Key takeaways
- Latisse is a prescription drug you apply at home, not a treatment a med spa performs.
- Apply it once nightly to the upper lash line only; extra applications do not increase growth.
- Iris darkening is likely to be permanent; the lash growth is not.
- FDA-approved generic bimatoprost 0.03% exists; over-the-counter lash serums are not Latisse.
What is Latisse and how does it work?
Latisse (bimatoprost ophthalmic solution 0.03%, Allergan/AbbVie) is a prescription drug.
The FDA approved it on December 24, 2008, under NDA 022369, to treat hypotrichosis of the eyelashes — inadequate or not enough lashes — by increasing their growth, including length, thickness and darkness.
The carton is marked "Rx only": it requires a prescription from a licensed prescriber, and it is not an over-the-counter lash serum.
The label spells out exactly how it is used.
One drop goes on a new, sterile, single-use applicator, which is brushed along the skin of the upper eyelid margin at the base of the lashes, with a fresh applicator for the other eye.
The label says not to apply it to the lower lash line, and it says extra applications will not increase the growth of eyelashes.
What the label does not describe is an in-clinic procedure, because there isn't one: Latisse is self-applied at home, once a night.
The med spa's role is the prescription — not a "lash treatment" performed on you.
What does Latisse treat, and who is a good candidate (and who isn't)?
The indication on the label is hypotrichosis of the eyelashes — inadequate or not enough lashes.
That is what the FDA approved the drug for, and it is the use this page describes.
Whether your own lashes qualify is a judgment for the licensed prescriber who examines you, not something a page can decide.
The label also flags several situations a prescriber will want to know about.
People using prostaglandin drops to lower their eye pressure (intraocular pressure, or IOP) are told to consult their doctor and be monitored, because Latisse may reduce the effect of those drops.
The label counsels caution with active eye inflammation and with risk factors for macular edema.
Contact lens wearers should remove their lenses before applying it and can re-insert them 15 minutes later.
The contraindication the label lists is hypersensitivity to bimatoprost or to any of the product's other ingredients.
One gap to name plainly: the sources behind this page don't cover use in pregnancy or while breastfeeding, so that is a question to put to the prescriber directly rather than assume.
How much does Latisse cost at a med spa?
We can't give you a verified price.
Allergan does not publish a list price on the drug's label, and RealSelf and GoodRx were not used or were blocked in our research, so any dollar figure you may see quoted online is unverified as far as this page is concerned.
The price you are quoted at a practice is that practice's own price.
What we can describe is what you are buying.
Latisse comes in two sizes in the US: 3 mL of solution (in a 5 mL bottle) with 70 applicators, and 5 mL with 140 applicators.
Used as directed — one applicator per eye, each night — the 70-applicator kit holds about 35 nights' worth and the 140-applicator kit about 70.
That is arithmetic from the label's contents, not a labeled statement of how long a bottle lasts.
Latisse US kit sizes
| Kit | Solution | Bottle | Applicators |
|---|---|---|---|
| Smaller kit | 3 mL | 5 mL bottle | 70 |
| Larger kit | 5 mL | 5 mL bottle | 140 |
When you compare quotes, you are comparing three things: brand versus generic, kit size, and where the prescription is filled — a practice may dispense on site or send the prescription to a pharmacy, and who may dispense at a med spa is governed by state law (more below).
One concrete figure does exist in the program's own terms: Allē, the rewards program that lists Latisse among its eligible products, publishes base earn rates of 50 to 150 points per Latisse kit (Allē's own published rates, read October 2026).
Points are not dollars — ask the practice what the kit costs before you commit.

What results can you expect, how many sessions, and how long do they last?
How many sessions: none.
Latisse is a nightly home routine, not an in-clinic treatment, and the label says extra applications will not increase growth — so "more" is not a way to speed it up.
How fast it works is something the label describes as gradual: it is not significant in most patients until 2 months.
The label's pivotal trial measured the primary endpoint at week 16, where 78% of Latisse users had at least a 1-grade improvement in eyelash prominence, compared with 18% on vehicle (the trial's control solution).
The same trial measured how much the lashes changed by week 16: length increased 25% and fullness/thickness 106% from baseline, against 2% and 12% with vehicle, and lashes darkened 18%.
Those are group averages from one trial — a description of what was measured, not a forecast for your lashes.
How long they last is the least glamorous line in the label: the effect is not permanent.
When treatment stops, eyelash growth is expected to return to its pre-treatment level.
The label tells prescribers to counsel patients of exactly that — the effect can be expected to gradually return to the original level once you stop.
Does Latisse hurt, and what is the downtime?
There is no procedure, so there is no recovery period of the kind a laser, a peel or an injection has.
No procedure is done to you at the med spa; the daily routine is a drop on an applicator, brushed along the upper lash line, and the label describes no in-office session to book or recover from.
What the label does record is where discomfort shows up in its side-effect data: in the 278-patient trial, the most frequently reported reactions were eye itching, eye redness, skin darkening, eye irritation, dry eye symptoms and eyelid redness, each in fewer than 4% of patients.
Pain is not a listed measurement in the trial data our research pulled, so we won't guess at what application feels like.
Two technique points double as comfort and safety measures.
Use a new sterile applicator for each eye, and keep the solution off the lower lash line, which the label says not to apply it to.
Contact lens wearers remove their lenses before applying and re-insert them 15 minutes later.
If your eye hurts or looks worse after you start, that is a conversation for the prescriber, not something to push through.
What are the side effects and risks?
