vitamin c collagen serum (PBS) and collagenase inhibitor (Ci) were added to the diet. The serum was then diluted with 1 ml of 0.5% Tween 20 and incubated for 30 min at room temperature. After incubation, the serum samples were centrifuged at 3000 g for 10 min and the supernatant was collected.
The serum sample was centrifugeed for 5 min, and a sample of serum from the same individual was used for the analysis. Serum samples from different individuals were analyzed by using a Bio-Rad ELISA kit (Bio-RAD Laboratories, Hercules, CA). Serums were separated by SDS-PAGE and stored at −80°C until analysis by BioRad. Protein content was determined by real-time PCR using the TaqMan SYBR Green Master Mix (Applied Biosystems, Foster City, California).
, where the mean of the two groups was calculated as the sum of two independent samples. For the determination of protein content, serum protein was measured by radioimmunoassay (RIA) using an ABI Prism 7000 (ABI, Cat. No. 070-00-01-0) according to manufacturer’s instructions. All samples (n = 10) from each individual were tested for protein concentration by RT-PCR using TaQMan (Invitrogen, Carlsbad, Calif.) according the manufacturer. RT‐PCRs were performed using primers: 5′-GCTTGGTCTGGCTGTTCTCATGCCTCCGAGC-3′ and 5′-CTCTCCCTTTCCCCTTTTGTCGAAG-2′. Taqs were used to amplify the PCR products. A total of 10,000 priming cycles were run to obtain a final product of 5,500 bp. PCR amplification was performed in triplicate. To determine the relative abundance of different proteins, a total amount of proteins was quantified by the use of a Taqlite (Qiagen, Valencia, Spain) with a specific gravity of 1.0. Each sample (10) was analyzed for its relative protein abundance using two different methods. First, samples with the highest relative abundances were compared with those with lower relative proteins. Second, protein levels were determined using real time PCR. Real-Time PCR was conducted using Primer Pro (Promega, Madison, WI

The following is a list of the most common vitamin C supplements that are recommended for use in the treatment of acne. These are the products that I have personally used and have found to be effective. I am not a doctor and do not recommend any of these products for the diagnosis or treatment, but I do recommend that you consult with a dermatologist if you have any questions about the use of any vitamin or mineral supplements.

Best vitamin C serum
The Vitamin C Serum is a serum that contains vitamin c, which is an antioxidant that helps to protect the skin from free radicals. It is also a great way to boost your skin’s natural antioxidant defenses.

Best vitamin C serum recommended by dermatologist
The vitamin c serum is a great way to boost your skin’s natural antioxidant defenses. It’s also a good way for you to get your vitamin D levels up.
, a vitamin-C-rich serum that’s made from a combination of vitamin A, C, and E. The serum contains a blend of vitamins A and C and a mix of E and A. This serum has been shown to help boost the levels of the antioxidant vitamin E, which is essential for the production of collagen, the skin-building protein that helps protect your cells from damage.
