A study published in the Journal of Optometry found that 44.3% of patients with eyelash loss due to alopecia areata experienced significant ophthalmological issues. This underscores the importance of effective eyelash growth treatments to enhance length, thickness, and density.
Among the available options, Lumigan (bimatoprost) has gained attention for its ability to stimulate eyelash growth. Originally developed to reduce intraocular pressure (IOP) in glaucoma patients, bimatoprost was later found to have an unexpected cosmetic benefit—promoting longer, fuller eyelashes. This discovery led to its off-label use as an alternative to traditional eyelash growth treatments.
In this article, we’ll explore how Lumigan enhances eyelash growth, its mechanism of action, clinical efficacy, potential side effects, and important safety considerations for those considering it as a cosmetic solution.
Key Takeaways
- Lumigan, which contains the active ingredient bimatoprost, is primarily used to treat glaucoma but has also been found to promote eyelash growth as a secondary effect.
- Clinical studies show that bimatoprost can significantly enhance eyelash length, thickness, and darkness over time, though Lumigan is not FDA-approved for cosmetic use.
- Users may experience side effects, including permanent pigmentation changes around the eyes and temporary ocular discomforts such as redness and itching.
- Compared to Latisse—an FDA-approved treatment specifically designed for eyelash growth—Lumigan contains a lower bimatoprost concentration and is primarily prescribed for reducing intraocular pressure (IOP) in glaucoma patients.

Mechanism of Eyelash Growth Stimulation
Lumigan’s generic name, bimatoprost, has been approved by the US Food and Drug Administration to reduce intraocular pressure (IOP) or high eye pressure in people with open-angle glaucoma or ocular hypertension. Interestingly, this solution has also been approved for cosmetic use, like Latisse, to grow eyelashes for people with inadequate lashes.
Bimatoprost enhances eyelash growth by imitating the action of natural prostaglandins, which regulate hair growth. It increases the percentage of eyelash follicles in the anagen of the growth phase, resulting in longer and thicker lashes. Additionally, bimatoprost boosts melanogenesis, making lashes darker.
Furthermore, the bimatoprost compound enlarges the dermal papilla and hair bulb, enhancing lash thickness and fullness. This serves as a common side effect of Lumigan in treated individuals.
Clinical Efficacy for Eyelash Enhancement
Clinical and preclinical studies have confirmed bimatoprost’s effectiveness in promoting eyelash growth. A five-month study demonstrated that bimatoprost 0.03% effectively enhances eyelashes in adults while maintaining an excellent safety profile. Participants in the study showed statistically significant increases in eyelash length, thickness, and darkness.
Clinical and preclinical studies confirm bimatoprost’s effectiveness in promoting eyelash growth. A five-month study found that bimatoprost 0.03% significantly increased eyelash length, thickness, and darkness in adults while maintaining an excellent safety profile.
Although Lumigan is not FDA-approved for eyelash growth, one of its common side effects is gradual eyelash enhancement. Over time, patients using Lumigan may notice longer, fuller, and darker lashes, likely due to its bimatoprost component stimulating hair follicles.
Despite limited clinical research specifically validating Lumigan’s use for eyelash enhancement, its active ingredient has proven efficacy in stimulating eyelash growth. While primarily indicated for lowering intraocular pressure (IOP), Lumigan remains a potential off-label option for cosmetic eyelash enhancement.
Safety Considerations and Potential Adverse Effects
Understanding the possible side effects of Lumigan allows both practitioners and patients to make informed treatment decisions, fostering trust, confidence, and better patient satisfaction.
Periorbital and Iris Pigmentation
- Permanent pigmentation changes may occur in the eyelid skin and eyelashes, often becoming noticeable months or even years after starting treatment.
- Additionally, increased iris pigmentation (darkening of the eye color) may develop over time and is often irreversible.
Ocular Side Effects
- Common side effects include eye redness, itching, dryness, irritation, and general discomfort.
- In rare cases, more serious reactions can occur, such as vision changes, eye swelling, or severe pain, requiring immediate medical attention.
Comparison to Latisse
Understanding their FDA-approved indications is essential for individuals comparing Lumigan vs. Latisse to determine which solution best addresses therapeutic or cosmetic concerns.
Lumigan
- Indication: Primarily prescribed to lower intraocular pressure (IOP) in glaucoma and ocular hypertension patients.
- Usage: Administered as eye drops, with the recommended dosage of one drop per affected eye, once daily in the evening.
Latisse (Bimatoprost 0.03%)
- Indication: Specifically designed to enhance eyelash growth, increasing length, thickness, and darkness.
- Usage: Applied once daily to the base of the upper eyelashes using a sterile applicator.
While both Lumigan and Latisse contain bimatoprost, Latisse is FDA-approved for eyelash enhancement and formulated for safe and effective long-term use. Lumigan may also promote lash growth as a side effect, but Latisse is the better option for those seeking targeted eyelash treatment.
Furthermore, both medications share similar safety profiles, with common side effects like eye redness, itching, and irritation. However, Lumigan may cause more pronounced periorbital pigmentation changes compared to Latisse.
Patient Counseling for Cosmetic Use
Individuals dealing with intraocular pressure (IOP) and seeking potential solutions for their hypotrichosis of eyelashes may opt for Lumigan. The secondary effect of eyelash growth may increase their satisfaction with the treatment, while Lumigan also targets IOP concerns. Lumigan’s efficacy may depend on the application.
- Ensure Clean Hands: Thoroughly cleansed hands before applying the medication can lessen infection or other risks.
- Tilt Head Back: Look up and gently pull down the lower eyelid to create a pocket.
- Apply Drop: Squeeze one drop into the pocket, ensuring the dropper does not touch the eye, fingers, or surface.
- Close Eyes: Gently close your eyes and press lightly on the inner corners to prevent the liquid from draining away.
- Blot Excess: Blot any excess liquid from the skin around the eye carefully.
Expectations and Monitoring
Seeking the guidance and expertise of licensed and experienced medical professionals can help patients set realistic expectations and minimize further complications throughout the Lumigan treatment. Having sufficient and necessary information about the solution can aid patients in understanding the benefits, risks, and importance of monitoring during the therapy.
- Eyelash Growth: Patients should expect gradual growth of longer, thicker, and darker eyelashes.
- Periorbital Pigmentation: They should know that potential darkening of the eyelid skin and increased iris pigmentation may be permanent. Lumigan eye color change may also occur when consistently used.
- Regular Monitoring: Schedule follow-up appointments with healthcare providers to monitor any adverse effects and ensure proper usage.
- Report Side Effects: Patients must inform their healthcare provider if they experience any side effects, such as eye irritation, redness, discomfort, or unusual symptoms, for prompt action and management.
Conclusion
While Lumigan is primarily prescribed for managing intraocular pressure (IOP), its eyelash-enhancing side effect has made it an intriguing option for cosmetic use. The active ingredient, bimatoprost, has been shown to increase eyelash length, thickness, and darkness, offering noticeable aesthetic benefits.
However, patients should be aware that Lumigan does not have FDA approval for eyelash growth. Patients must carefully weight the potential side effects and safety considerations. For those considering eyelash growth treatments, consulting a healthcare provider is essential to ensure safety, effectiveness, and the best treatment choice based on individual needs.
