Are Eyelash Growth Serums Safe?

Ahoy There, Lash Lovers! Introducing Eyelash Growth Serums – Are They Safe?

Hey, hey, hey! If you’re anything like me, then you’ve always wanted longer, fuller lashes. And now, with the advent of eyelash growth serums, it seems like that dream is finally within reach. Before you jump onto the bandwagon, though, let’s talk safety. You don’t want to end up with spidery eyes or a nasty reaction, now do you?

Now, what exactly is an eyelash growth serum, you ask? Well, it’s a cosmetic product that claims to enhance the length, thickness, and darkness of your lashes. The serum is applied to the base of your lashes like eyeliner and left to work its magic. Sounds simple enough, right?

Before we dive into the world of eyelash growth serums, though, let’s address the elephant in the room – safety concerns. You don’t want to play fast and loose with your eyesight. So, let’s take a closer look at what you need to know before you get started.

Ingredients: The Good, the Bad, and the Ugly

Before diving into my personal experience using eyelash growth serum, I decided to do some research on the ingredients commonly found in these products. As it turns out, the world of eyelash health is more complex than I thought! Here are some of the most frequently listed ingredients in eyelash growth serums:

The Good: Several of the ingredients I came across in my research are known to promote eyelash growth and overall eyelash health. For example, biotin (a form of vitamin B) not only helps strengthen eyelash follicles, but it also protects the hair from damage. Another beneficial ingredient is panthenol (aka provitamin B5), which hydrates and nourishes both the lashes and the skin around them.

The Bad: Unfortunately, not all of the ingredients in eyelash growth serums are so benign. One such ingredient is prostaglandin analogs, which stimulate hair growth but can cause some less-than-ideal side effects. These can include redness, itching, and even changes in the color of your iris (the part of your eye that determines its color)! The FDA has even warned against using these types of ingredients.

The Ugly: It’s important to note that some ingredients don’t necessarily fall into “good” or “bad” categories, but they could still cause problems for some users. For instance, many eyelash growth serums contain fragrance, which can be irritating for those with sensitive skin. Similarly, some people may experience an allergic reaction to certain ingredients (such as phenoxyethanol or sodium benzoate), which can cause swelling, itching, or hives.

Overall, while some ingredients in eyelash growth serums seem to be quite beneficial, it’s crucial to be aware of the potential risks involved with others. As with any product, it’s important to research the ingredients and consult with a healthcare professional before starting a new regimen.

How to Apply Eyelash Growth Serum Like a Pro

Alright, let’s talk application. I know you’re excited to see results ASAP, but trust me, proper application is crucial. First things first, read the instructions carefully – this may sound obvious but you’ll be surprised how many people skip this step. Next, make sure your face is clean and free of any makeup or oils that may interfere with the serum. I like to apply mine at night after I’ve washed my face and brushed my teeth.

When applying the serum, use the applicator brush provided and start from the inner corner of your eye, applying the serum directly onto the lash line. You don’t need much – a little goes a long way. Avoid getting the serum in your eye, as this can cause irritation. If this happens, rinse your eye with water immediately. Once you’ve applied the serum to one eye, move onto the other, making sure to let the serum dry completely before touching your lashes or going to bed.

You may be tempted to ramp up your usage to speed up the growth process. However, over-applying can actually have the opposite effect and cause irritation. Stick to the recommended usage guidelines, which are usually once a day, and be patient – results can take several weeks to appear. Remember, slow and steady wins the race!


Okay, let’s be honest. Using an eyelash growth serum can come with some potential risks. First, there’s the risk of an allergic reaction. Some of the ingredients, like prostaglandins, can cause swelling or itching. It’s always a good idea to do a patch test before you apply it to all of your lashes. Just put a small amount on the inside of your elbow and wait for 24 hours. If there’s no redness or itching, you’re good to go!

Another risk is the possibility of discoloration of the skin or eyes. This usually happens if you accidentally get the serum in your eye, on your eyelid or the skin around your eyes. To avoid this, always make sure you’re carefully applying the serum with the brush that comes with it, and wipe away any excess with a clean tissue.

Last but not least, overuse of an eyelash growth serum can cause your lashes to become brittle and break off. That’s why it’s important to always follow the instructions on the packaging and not apply too much of the serum at once. Remember, more is not always better!

5. Benefits – What I Love About Eyelash Growth Serums

Before using an eyelash growth serum, I had always struggled with sparse and short lashes. But now, after seeing the benefits firsthand, I can’t imagine going back to my old lashes.

First of all, the biggest benefit of using an eyelash growth serum is obvious – longer, fuller lashes. They make my eyes look bigger and brighter and really help me to feel confident and beautiful.

Another benefit I love is how low-maintenance it is. Once I apply the serum, I can go about my day as usual without worrying about touch-ups or reapplication. It’s effortless and perfect for busy people like myself.

Another bonus is that it saves me money on other beauty products. I don’t need to use as much mascara because my lashes are naturally fuller and thicker. Plus, I don’t have to spend money on false lashes or lash extensions.

I also appreciate the convenience of using an eyelash growth serum. I can easily apply it at home instead of having to go to a salon or spa for expensive lash treatments. It’s a cost-effective and time-saving solution for achieving gorgeous lashes.

Overall, the benefits of using an eyelash growth serum are clear. It’s low-maintenance, cost-effective, and results in longer, fuller lashes that make me feel confident and beautiful.


Overall, after researching and evaluating the safety concerns, ingredients, application and use, and potential risks and benefits of using an eyelash growth serum, I have come to the conclusion that it can be a helpful product for those looking to enhance their eyelashes. However, it is important to be mindful of the potential risks and side effects that may come with using certain ingredients, as well as to follow instructions for application and frequency of use to minimize any negative effects. One of the main advantages of using an eyelash growth serum is the potential for longer, fuller lashes without the need for extensions or falsies. Additionally, many serums can also contribute to the overall health and strength of lashes, making them less prone to breakage and fall-out. That being said, not everyone may be a suitable candidate for using an eyelash growth serum, and it is important to weigh the potential risks against the benefits before making a decision. Those with sensitive skin or allergies may want to avoid certain ingredients, and anyone experiencing negative side effects should discontinue use right away. To summarize, while there are potential risks and side effects associated with using an eyelash growth serum, it can be a helpful and effective product when used appropriately. As with any cosmetic product, it is important to do your research, read reviews, and seek expert advice before deciding whether to incorporate an eyelash growth serum into your routine.
