Generally, there are little to no side effects to using Latisse. It is a fairly safe treatment for eyelash growth. However, some basic precautions should be taken, which we’ll explain below. Very few people - that is, less than 1-4% - report side effects from Latisse. However, even those unusual side effects are usually not permanent (such as blurry vision, eyelid irritation or discolouration of the eyelid skin). If you experience anything out of the norm, please contact us right away, so we can have a look and advise on next steps. Even if you are not sure if it was from the ingredients in Latisse, we encourage you to call us anyway. Also rare, but possible, is that each of your eyes may grow lashes of a different size, pigment, direction or thickness. This problem can be solved by stopping your usage of Latisse altogether. Your eyelashes will simply go back to the way they were, in due time. Since the administration of Latisse on your eyes will be done by you, at home, a lot of the safety implications will depend on your method of application. This is important. For example, removing contact lenses first, washing face and hands before application, using only the one-time sanitary swabs for each treatment and avoiding direct contact with the inner part of the eye are all necessary. Not following the product instructions precisely could lead to eye infections or other side effects, which you’ll want to avoid. Instructions will come in the package you’ll get from us, after you are prescribed Latisse by our on-staff physician at our Surrey medical spa. It’s ok if some of the Latisse solution gets in your eye, though you’ll want to avoid that happening in excess. Too much can darken the iris permanently, especially in light-coloured eyes.  Never dispense this product directly from the bottle into your eye or eyelids, or by using any other applicators except the ones provided in the package - especially not your fingers! Latisse should also not be used on lower eyelid lashes. Be sure to blot away any drips of the solution that fall around your eyes during application. Hair growth can happen in unintended places with this product! As mentioned above, please remember that using more Latisse for each treatment does not help your eyelashes grow any faster - even if you missed a day or two of treatments. The dosing of this product’s aesthetic usage is designed to help eyelashes grow, without affecting other parts of the eye. You’ll just be wasting product by applying more than necessary. Or worse, opening yourself up to the possibility of side-effects. If you have a tendency towards dry eyes, or wear contact lenses, you may need eye drops to keep your eyes hydrated while using Latisse. Also, be sure not to put in your contact lenses for about 15 minutes following the application of Latisse. Like any doctor-vendored medication, no one should share their Latisse prescription with anyone else - no matter how harmless it may seem. Some people are not eligible for Latisse. For this reason, a doctor’s advice and consultation is needed before using it. This is also why it is not sold over the counter. Those who are pregnant, or who have allergies to the ingredients in Latisse should not, of course, use this product. If you have vision problems, eye problems or eye injuries, you will also want to avoid Latisse until getting cleared by your doctor to use it. The same goes if you have any dermal (skin) issues around your eyes. If you have a bottle of Latisse solution you no longer want to use, you should still consult your city regulations, or a doctor, about how to dispose of it. We would advise that you don’t share it with another person, even that person has been given a prescription for the product as well. Please see more on our website.
