science or just habit behind it. I'm sure someone here will know though! |

I have also read, in several reputable sources that copper and Vitamin C are in no way to be used together and in fact no closer than 3 +/- days between the use of one or the other. Together, I believe they can create skin damage.
