This is more or less true. The main purpose of Vitamin C is to boost collagen production, as well as being an antioxidant which will protect the skin from further damage. It only slightly exfoliates because it is acidic, but that's not the main objective, and it's not what makes this serum profitable.
I've tried applying lemon juice on my face in the past, to reduce slight hyperpigmentation. Lemon juice has a pH of 2.0 and I could still tolerate it, even if there was occasional stinging and redness. I stopped using it because it didn't seem to have any effect whatsoever, and was only irritating.
The serum I'm planning to make has a pH of around 2.5, which is in fact 5 times less acidic than lemon juice (the pH scale works that way : compared to a substance with a pH of 2.0, a product with a pH of 3.0 is x10 less acidic, a product with a pH of 4.0 is x100 less acidic, etc.). As a comparison, orange juice has a pH of 3.0. So I'm fairly confident I'll at least tolerate the acidity to some degree (without causing mad damage before I realize it's too irritating I mean). Also, it doesn't take long for the skin to absorb the Vitamin C, so you can simply apply the serum and wash it off after 30 minutes to avoid unnecessary irritation on the outer layers of the skin. Once Vitamin C is absorbed by the skin, it stays there and delivers its benefits for 3 days or so.
Another important thing is that you need to be careful not to use Vitamin C that has already oxidized ; that could amplify the negative effects, as well as having no benefit whatsoever. It's important to store the serum in a sealed/opaque container, and keep it in the fridge for a maximum of one week (once the serum turns orange, it has already oxidized). Distilled water should also be used, as the minerals contained in tap water will also oxidize Vitamin C. That's why I'm planning on using glycerine instead (it could also help reduce irritation).

Some reviews :
(The serum is rated 4.5/5 overall, so surely some people see benefits. You'll notice some who rated it 1/5 though.)

Dancing_Doll's update in the Teeth Whitening thread made me remember that I should also offer an update about my Vitamin C serum.
At first, I just ordered a random Ascorbic Acid powder from an online pharmacy (the kind that's meant to dilute/drink as a Vitamin C supplement), but I figured out it wasn't really appropriate. These powders contain some minerals to reduce the acidity, so the Vitamin C can't really penetrate the skin as the solution wouldn't be acidic enough.
I then ordered professional-quality ingredients from an online 'lotion crafter' company instead (click here).
For about $50, I got:
- Ascorbic Acid powder
- Vitamin E serum
- Ferulic Acid powder
I ordered these ingredients to create a powerful/awesome Vitamin C serum, exactly the same solution as this company sells: C E Ferulic.
Yep, you read that right... $157 for only 30ml. With my $50 order, I calculated that I could produce around 18-20 bottles of 30ml. That's nearly $3,000 worth of this serum that I can produce for only $50.
There are many DIY sites who offer the recipe of this serum, with the exact proportions and everything that you need to know.
The reason Vitamin E and Ferulic Acid are added is mainly to stabilize the Vitamin C so that it doesn't oxide rapidly and can penetrate the skin more effectively. Vitamin E is also just great for the skin on its own, and can help render the solution a bit less irritating.
Anyway, right now I'm still using Hydroquinone to fade some spots on my face (until late August), but I'll create this serum as soon as my treatment is over. It's not really recommended to use other skincare products in combination with Hydroquinone, so I'm being careful.
Damn, it's fun to combine my fashion and nerdy interests together. I feel like an handsome mad scientist.
I'll keep you informed...
