What is latisse?
Latisse (bimatoprost 0.03%) is a prescription eyelash growth treatment, originally developed as a glaucoma medication. A side effect — significant eyelash growth, thickening, and darkening — became the basis for its cosmetic use.
Applied to the upper lash line nightly, Latisse causes lashes to grow longer, fuller, and darker over 8–16 weeks. Results require continued use; stopping leads to gradual return to baseline lashes over several months.
The medication is generally safe and well-tolerated. Main side effects: occasional eyelid darkening (reversible), eye redness, itching, and rarely permanent darkening of the iris (mostly seen with glaucoma use of the same drug in the eye itself).
Do I have latisse? Common signs
If most of these describe what you're experiencing, telehealth is a reasonable next step:
What causes it
Variable. Age-related thinning, alopecia, chemotherapy-induced lash loss, eyelash extensions damage, thyroid disease, eyelash mite infestation. Sometimes simply genetic — lashes vary in length and density between individuals.
Is it contagious?
No (lash thinning isn't).
Apply just to the upper lash line — touching the lower lid wastes product and risks unwanted hair growth.
Can it be treated online?
Latisse evaluation is well-suited to telehealth. A clinician reviews your eye health history, current eye conditions, medications (especially glaucoma medications), and current state of lashes. Most healthy adults are good candidates. Prescription sent to pharmacy.
Not a good candidate via telehealth: active eye infections or inflammation, glaucoma on prostaglandin treatment already, recent eye surgery, history of iris pigmentation concerns.
How latisse is treated
Latisse (bimatoprost 0.03% solution): applied nightly to the upper lash line only using the supplied disposable applicators. One drop per applicator, swept along the upper lash line at the base.
Apply to upper lash line only — extra product on lower lid wastes it and risks unwanted hair growth on cheeks.
Remove contact lenses before applying; can reinsert 15 minutes after.
Results timeline: visible changes typically begin around week 4, peak around week 16. Maintenance can sometimes be reduced to every other day after peak.
Self-care while you wait
- Apply nightly to clean dry skin at the upper lash line
- Use only the supplied applicators — fresh one for each eye
- Don't apply to lower lid
- Remove eye makeup and contacts before application
- Be patient — visible changes take 4–8 weeks, peak at 16
- Discontinue if eyes become significantly red, itchy, or irritated
- Tell your eye doctor you're using it
- For maintenance after results, some can reduce to 3–4 times weekly
How long does it last?
Lash growth is visible at 4–8 weeks, peaks around 16 weeks. Treatment is continuous — stopping leads to gradual return to baseline lashes over several months. Long-term use is generally safe.
Frequently asked questions
Will my eyes turn brown?
True iris color change is very rare with cosmetic Latisse use. The phenomenon was seen mainly with intraocular use for glaucoma (drops in the eye itself, much higher exposure). Eyelid darkening is more common but reversible after stopping.
Can I use it on my eyebrows?
Off-label use for eyebrows is common and generally effective. Apply with a clean brush to the brow area nightly.
Will my lashes fall out if I stop?
Lashes return to their baseline state over a few months after stopping. You don't lose extra lashes — you just stop maintaining the improvement.
Can I wear lash extensions while using Latisse?
Yes, but apply Latisse before extensions are placed, and use carefully so as not to disturb adhesive. Some prefer cycling — extensions for a season, then a Latisse course.
Is there a generic?
Yes — generic bimatoprost 0.03% solution is significantly cheaper. The generic ophthalmic solution (without the applicator system) can be used with a fine brush; some patients use Lumigan (the same medication branded for glaucoma) similarly. Discuss with your clinician.
