If you'd asked me six months ago if I could imagine the day when I could put together a Truth In Aging's Five Best picks for eyelash growth products, I would have arched my (moth-eaten) brows quizzically. This roundup is the result of a lot of research, trial and error and the fact that some of the manufacturers (such as Jan Marini) have made a humungous effort to reformulate their products so that they not only work, but are safe. Thanks to all of this I have brows that would be the envy of Brooke Shields and plenty of lashes to bat.

One of the best finds had been right under my nose for months. I've been using Skin Biology's Folligen every now and then (with great success) to ensure that I don't have thinning-hair-with-age syndrome. Folligen is based on copper peptides, which are proven to strengthen the hair follicle and extend the hair growth cycle. Someone in the TIA community posted a question about whether Folligen works for eyelashes and brows as well as the hairline. I gave it a try and it works extremely well. In short, its a bit messy and you'll need to supply your own eyeliner brush. It is worth it though - I saw eyebrow and eyelash growth in only a few days. Plus you can't quibble at the price (newsletter subscribers and VIPs get a 10% discount at our store).

The new Marini Lash confirms its maker, Jan Marini, as the queen of eyelash growth products. The new Marini Lash is free of prostaglandins - the glaucoma drug that, until recently, powered most eyelash growth products and was associated with side effects that could harm the eyes and change their color. The main ingredients are moisturizers, sodium hyaluronate and hydrolized glycosaminoglycans. According to a study published in the British Journal of Dermatology, the extracellular matrix of hair follicles is rich in glycosaminoglycans and they seem to be involved in regulating hair growth. I have tried the new Marini Lash and it certainly works and I had no adverse side effects. The cost of Marini Lash is about $160, but we did turn up some better prices at

Another good find is Dermaquest's Dermalash Eyelash Growth Promoter Complex. It has restored my eyebrows to their former glory. Dermalash works for eyelashes as well, although you need to give it a good three weeks before you see any real results. I have no idea why Dermalash should be effective since the ingredients list consists mostly of botanicals that I have never been able to asscociate with any evidence that they promote hair growth. The most convincing of them is tussilago farfara, commonly called colts foot or coughwort. And there is apigenin, which stimulates the blood vessels (generally believed to be a good thing for encouraging hair growth). Anyway, this certainly works and it does no evil.

Keracyte-B is a reader nomination. I haven't used it myself but I have heard good reports and am tempted to give it try. Like Folligen, Keracyte-B is designed to treat hair loss and is marketed as a scalp conditioner. It has some very interesting ingredients. The active is elastatropin, the laboratory synthesized form of human tropoelastin, that is the natural precursor of the human elastin. It is supposed to have come out of research on wound healing at DARPA. Again, like Folligen, this product stimulates the hair follicle. The rest of the ingredients list reads like a good anti-wrinkle cream with the antioxidant, matrixyl 3000, sodium hyaluronate for moisture retention and selenium, which protects against UV damage.

I need to include Revitalash because the damn thing works. But I do so with some reservations. Although Revitalash has been reformulated several times in the last 12 months, the active has always been a prostaglandin analogue. The latest version, which has only just been launched, claims to be "100% safe" and Revitalash says there have been tests to prove it. However, it still contains a prostaglandin - read Copley's review of Revitalash.
