Telomeres were recently popularized – and legitimized – by a Nobel Prize winning team of scientists. Research on telomeres and aging has led to an ingredient called teprenone (sometimes marketed under the name of Renovage) cropping up in anti-aging products, potions and lotions.

Telomeres shorten every time a cell divides. When they become very short, they trigger cell crisis and cell death. In cosmetics, the objective not to lengthen the teleomeres, stabilize them so that at least they won’t shorten. Maintaining telomere length extends, we are told, the Hayflick Limit by one third. Renovage (made by the people behind Matrixyl) aims to do just that.

Here’s a round up of the Five Best anti-aging products that feature Renovage/teprenone. I should qualify this by saying that these are the best that we’ve tried out so far. I hope that this list will updated as we find even better – feel free to make suggestions.

Osmotics Renovage Cellular Eye Repair Cream ($78) This has another ingredient that may help extend the hayflick limit, carnosine. What makes it stand apart from other antioxidants is its potential ability to fight against, not just oxidative damage done by free radicals, but also damage done by sugar-related glycation. There are plenty of independent studies on  another ingredient here, aminoguanidine. It seems that it inhibits the cross-linking of proteins that cause signs of aging such as break down of elastin. Resveratol has been isolated from polygonum cuspidatum root extract, also known as Japanese knotweed.

Your Best Face Correct ($150 in the TIA shop). The reformulation of what I found to be an excellent eye cream included teprenone and also some of the latest heavy hitters known to cosmeceuticals such as the antioxidant lipochroman-6 and collagen building Syn-Tacks. The fascinating spin trap, a molecule that catches free radicals is sill included, as is Matrixyl 3000. Firmer skin, reduced crepiness, diminished lines as well as help for chronic dark circles have all been reported by testers. Your Best Face also added teprenone to its face cream Boost.

CSI Telomere Fine Line Repair Cream ($31.75). This little guy is very similar to another teprenone cream that costs $100. A simple formula with three good skin hydrators: squalane, hyaluronic acid and xylitylglucoside anhydroxylitol xylitol. Sure there’s a few fillers, but you can’t quibble at the price.

Jack Black Protein Booster Skin Serum ($60). Launched a year or so ago,  this covers all bases. In addition to teprenone and heavy hitters such as Matrixyl 3000. There are omegas, green tea and vitamins A, C and E.  Some of the botanicals are organic, although not sorghum bicolor stalk juice, interesting ingredient that you’ll be hard pressed to find in the mainstream and which is known to tighten the skin. In the mostly mediocre men’s skincare market, this serum is a standout.

Skinn Wrinkle Balm Night Treatment ($40). This comes in two versions. The dry-normal version starts with olive butter, shea butter, sweet almond butter, and soybean sterols, normal-combination lists lavender extract, sunflower seed extract, shea butter, and squalane as its most populous components. The overall picture of each is uniquely quite nice, with interesting inclusions like barley, wild yam, green bean, tomato, and noni extracts in one (dry-normal), and more mainstream botanicals, such as sandalwood, algae, rapeseed, thyme, and aloe, in the other (normal-combo).
