This post has been UPDATED. For the June 2009 roundup click here.

I posted a round-up of eyelash growth products, summarizing whether they worked and were safe. Since then, products have come and gone, new information has come to light and I've tested a few more. So here is an updated eyelash enhancer round-up.

Jan Marini Age Intervention Eyelash Conditioner. It certainly worked; my eyelashes were growing like weeds after three weeks of use. However, it was yanked off the market at the beginning of January, although you can still find it for sale here and there. It contained prostaglandin (an analogue to be precise), a powerful drug used to treat glaucoma. The positive side effect is that it makes your eyelashes darker, thicker and longer. Bad side effects can include burning/itching and change of eye color. I stopped using it as soon as I found out about prostaglandin.

Jan Marini's Marini Lash. Jan Marini has a new lash product without prostaglandin. I've just posted a review after trying it for three weeks. It works and it's safe.

Dermaquest's Dermalash. This also worked for me (see review). Longer lashes and some new growth. It has done a very good job of filling in my eyebrows as well. No glaucoma drugs (it uses amino acids and vitamin B) and I had no allergic reactions to it.

MD Lash Factor. This product reportedly works. It too contains prostaglandin. See Jan Marini, above.

Revitalash. Some reviewers report a burning sensation when using Revitalash. If it doesn't bother you, it does seem to work. Revitalash used to be based on an ingredient called bitamoprost (this is what prompted the FDA recall of Jan Marini's original product). Revitalash reformulated the product to use prostaglandin. The newest version is claimed to be 100% safe.

Keracyte-B. Keracyte-B is a scalp conditioner that uses elastatropin, a synthetic form of elastin. This is aimed at stimulating the hair follicle. There are some anti-aging ingredients, such as matrixyl 3000,  mixed in too. It does not contain prostaglandin. I haven't tried it, but have heard that it works.

Renew Eyelash Revitalizer. For some reason, persons under 18 can't use Renew without a doctor's prescription. I haven't used it and haven't come across anyone who has. Renew doesn't contain prostaglandin. It really seems as though it is a hair regrowth product that is being marketed for eyelashes. The main ingredients are: tripeptide-1, a kind of protein used to prevent the breakdown of collagen, and biotin, a B vitamin used in hair regeneration products.

RefectoCil Longlash. This has the benefit of being cheap (about $20) and RefectoCil does not contain prostoglandin. I can't imagine that it works since it is just a concoction of plant extracts. If your esthetician tries to get you to try it, bear in mind that the maker markets it to salons by saying they can expect a 300% profit margin when they sell RefectoCil.

Lilash. This was developed by a doctor in Scotsdale. Thanks to a reader's sleuthing skills, we now know that the ingredients for Lilash contain a prostaglandin analogue. I've had reports of allergic reactions.

Talika. The best thing I can say about Talika is that it comes with a nice origination myth (a young French doctor treating World War II casualties in Paris in 1948 finds out that her potion of plant extracts heals wounds and makes eyelashes grow). I have read a review saying it doesn't work. Quelle surprise.

Mavala. This product is applied like mascara (most of them are applied like an eye-liner). Anyway, it doesn't work.

FNS Nutrilash. I tried this and it didn't work after four weeks. Perfectly safe though.

Lumilash. Reportedly in the works by Allergan. Not yet on the market and Allergan has just applied for FDA approval.

Peter Roth Thomas Lashes To Die For. Contains a prostaglandin analogue.

Intuit Beauty Enormous Lash. This one also contains a prostaglandin analogue, and this is how it appears in the ingredients list: 17 phenyl-13, 14-dihydoro trinor PGF 2 (Alpha). Not as "revolutionary" as Intuit claims.

Skin Research Laboratories Neulash. This contains prostaglandin analogue.

SD Lash. Made by Phoenix Medical, this has natural ingredients with the active being hexapeptide 11 (derived from yeast). Some readers have reported good results.

Skin Biology's Folligen. A copper peptide cream that is primarily designed for hair growth. It works by strengthening the hair follicles. I have had really good results on brows and lashes.

B Kamins Chemist Lash Fortifier. Natural ingredients of the kind found in hair growth products.
