How does LATISSE® work?

LATISSE® is believed to affect the growth (anagen) phase of the eyelash hair cycle in two ways: first, it increases the length of this phase; and second, it increases the number of hairs in this growth phase. The exact way it works is unknown.

Is LATISSE® effective?

The LATISSE® clinical study was conducted at 16 sites across the country and included 278 participants, featuring women and men of various ages (22 to 78), backgrounds and eye colors. Throughout the course of the 16-week treatments, each participant was photographed and evaluated at 4-week intervals (week 0 to week 16) for differences in their overall lash prominence, including elements of length, thickness and fullness. At 16 weeks, the results showed that LATISSE® was effective for 78% of those participating, versus 18% for the vehicle group. Vehicle is the same as LATISSE®, without its active ingredient.

How do I apply LATISSE®?

LATISSE® solution is a once-a-day treatment you apply yourself each evening to the base of the upper eyelashes. DO NOT APPLY in your eye or to the lower lid, because excess hair growth outside the treatment area may occur. See the full instructions in How to Apply, and apply as instructed by your doctor.

What are the possible side effects of LATISSE®?

The most common side effects after using LATISSE® solution are an itching sensation in the eyes and/or eye redness. This was reported in approximately 4% of patients. LATISSE® solution may cause other less common side effects which typically occur on the skin close to where LATISSE® is applied, or in the eyes. These include skin darkening, eye irritation, dryness of the eyes, and redness of the eyelids.

If you develop a new ocular condition (e.g., trauma or infection), experience a sudden decrease in visual acuity, have ocular surgery, or develop any ocular reactions, particularly conjunctivitis and eyelid reactions, you should immediately seek your physician's advice concerning the continued use of LATISSE® solution.
