Latisse is a version of a glaucoma drug in eye drop form called Bimatroprost in use since FDA approval in 2001. During that period, eye doctors and their glaucoma patients noticed the hair growth side effect, with longer, lusher eyelashes appearing over time.

At the moment Latisse is licensed in America for eyelash growth. In the UK it is sold as Lumigan 0.3mg/ml but not licensed for cosmetic use.


According to studies, Latisse lengthens, thickens and darkens eyelashes. Like the hair on your head, eyelashes sprout, grow for a while and eventually fall out. Latisse both extends the growth phase and increases the number of hairs that sprout.


Latisse is applied by dabbing it on the upper lash line each night with the sterile applicators supplied. The drug spreads to your lower lash line automatically as you blink. It should never be applied in your eye or onto your lower lid. Before you apply Latisse, your face must be clean and your make up and contact lenses removed.

Always discard each applicator after one use. Reusing applicators, even just once the next evening, can cause serious problems, such as an eye infection or allergic reaction. It is important that Latisse is applied carefully as it may promote hair growth on other skin areas.

After 2 months of nightly use, you may begin to see results. After 3-4 months, your Doctor, may recommend a treatment schedule of every 2 days. If you stop using Latisse, your eyelashes will gradually return to their former state.

Study participants experienced these results after 16 weeks:

  • Eyelash length increased by 25%
  • Thickness and fullness increased by 106%
  • Eyelash darkness increased by 18%


According to clinical studies conducted with FDA approval, Latisse eyelash lengthener is safe for most people. However, you may not be a candidate for Latisse if you have certain eye problems (such as uveitis and conjunctivitis), risk of macular oedema, severe allergies or skin infections of the upper eyelids.

Pregnant women should not use it, and nursing women may wish to wait. Because the active ingredient in Latisse lowers intraocular pressure, if you are already using IOP lowering medications for ocular hypertension and/or glaucoma, you must tell your eye doctor before you try Latisse so he or she can monitor your eye pressure closely.

Most study participants had no problems if Latisse accidentally got into their eyes but a few did experience side effects that included dry eyes and eyelid skin darkening.

The side effects that occurred in the largest percentage of participants were eye redness (3.6%) and itchiness (also 3.6%). It was also reported that permanent brown pigmentation of the iris is a potential side effect, but it was not reported as occurring during the study when used for lenthening of the lashes.

When using the product for glaucoma ie dropping it into the eye, there is a small risk 1.9% of discolouration. This risk has been shown to be higher with generic products, but not with Bimatoprost.

Tell your doctor if you have any of the above side effects, as well as any vision problems, eye infections or allergic reactions. Also tell your doctor if you are planning to have any eye surgery.