In the 278-patient, 4-month trial, the most frequently reported side effects were eye itching, eye redness (conjunctival hyperemia), skin darkening, eye irritation, dry eye symptoms and eyelid redness — each in fewer than 4% of patients.
The label's warning section adds a set of slower-moving risks the trial numbers don't capture:
- Iris pigmentation: Latisse can increase brown pigmentation of the iris, which the label says is likely to be permanent and may not be noticeable for months to years.
- Eyelid skin darkening, which has been reported to be reversible in most patients after stopping.
- Unwanted hair growth where the solution repeatedly touches the skin — one reason the label is strict about where the applicator goes.
- A possible reduced effect of glaucoma prostaglandin drops; users of IOP-lowering prostaglandins should consult their doctor and be monitored.
- Caution with active eye inflammation and with risk factors for macular edema.
- Contact lenses out before applying, re-inserted 15 minutes later.
That list is the label's, not a forecast for your eyes.
A prescriber who examines you can put your own eye history — glaucoma drops, contact lens wear, eye inflammation or macular edema risk factors — against it before you start.
Latisse can increase brown pigmentation of the iris, which the label says is likely to be permanent and may not be noticeable for months to years. Postmarketing reports also describe periorbital fat atrophy and skin tightness causing a deepened eyelid sulcus and eyelid drooping (ptosis); the label says the frequency cannot be reliably estimated.
Latisse vs the alternatives: which is right for you?
The nearest alternative is the generic version of the same drug.
FDA-approved generic bimatoprost ophthalmic solution 0.03% exists for the same eyelash hypotrichosis indication — the examples in our research are Sandoz (ANDA 202719) and Alembic (ANDA 210515), and those generics are also prescription-only.
Our sources hold no head-to-head trial between those generics and Latisse, so there is no evidence-based ranking here; brand versus generic is a prescriber-and-pharmacy question.
One don't belongs next to that: glaucoma eye drops that contain bimatoprost are a different product, and nothing on this page covers using them on the lashes.
Against over-the-counter lash serums, the honest comparison is short: they are not Latisse.
Latisse is the prescription drug the FDA approved to treat eyelash hypotrichosis, with the trial data and warning section above; an OTC serum is a different product that does not carry that drug's FDA label, and this guide does not evaluate those products' marketing claims.
If you are weighing them against each other, that weighing — like every "which is right for me" question on this page — belongs with the licensed prescriber who examines your eyes.

- Prescription-only
- Generics carry the same hypotrichosis indication
Over-the-counter lash serums
- Not Latisse
- Do not carry that drug's FDA label
- Marketing claims not evaluated in this guide
Who should perform Latisse, and how do you find a med spa near you?
Start with the reframe: nobody "performs" Latisse.
It is a prescription drug you take home and apply nightly, so what you are choosing is not an injector's hands but a prescribing workflow — a licensed prescriber who examines you, writes the prescription, and explains the label's application and warning sections.
Who may prescribe and dispense a prescription drug inside a med spa is governed by state law, and the drug label doesn't answer it — so ask the med spa directly who will write your prescription and what that person's license is.
For screening the practice itself, our how to choose a med spa checklist covers credentials, supervision and pricing; and if you are still deciding what kind of setting this even is, what a med spa is covers who works there and how it differs from a day spa.
- Ask who will write the prescription, and check that person's license.
- Ask whether you are being prescribed brand Latisse or generic bimatoprost 0.03%.
- Ask which kit size you are paying for — 3 mL with 70 applicators, or 5 mL with 140.
- Ask the kit's price before you commit; we could not verify one.
- Make sure someone walks you through the once-nightly application, including the lower-lash-line "don't".
Frequently asked questions
Do you need a prescription for Latisse?
Yes.
The carton is marked "Rx only", so Latisse requires a prescription from a licensed prescriber — it is not an over-the-counter lash serum, and a product sold without a prescription is not Latisse.
Who may prescribe and dispense a prescription drug inside a med spa is governed by state law, so ask the practice directly who will write yours.
Is there a generic version of Latisse?
Yes.
FDA-approved generic bimatoprost ophthalmic solution 0.03% exists for the same eyelash hypotrichosis indication — our research's examples are Sandoz (ANDA 202719) and Alembic (ANDA 210515), and those generics are also prescription-only.
We found no head-to-head trial against the brand in our sources, so which one to fill is a question for your prescriber and pharmacy.
What happens if you stop using Latisse?
Eyelash growth is expected to return to its pre-treatment level.
The label tells prescribers to counsel patients that the effect is not permanent and can be expected to gradually return to the original level once treatment stops.
That is the flip side of how the drug works: it grows lashes while you use it, and there is no permanent change to keep afterwards.
Can Latisse change your eye color?
The label warns that Latisse can increase brown pigmentation of the iris, which is likely to be permanent and may not be noticeable for months to years.
It can also darken the skin of the eyelids, which has been reported as reversible in most patients after stopping.
In the 278-patient trial, skin darkening was among the most frequently reported reactions, each in fewer than 4% of patients.
Put questions about your own eyes to an eye-care prescriber.
How long does one Latisse kit last?
Latisse comes in two sizes in the US: 3 mL of solution (in a 5 mL bottle) with 70 applicators, and 5 mL with 140 applicators.
Used as directed — one applicator per eye, each night — the smaller kit holds about 35 nights' worth and the larger about 70.
That is arithmetic from the label's contents, not a shelf-life statement; your own refill schedule is a prescriber question.
