Newest Anti-Aging Ingredients(you should be using, if your over 50)


1. Sirtuins: These protein enzymes help repair cell damage and so far, are the only ingredients known to make cells live longer in the lab. They may ramp up collagen production, too.

2. Pro-xylane: This mega-moisturizer is a long-lasting synthetic 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 increases the communication between cells (a function that normally declines with age), which leads to the production of more wrinkle-fighting, skin-firming collagen.

3. Growth Factors: They sound like part of the stimulus plan, but growth factors are actually proteins and hormones that instruct cells to perform tasks like building collagen and increasing formation of blood vessels. A study in the "Journal of Drugs in Dermatology" showed that they substantially reduce wrinkles around the eyes and the mouth.

4. Niacinamide: A naturally occurring form of vitamin B3, niacinamide kicks various into high gear to repair cell DNA. And while everyone's DNA fixes itself, niacinamide seems to make the process happen faster--like a couple of cocktails on a first date. In addition to fighting sun damage, it may have anti-cancer properties.

5. Peptides: Some peptides are believed to shrink bags under the eyes by improving lymphatic circulation, some relax the muscles that cause wrinkles, and others rev up collagen to firm skin.

6. Alpha Lipoic Acid: Free radicals get their butts kicked by alpha lipoic acid(ALA), one of the most capable antioxidants around. But ALA does something that its antioxidant brethren don't--it is both fat-and water-soluble, meaning it can work inside the cell and and in the cell membrane to achieve some serious anti-aging effects. In one study in the "British Journal of Dermatology", it significantly reduced wrinkles and smoothed skin--by about 50 percent--in middle-aged women.

7. Lactobacillus: A probiotic, lactobacillus maintains the skin's protective balance of moisture and bacteria--kind of what health-food-store yogurt does for your gut. On your face, it plays a part in speeding up the healing process--especially after peels and other procedures that strip the skin of healthy bacteria.
8. Phloretin: Extracted from apples, phloretin is an antioxidant. And when it's combined with vitamin c and ferulic acid, it's been shown to penetrate the skin and interfere with the formation of brown spots and wrinkles. It also protects against DNA changes that lead to some nonmelanoma skin cancers.
9. Isotretinoin: The main ingredient in Accutane, isotretinoin is an oral retinoid that's an established, respected acne-fighter. What's new is the low-dose pills (20 mg), which can improve wrinkles, skin tone, and hyperpigmentation. Best of all, its effects may last for a few years.
10. Aminoglycine: In hair-color formulas, Amino-glycine can change hair's pigment (including grays) without compromising its keratin layer (unlike ammonia). The result? Hair doesn't end up dull and damaged after the process. Another plus: It works in just 10 minutes, as opposed to the usual 20.
11. Polyfluoroesters: These are, very simply, a godsend for frizz sufferers. Unlike silicone, they tame fuzz without weighing hair down; instead of sitting on top of the hair, they plug the gaps in each strand's cuticle, preventing moisture from penetrating the shaft. They work especially well on aging hair, which can become limp and brittle (and therefore more prone to breakage and frazzled ends) with time.
