Lash Serums: Do They Work & What To Watch Out For
Listen On
As an ophthalmologist and mom of three, I'm no stranger to the obsession many women have with achieving long, lush lashes. In fact, I'll admit I'm one of them! That's why I'm so passionate about educating my patients and followers on the science behind lash growth and the potential risks of using certain lash serums.
The Science of Lash Growth
Our lashes, like the hair on our heads, follow a natural growth cycle with three main phases: anagen (growth), catagen (transition), and telogen (resting). Only about 40% of our upper lashes are in the growth phase at any given time, which is why lash growth can seem so slow.
This is where certain lash serums containing prostaglandin analogs come into play. These ingredients, which are also used in some glaucoma medications, have been found to extend the anagen or growth phase, leading to longer, thicker lashes.
The Risks of Prostaglandin Analogs
However, as an ophthalmologist, I can't stress enough the importance of being cautious with these types of lash serums. Prostaglandin analogs, even in their synthetic forms, can come with some serious side effects, especially for those of us with lighter colored eyes.
I've seen patients experience permanent changes in iris color, as well as issues like redness, irritation, and even unwanted hair growth. And the risks don't stop there - some lash serums containing these ingredients have also been linked to eyelid pigmentation and a concerning condition called eyelid atrophy, where the fat around the eyes thins out, leading to a hollowed-out, aged appearance.
Safer Alternatives
The good news is there are plenty of alternative lash serum ingredients that can nourish and strengthen your lashes without the same risks. Look for peptides, biotin, hyaluronic acid, and panthenol - these ingredients have been shown to condition and protect lashes, helping to reduce breakage and make them appear fuller, even if they don't necessarily stimulate longer growth.
Consult Your Eye Doctor
And if you're still set on using a prostaglandin-based serum like Latisse, please, please, please consult with your eye doctor first. They can help you weigh the benefits and risks and monitor you for any potential side effects.
Conclusion
At the end of the day, our eyes are delicate, and they deserve the best care possible. As an ophthalmologist, my mission is to help you make informed decisions about eye health and vision care, and that includes being cautious with the lash serums you use. So, do your research, talk to your doctor, and choose wisely - your eyes will thank you!
