The important thing when purchasing a topical vitamin C is that you choose one in which the molecules are small enough to penetrate the skin. For as long as I can remember, Cellex C has been referred to as the "grandfather" of this science, and for good reason. According to SkinStore.com, Dr. Lorraine Meisner, a cell biologist and cytogenecist and Dr. Michael Schinitsky, a pathologist, created this serum. Those who don't have quite the same level of knowledge, education and expertise develop many of today's skincare products.

Vitamin C helps to rid the face of unwanted fine lines and wrinkles, firms and smoothes skin of the face and neck, and improves color, tone and texture. Skincaredictionary.com helps us to understand why by defining it this way: Vitamin C is the only antioxidant that has been proven to increase collagen synthesis. Collagen synthesis is essential to maintain healthy skin. Studies show that collagen decreases with aging and that photoaging accelerates the decrease. L-ascorbic acid serves as a signal, relaying a critical message to collagen genes to synthesize collagen, as well as being a cofactor for two enzymes important in collagen synthesis.

Remember, don't choose just any vitamin C serum, gel or cream as it must have been developed correctly and scientifically in order to penetrate effectively. Otherwise you're purchasing a product that is using a vitamin C for label purposes only and does not have the ability or strength to get in through the epidermis to do its job.

Remember, "grandfather" always know best!
