I was using Avalon's Vit. C serum without knowing its low concentration...thus not getting any results from it...
then I got some Vit. C serum from my mom (La Roche-Posay)
i don't know if LPR make good Vit C serum since I never heard anyone talked about it here on this forum...
just wondering if anyone know if its a good vit c serum? is it a low concentration vit. c serum?
i want to find an affordable vit c serum... apparantly alot of them are too exp. for me to afford.
LRP on the other hand is ok-priced ($40CAD) and i can get it locally... so no need to order it online...
thanks,
April |

| The ones mentioned here most often are the cellular skin rx, vivier and skinceuticals brands. I use the cellular skin rx one ($38USD)and like it very much. Some find it too slippery though. Whatever you buy look for l-ascorbic acid at a 10% or greater concentration, packaged in a dark bottle (amber for example), waterless formula would be preferable to keep the l-ascorbic acid from oxidizing. Good luck! |

| i like skinceuticals but haven't tried any other brands. I got a sample of LRP active c for eyes that I used for a month....I liked the feeling of it, but didn't notice any benefit besides hydration. |

I'm using Vivier and the results have been quite dramatic - but as I'm over 40 there was plenty for it to improve 
I started using it around a month ago, just once a day. Now I'm sure that my skin likes it I've started using it twice a day after reading recommendations here. I can already see that twice a day really speeds up the improvements. |

Vitamin C Serum by La Roche Posay is an EXCELLENT product. My mother is a Dermatologist and is the number 1 seller of La Roche Posay products on the west coast. My mother is the type of dermatologist that will not sell things she doesn't believe in. So I asked her why La Roche Posay's vitamin C is better than the rest (and I didn't tell her about this question on the forum!). She said that La Roche Posay has created a formula that effectively penetrates skin to a maximum depth. It is the penetrance of a product that actually makes it work. It also works in lightening skin. Secondly, they spent a lot of $$ on R&D creating a silicone molecule that leaves your skin feeling silky and smooth. (and it does)
I guess La Roche Posay wouldn't be talked about on the boards too much because it is only sold in Doctor offices in the United States (and online stores owned by doctors). I am by no way affiliated with La Roche Posay. I just love a few of their products (I use a lot of other product lines too!) and I think their Active C really works. ALSO, read this months In Style Magazine! They list the top 100 products to own and Active C is one of them!! Another one of my FAVORITE products is on there as well: Replenix by Topix. But that's a whole other story...! |

misskoslow,
I am so glad to see your post about Vitamin C Serum by La Roche Posay. I wanted to try it but not sure if the 5% C would have any effects on the skin since most people use 10% or more. I am also interested in the Avene YstHeal and Replenix by Topix but do not hear much about them. If you have time, please tell me more about them.
Thanks. |

| I used to use the celluar rx c and loved it. I've started alphaderma about a montha ago, and I know it has c in it too. Does anyone know if it's good to use a c serum with the alphaderma, or is that sort of redundant? |

Hi there!
Well I was talking to my mom about the difference between a 5% and a 10% concentration and the truth is that the difference is extremely small. The BIGGEST issue when it comes to these serums is HOW you put them on in order to get a maximum penetration. The way to accomplish this is to make sure to put on a pea size amount on when your face is damp. That way your face captures the moisture and the serum better. Therefore, the difference between 5 and 10 becomes almost void. (That's what I've been told anyway...and I love Active C).
When it comes to Replenix all I can talk about is the Serum. Topix (the company that makes Replenix) has some of the best chemists in the business. Topix is known in the dermatologic industry as a company that manufactures quality products. Their Cellex C line is fabulous too. Back to Replenix Serum - it has a great light feeling and leaves your skin feeling silky. It's a watery base - not as watery as some - but maybe I still wish it was a little tiny bit firmer. Either way it's the best product I've used in a long time and I'll definitely rebuy.
That's all I can say about it. I can't talk too much about the ingredient content. All I can say is that its light-weight, fast-absorbing and doesn't leave an oily residue on your face like some of the other serums that I have tried...
Hope that helps! |

