Bimatoprost Serum Side Effects on Eyelash Growth

by | Aug 12, 2023 | Bimatoprost | 0 comments

While Bimatoprost’s side effects are permanent but can fade away with time, this blog will help you learn about the side effects of Bimatoprost and how to cope with them.    

Rarely the same medicinal preparation is used for both medicinal and cosmetic purposes. But Bimatoprost is capable enough to perform double duty. In addition to treating ocular hypertension and glaucoma, it is extremely beneficial in promoting eyelash growth.  

It works effectively in both cases, but is it safe? Can it bring lasting changes to your eyes? The answer to both these questions is yes. It is important to follow the usage instructions carefully to reduce the risk of side effects. If you use it properly, you are exposed to the eye to only 5% of the ophthalmic preparation compared to the eye drop method utilized for treating glaucoma.  

How does Bimatoprost work to grow eyelashes?  

Before application, rinse your hands and face, removing any makeup. The eyelash growth solution is used once nightly and is applied to the roots of the upper lashes with the help of a single-use applicator. It functions by creating more hair follicles during the hair growth cycle. The FDA approves Bimatoprost 0.03% ophthalmic solution on the upper lash line. It may spread to the lower lash line as you blink, but the primary effect of the eyelash serum will be on the upper eyelashes only. You don’t need to get concerned if the medication gets into your eye as it is utilized for glaucoma treatment and is unlikely to cause damage.  

Results usually appear within two months. If you stop using the eyelash growth solution, your lashes will gradually return to their previous state.

Safe options for most users

The FDA approved Bimatoprost 0.03% solution, which is considered safe for adults. Because Bimatoprost is the same active component, and if you are dealing with ocular hypertension and glaucoma, you may already be treated with this medicine. Using this pharmaceutical agent may cause side effects in some people.

Side effects of Bimatoprost   

Most patients do not have any side effects. However, there have been reports of the following:

  • Change in eye colour: usually occurs within eight months of using the eye drops. This colour change can be permanent and may be more common if you use it only in one eye.  
  • Eyelid skin darkening can sometimes be permanent
  • Red, itchy eyelids, dryness, or feeling that something in your eye.
  • Hair growth in other areas that Bimatoprost 0.03% solution touches, such as around the eyes.  

Serious side effects or allergic reaction

 Do not use more Bimatoprost 0.03% solution and call your health care provider if you:

  • Experience shortness of breath
  • Are you having asthma and your breathing worse
  • Become dizzy

Rarely is it possible to have a serious allergic reaction to Bimatoprost. The symptoms of an allergic reaction include:

  • Your lips, throat, and mouth suddenly become swollen
  • Your breathing is faster, or you are struggling to breathe
  • Your throat feels tight, or it becomes tough for you to swallow
  • Your skin, lips, or tongue turns blue, pale or grey
  • You suddenly become drowsy, dizzy or confused

A serious allergic reaction can cause all these signs and may need immediate medical attention. These are not all the side effects of Bimatoprost. You can report any suspected side effects to your healthcare provider.    

Eyelash serum and contacts 

If you wear contacts and wish to try Careprost, you should know that the FDA warns that your contact lenses can absorb the product, which can change the colour of your contacts. Ensure you remove your contact lenses before applying the solution and wait fifteen minutes before wearing them back.  

Coping with side effects 

Irritation should resolve once your body adjusts to Bimatoprost, but speak to your healthcare provider if you are worried about this. A cold water compress on the closed eye can help relieve itchy eyelids or eye pain. If the lash growth serum is irritating your eyes, releasing water so much that you think of stopping the application, speak to a health care specialist. They may recommend something to eliminate the problem.   

Change in the colour of the iris or darkened skin around the eye is obvious, and one can do nothing about it. Discuss with your healthcare provider if this bothers you.  


Bimatoprost 0.03% is approved for increasing eyelash length, thickness, and darkness in patients with hypotrichosis of the eyelashes. For eyelash enhancement, one drop of bimatoprost ophthalmic solution is placed on the applicator and applied on the base of the eyelashes once nightly. The eyelash growth solution is safe when applied on eyelashes with minimum side effects.

Some users can experience eyelid itching, dry eyes, bloodshot, and eyelid darkening. Eye and eyelid swelling, as well as some serious allergies, can also occur, according to the US Food and drug administration (FDA). More significant adverse effects include increased eyelash growth in the corners of the eyes or other areas of the skin if the eyelash growth solution touches them. Immediately inform your ophthalmologist about eye pain, infection, or vision changes.
