A lot of dermatology patients ask questions about a new eyelash product which promises longer, wider and even darker eyelashes. It's called Latisse. Latisse is a prescription medication, and it's made by Allergan, the same company that makes Botox Cosmetic. Previously, if a person wanted improved eyelashes, they had to use either artificial eyelashes or mascara. And now, with Latisse, in as little as six weeks, you can have longer, darker and wider eyelashes. The application of Latisse is easy. It comes with a bottle and a brush. A person should apply just one drop to the eyelid right next to the eyelashes every night. A person should only apply Latisse to the upper eyelid because it will transfer to the lower eyelid just by blinking. How does this product work? Very simply, the length of a person's eyelashes is determined by the amount of time that the hair follicle stays awake and grows. Normally, that's four months. With Latisse, it gets lengthened out to 6 or 7 months and, as a result, the eyelashes become longer and, as they become longer, they become darker and even wider. There are very few side effects with Latisse. Less than 4% of people who use it will get a little bit of irritation which goes away right away when you stop using Latisse. If a person is interested in Latisse, and if they would like to have longer, darker or wider eyelashes, then they should consult with their dermatologist for a prescription. In conclusion, Latisse is a good product, that does with it promises.
