SIRTUINS: These are protein enzymes and they help repair damaged cells. They are known to make cells live longer in the lab. They also increase collagen production.

PRO-XYLANE: This is basicallly a super-duper moisturizer. It's a form of hyaluronic acid that attracts water to cells and holds up to 1,000 times its volume, keeping skin plump and making lines less apparent. It also leads to the production of more collagen, which keeps skin firm and smooth.

GROWTH FACTORS: Growth factors are proteins and hormones that instruct cells to build collagen and increase formation of blood vessels. A study in the Journal of Drugs in Dermatology showed that they substantially reduce wrinkles around the eyes and mouth.

NIACINAMIDE: A naturally occurring form of vitamin B3, niacinamide helps to repair cell DNA. DNA naturally fixes itself, but niacinamide speeds up the process. It helps fight sun damage,and may have anti-cancer properties.

PEPTIDES: Some peptides help shrink bags under the eyes by improving lymphatic circulation, some relax the muscles that cause wrinkles, and others stimulate collagen production to firm skin.

ALPHA LIPOIC ACID: alpha lipoic acid (ALA) is a powerful antioxidant that helps fight free radicals that damage skin. Because it is both fat-and water-soluble, it is able to penetrate deep into the cells for more effective anti-aging benefits. In a study in the British Journal of Dermatology, it reduced wrinkles and smoothed skin by about 50 percent in middle-aged women.

LACTOBACILLUS: lactobacillus helps skin maintain a balance of moisture and bacteria, which helps spped up skins healing process. 

PHLORETIN:  Phloretin is an antioxidant that comes from apples. When it's combined with vitamin C and ferulic acid, it's been shown to penetrate the skin and stop the formation of brown spots and wrinkles. It also protects against DNA changes that lead to some skin cancers.

ISOTRETINOIN: The main ingredient in acne fighting drug Accutane is isotretinoin. As well as fighting acne, the low-dose pills can improve wrinkles, skin tone, and hyperpigmentation and its effects may last for a few years.

AMINOGLYCINE: In hair-color formulas, AminoGlycine can change hair's pigment (including grays) without compromising its keratin layer (unlike ammonia), so it doesn't damage hair.
