Forget Mascara: Grow Your Own Longer Lashes

"Your eyelashes will experience real measurable growth." That's the claim made by Latisse, a new product from the makers of wrinkle-erasing/muscle-paralyzing Botox.

Pharmaceutical company Allergan got FDA approval in late 2008 for Latisse, whose active ingredient, bimatopost, has been used for several years in a product called Lumigan that treats glaucoma.

"The company began studying the potential of using a lower dose of topical bimatoprost to stimulate eyelash growth after Lumigan users developed unusually lush lashes," according to a Scientific American article from Dec. 29, 2008. "It's specifically being marketed as a once-a-day med to treat eyelash hypotrichosis, or lack of hair growth."

Of course, it's also of interest as a beauty-enhancing product. Latisse is expected to be available for prescription in March and cost $120 for a 30-day supply.

So there's real science behind Latisse, but is it worth it for the price?

"David E. I. Pyott, Allergan’s chief executive...suggested that many women would not blink at spending $120 for a one-month, three-milliliter supply of the drug," according to a New York Times article from Jan. 13, 2009. "He compared the cost of longer lashes to a daily cup of coffee.“If you think about it in terms of luxury, it’s four dollars a day,” he said. “We think this is fairly acceptable to a large segment of people even in these times.”"

Keep in mind, the lash-enhancement is not permanent.

"Because the drug works by keeping hairs in their growth phase -- the phase during which hairs become longer, thicker and darker -- lashes return to their normal, genetically determined length within a few months after discontinuing the drug," according to an ABC News article from Dec. 29, 2008.

Reported side effects
include itching and red eyes or darkening of the skin by the lash line, where the drug may come in contact with the skin. There's still more extensive testing to be done, though.

On a cool side note...the NYT article linked above quoted a fellow D.C. beauty blogger:

"Jennifer Nobriga, one of a pair of stay-at-home mothers behind the Web site beautyinreallife.blogspot.com, said she intends to stick with plain old mascara rather than splurge on the eyelash drug.

“It would not be at the top of my list,” said Ms. Nobriga of Woodbridge, Va. “I would rather spend the money on a good under-eye cream.”"

So what do I think?
It's an intriguing scientific development that I'm curious to learn more about. I think it has great potential, especially for people who've experienced hair loss or lack eyelashes. But it's not going to be joining my beauty arsenal any time soon.

As a young professional, I definitely don't have the cash to spend on Latisse! (Or a $4-a-day latte habit, though when you think of it that way it seems more reasonable.) Plus, I'm lucky to have naturally long, full lashes to begin with, and the suppleness of youth in my face, so I'm probably not the target audience for this product anyway. (I don't mean to toot my own horn too loudly, it just happens that I consider my eyes one of my stronger features.)

I definitely understand its appeal, though, and would probably try Latisse as long as I was confident in its safety. It's not injecting botulism into your face, so to me, it seems a tad less extreme than Botox.

But yeah, I'm going to keep unnecessary prescription treatments away from my eyes and stick to my Maybelline Full 'N Soft.


I'm curious what you all think!

Taking Care of Dry Hair

I got a great haircut just before the new year in New York. It's layered, falls slightly below my shoulders and has little side-swept bangs to boot. It's basically just three inches shorter than how I last had my hair, but losing the extra weight really gave my curls new life -- even now, six weeks later.

But an ongoing problem is how dry my hair and scalp are. I don't know if it's the shower water, or the weather, or products, or my diet, or damage from coloring treatments (though I haven't done that in a year). I rarely heat treatments on my hair but I use mousse or gel several times a week. Since I'm not a morning person I usually shower at night and throw my hair into a ponytail for work.

Oh, and split ends drive me CRAZY!

So I've been trying two inexpensive, out-of-shower treatments for the past few weeks: Jojoba oil and styling cream. I can't definitively prove their effectiveness since I don't have a scientific study or something behind me, but personally, I've found them beneficial. I plan to keep using them, since they certainly haven't visibly hurt my hair.

Jojoba oil is the liquid wax produced from the seed of the jojoba plant, which is native to parts of Arizona, southern California and northwestern Mexico. I chose it after reading that it is similar to sebum, the oily matter naturally present on human skin. It's purported to moisturize the scalp and help restore moisture and shine to hair. It doesn't have a strong scent and can be combined with essential oils.