The Cellex C product is in a water-based formula which I wouldn't recommend. Water has oxygen in it and it oxidizes the l-ascorbic acid. Once oxidized the l-ascorbic acid is useless and ineffective. Silicone encapsulated vitamin c like the la roche posay or skinmedica is protected from oxidation but makes uptake of c into the skin more difficult as the c is encapsulated in silicone and the silicone prevents complete absorption. If you can tolerate glycols (butylene,propylene) these are best since they increase penetration into the skin while stabilizing the C. This is the main reason I use the Cellular Skin Rx brand. It's a simple formulation - lascorbic acid and butylene glycol. That's it. No fillers etc.
Good luck! C serum is so good for your skin. I'm the #1 fan of vitamin C! |

How about Vivier and Skinceuticals? Are they as effective as Cellular SkinRx, do they have similar formulations? |

| I also have been getting great results from SkinCeuticals C(15%)+AHA. At $115.00 it is expensive, but it is the only skincare product that I won't give up, no matter what. I have changed a lot of products every month since being on this forum, but the SkinCeuticals Vit. C is a keeper! |

| FYI...the cheapest Vit-C serum is going to be one that you make yourself...you can buy all of the materials for about $15USD and it’ll be enough to make more bottles of Vit-C serum than you could probably use in your lifetime!! I just posted the recipe (again) under this link: http://www.essentialdayspa.com/forum/viewthread.php?tid=5445 |

you're welcome! Anything I can do to help. You know, the Dermatologist that owns SkinCeuticals was the man who started Cellex-C. When he left the company he took his C formulation w/ him. Maybe that's why SkinCeuticals is so much better than Cellex-C (at least that's my two cents). Anyone try the SkinCeuticals C+E? That's supposed to be amazing...I'm curious! |

Well, I started out using a sample of Vit-C serum from CSRx (a tiny vial that lasted me almost three months of daily use). I only made the homemade version this weekend, which means that I've only been using it for 2 1/2 days now. However, Vit-C serum has (in general) helped even out my skintone and fade lingering red marks/blotches from previous breakouts. Yes, the recipe I posted for the homemade version yields a 12% concentration of Vit-C. Somewhere on MakeupAlley, someone posted "conversion" chart that tells you how to make a Vit-C serum with a stronger or weaker concentration, but basically it boils down to adding more or less of the lysorbic acid (Vit-C) powder/crystals to the recipe. If you haven't used a Vit-C serum before, then please be advised that for some people it can be a bit drying, so be sure to followup by applying a good moisturizer after you've applied the serum and let it "sink in" for a few minutes (optimally, ten minutes). |

Oh, I'm soooo curious to hear how the homemade stuff works out, Carrie! I ordered vegie glycerin and have finally found the l-ascorbic acid crystals to order here in Canada. I got my glycerin and bottles herewww.cranberrylane.com and my l-ascorbic here http://www.healthmart2000.com/item112.htm
I can't wait to try this out! I'm going to pick up some ph strips too. I read you can up the ph to where it needs to be with baking soda, are you testing your ph? Does it feel like the retail sample you used?
This is fun! I'm going to pick up some blanched almonds too to make my own Cleansing Cream. |

Eeeekkkk!! The recipe from the MUA didn’t mention anything about PH!! I guess I better buy some PH strips, too. You know, I was surprised, thinking that my CSRx Vit-C serum would feel “lighter” (more water-like) than the homemade version, but I actually didn’t notice any difference: the homemade serum felt exactly the same, with the same amount of “slip” as it glided over my skin, so I think I’m going to keep the $38USD I had allotted this month to buy a refill of my CSRx Vit-C serum.... m, whatever shall I spend that extra $38 on??? Decisions, decision.... |

I would be curious to know the answer to this too.
Is Skinceuticals' vit C serum formulated along the same lines as Cellular Skin RX's serums?
Thanks,
Katie

FYI - there’s another recipe somewhere on MakeupAlley for a homemade Vit-C serum that uses strictly lysorbic acid and butylene glycol, but you have to order the butylene glycol from some kind of "science supply" place online (i.e.: the place where your high school science teacher buys all the lovely ingredients for those fun and exciting science experiments in chemistry lab!!), which is why I went for the recipe with the glycerin, as it's more easily/readily available at my local supermarket...although someday I'll probably bite the bullet and order some BG, since the CSRx formulation is my fave! |
