Latisse: Benefits, Side Effects & More

Latisse is the first prescription treatment for inadequate or scarce eyelashes. It aids in growing eyelashes to be darker, fuller, and longer.  

Latisse’s side effects may include brown darkening of the colored part of the eye, which is likely to remain permanent.  It may also cause eyelid skin darkening (though it may be reversible), hair growth outside of the treatment area, and itchy and red eyes.

What Is Latisse?

Latisse is the first FDA-approved treatment to help those that have inadequate eyelashes (hypotrichosis).  

The Latisse solution is applied topically on the base of the upper eyelashes once every night.  Some see results in as little as 4 weeks, but it will take up to 16 weeks to achieve full growth.

How Does Latisse Work?

According to Latisse’s website, lash growth is possible due to the active ingredient known as bimatoprost.  Bimatoprost is a synthetic prostamide analog (a lab-created, active, lipid-like substance) that is approved for the treatment of eyelash growth.  

Latisse states that the exact process by which bimatoprost works is unknown, but the company has a theory. Latisse is believed to influence the growth of the eyelash hair cycle in these ways.

  1.  It lengthens the growth cycle phase.
  2.  It boosts the number of hairs in this phase.

Side Effects 

Side effects of Latisse are possible and include the following:

  • Brown darkening of the colored part of the eye, which is likely to be permanent
  • Eyelid skin darkening, which may be reversible
  • Hair growth outside of treatment area
  • Itchy and red eyes

The most frequently experienced side effects are itchy and irritated eyes. According to Latisse, this was experienced by 4 percent of participants in their clinical trial.

If you develop any side effects, see your doctor as soon as possible. 

Latisse Risks

Latisse use comes with some potential risks. 

  • Effects on intraocular pressure: Bimatoprost is known to lower intraocular pressure (fluid pressure of the eye) when directly applied to the eyes of patients with elevated intraocular pressure. However, clinical trials showed that patients with and without elevated intraocular pressure actually had lower intraocular pressure when using Latisse.  But these findings were on a small level and not cause for concern.
  • Intraocular inflammation: Latisse should be used with caution by users with active intraocular inflammation, as it could potentially make the condition worse.
  • Macular edema: Macular edema (the accumulation of fluid in the area in the center of the retina) has been reported when using treatments with bimatoprost. People who have aphakia (missing a lens in the eye), who have a torn posterior lens capsule, and who already have or are at risk for macular edema should be wary.

Who Is a Candidate for Latisse?

Candidates for Latisse should be at least 18 years old. They may have insufficient eyelashes due to the following:

  • Hypotrichosis (a rare condition that affects hair growth)
  • Genetic conditions that cause thinner or paler lashes
  • Conditions that affect the eyes, eyelids, and eyelashes, which will eventually lead to hair loss
  • Injuries that have caused hair loss
  • Radiation or chemotherapy

Who Is Not a Candidate?

People who should not use Latisse if they meet any of the following criteria:

  • Under 18 years old
  • Allergic to any ingredient in Latisse
  • Pregnant or breastfeeding
  • Do not have a prescription for Latisse

If you have any pre-existing eye conditions, consult an eye doctor before using Latisse.

Considerations When Using Latisse

  • Latisse can be used by people who wear contact lenses, but contacts must be removed before applying Latisse. Since Latisse contains benzalkonium chloride, it is important to note that discoloration of soft contacts can occur.  
  • Be sure that the Latisse bottle is fully intact before using it. 
  • The treatment should be used exactly as instructed and only by a person with a valid prescription for it.  
  • The bottle tip should not be in contact with any foreign surface, or it increases the risk of bacterial infection. 
  • The single-use applicator should only be used on one eye and then discarded. A sterile applicator should be used each time.