I've been rubbing a nickle-sized drop into my hair occasionally before showering, particularly concentrating on my scalp and the ends of my hair. The oil I have is a combination of jojoba oil, castor oil, sunflower oil, lanolin, olive oil, BHA and fragrance. A little bit goes a long way, mind you. I picked mine up at a local beauty supply store.

For my styling cream, I've been using this Sedal (spanish-language Sunsilk) product I bought last year in Mexico to use in place of styling products while on vacation. This crema para peinar is intended to protect against the effects of summer, like heat and sun.


It seems like somewhere between a leave-in conditioner and styling product to me. Frankly, I bought it because the bottle was so cute! The main ingredients include cetearyl alcohol, cetrimonium chloride, glycerin and dimethiconol -- as far as I can see, a combination of emulsifying waxes, which contribute to locking in moisture by keeping water and oil from separating, and silicones, which feel soft to the touch.

So there's my science for the day. And since I've got jojoba oil in my hair I think it's time for the shower! Happy Valentine's day everyone!

My Lips Say 'Thank You'

I've been battling one of my arch nemeses lately -- raw, tight, uncomfortable lips. The temperature is still hovering around 70 degrees here in the Maryland-outskirts of D.C., yet my lips already feel like it's the middle of winter with the heat cranked up and poor ventilation.

Of course once your lips get dry like that, the problem can easily (and quickly) spiral out of hand. And my problem was that I had nary a Chapstick or bottle of Vaseline in sight. All my lip balms seemed to have vanished at exactly the moment I needed them! Plus, I was too lazy/indecisive/frugal to get something new...so I let things get progressively worse, till my lips really freaking hurt.

Then in the nick of time last night, I found my tin of Smith's Minted Rose Lip Balm.

You know it? If so, you probably love it.
"Created specially for Sephora, this cult-favorite, minty, multi-purpose lip balm soothes dry lips, calms and heals irritation, and soothes the sting of minor burns," the retailer's Web site says. "Try dabbing on dry elbows or knees to condition, and relieve dryness."

I haven't used it on my body much, but I'd believe it works. The ingredients are
: cotton seed oil, borax, aromol, and essential oils in a "special" petrolatum base. It's a lot more solid than regular petroleum jelly, but has a similar consistency when you get some on your fingertip. The nice smell and cool, minty-yet-subtle 'zing' of this stuff is a really nice change from your standard petroleum lippie though. The tin is adorable, and the product just has some fantastic quality about it I can't quite put my finger on. It feels really nice on, is pleasantly fragrant, restores my lips to a non-uncomfortable state, and it looks nice too...just the right amount of healthy shine.

In writing this post I did some research on borax, a compound that has some people concerned about its presence in cosmetics because it is also used in detergent and is toxic in high doses. This alarmed me a little bit too, so I turned to The Beauty Brains, a great site on which cosmetic chemists cut through advertising hype and look at the science behind products to give readers scientifically-accurate, unbiased information. (Packaged in an easy-to-read, entertaining way! Check the site out, for sure.)

In discussing what borax does in beeswax-based Lush lip balms, the Right Brain explains that it forms an emulsion, which is a stable mixture of two unblendable liquids, such as oil and water. (The Right Brain says about Lush: "Borax-beeswax emulsions are unusual - they’re “water in oil” emulsions so the water drops are dispersed in the oil. That type of emulsion tends to be more water proof which is good for a lip balm.") Smith's uses petrolatum and not beeswax, however, it still seems logical that like in the Lush product, Smith's salve uses borax as an emulsifier instead of turning to a multitude of other chemicals.

"And a final note: if you do any kind of web search on Borax you’ll find that it can also be used as an insecticide, but don’t worry about that," Right Brain notes at the end of the post. "It’s only toxic to humans at very high levels - in fact it has the same toxicity profile as common table salt. (Hey, even water can be toxic if you drown in the stuff!) So a little bit in your lip balm is perfectly fine."

So I'm willing to believe that borax is safe in this use. I haven't tested it myself, but when you consider all the carcinogens and potentially harmful substances we all encounter everyday...plus the fact that, as the Brains point out, a lot of things are toxic in high doses but safe in smaller quantities.
