So i came across a list of antioxidants in typical anti aging serums, and i was just wondering what other antioxidants are used, because i heard that the antioxidants are what make your face younger by fighting oxidation and free radicals.

Here is my list so far of antioxidants... what others are there?

Long used to help protect the skin in creams and lotion, allantoin was thought to be a skin protectant. It has been called a "cell proliferant, epithelization stimulant, and a chemical debrider." Basically, it helps to exfoliate and stimulate new skin growth.

Alpha Lipoic Acid (ALA)
ALA is unique, as it is soluble in both water and lipids, so it easily penetrates into the skin. It seems to help protects Vitamins E and C, helping to boost their activity within the cell by "reenergizing" them. It is also converted in the skin into another chemical that has it's own antioxidant properties.

Copper Peptides
Copper has long been known to be important in the creation of collagen and elastin (again, important parts of the dermis), both of which are decreased with aging. Copper does have a bit more research than many other topical antioxidants, and some well design (aka- double-blind placebo controlled) research studies have shown improvement in fine wrinkles, hyperpigmentation and decreased photodamage. Copper increases the body's superoxide dismutase levels (see below). They even found a 17.8% improvement in skin thickness! Overall that does sound great, and copper is very appealing to add to products since it is non-irritating and pretty cheap to add to creams.

Dimethylaminoethanol (DMAE)
When used topically, DMAE has been found to increase firmness of the skin, likely because it helps to reduce some linking between proteins in the skin that happens with aging, as well as separate antioxidant properties.

Composed of glutamic acid, cysteine, and glycine, this little protein is found in all animal tissues, is one of your body's main antioxidants and is very decreased in the skin after skin exposure. Unfortunately it is water soluble, which means it does not absorb well when taken orally or applied topically. Not available in cosmetic products.

Grape and Grape Seed Extract
Proanthocyanidin, a very powerful antioxidant is found in grapes and grape seed extracts. While this antioxidant doesn't have strong evidence that it works topically (really, most of these things I'm listing don't have much evidence anyways), it was found to have strong effects on free radical damage of fat cells especially, as well as improved wound healing and prevention of tumors (both in mice).

Green and White Tea
Green Tea has some great things in it called polyphenols and they are one of the most widely studied anti-oxidants on earth. Polyphenols are a very large and diverse family. There are literally thousands of them, and they are all found in two. The 4 major ones found in tea have long complicated names, but they are shortened to ECG, GCG, EGCG and EGC. Confused yet? The EGCG is the main polyphenol that is responsible for anti-oxidant activity in both green and white tea and it is the most potent. It is important to know which polyphenols are included in a formulation, and to what concentration. The most effective products will contain 50 to 90% polyphenols and will be brown.

EGCG does offer photoprotection. This has been seen in mice with both oral and topical application, as well as in human skin. It is dose dependent (meaning, more ECGC will result in more effects), resulting in a decrease in redness, sunburned cells and less DNA damage after UV exposure.

Note that most of these studies were done specifically with ECGC as the ingredient. There are thousands of polyphenols in green tea, and most products on the market that contain green or white tea are not of a high enough concentration to demonstrate that they work. Look for ECGC ((-)EpiGalloCatechin-3-O-Gallate) and concentrations over 50%.
