Bold, stunning, and full eyelashes are a dream goal for many of us. We cheat with falsies, deal with lash extensions, and squeeze lash curlers.

And an often-overlooked beauty tool you can use that will help you with this is lash serum. 

How, exactly, do you apply eyelash serum? And does it work?

In this article, we’ll show you how to apply lash serum properly, so that you can get the best results from your serum.


Eyelash Serum for Lash Growth

Revitalash Serum

Lash serum is a very popular beauty product that is promoted to help your natural lashes to grow even thicker and more luscious. 

There is one main brand of lash serum: Latisse, which is a prescription eyelash growth serum that does have solid evidence of success. The downside, of course, is that you have to go to a doctor to get it.

Many other serums exist on the market, including some like Revitalash (which I looked at here) that attempt to clone the active ingredient of Latisse without requiring a prescription.

And other serums contain ingredients that are known to stimulate the hair follicles, which in turn promote lash hair growth. Some of the most common ingredients include vitamin B7 (also known as biotin), panthenol, hyaluronic acid, and castor oil. 

All of these ingredients also work to moisturize and hydrate your natural lashes, which prevents them from breaking. In addition, using lash growth serum can help to extend the growth cycle of your natural lashes.

Many beauty enthusiasts turn to using lash serum after having their eyelash extensions removed, which can sometimes leave your natural lashes brittle and breaking from the constant extra weight and gluing.

Does Eyelash Serum Work?

Latisse is highly likely to work, though the over-the-counter growth serums will be much more hit-or-miss.

Therefore, you should definitely learn how to apply lash serum in the right way.

So, let’s take a look at what you need to do.

How To Apply Lash Serum in 6 Easy Steps

Revitalash Serum Before and After

Here are 5 tips on how to apply lash serum with the risk of irritation of the eye. There are just four simple steps that you need to take in order to apply your lash serum for the best effect. These steps are:

1. Lense Cleanse

If you wear contact lenses, remove them before you start applying your serum. It’s best practice to do this so that you eliminate any potential of causing unnecessary eye irritation.

2. Clean Your Face and Lashes

You will also need to wash your face and fully clean your eyes properly. Use a mild cleanser, and make sure to remove any makeup residue leftover from your eyeshadow or eyeliner, so that the lash serum can work its best.

3. Apply 1 Dip Of Serum To Your Upper Lash Line

Always apply a thin coat of your lash serum along your upper lashes, along the line of your eyelid at their roots. That’s because applying it to your lower eyeliner can cause irritation since it can seep into your tear ducts and block them. Apply the serum just as you would if you were using a liquid eyeliner.

Your lash serum will probably include either an applicator brush or a spoolie, which looks like a mascara wand. If it doesn’t then you can use a cotton swab to apply it, but use the applicator brush if possible.

Regardless of which of these tools you use though, start the application from the inner corner of your eye.

4. Blink Your Eyes

Blink your eyes 5-10 times, and this will transfer the serum from the upper lash to the lower lash without concern for the serum getting onto your iris or into your eyes.

5. Wait A Few Minutes Before Applying Eyeliner or Mascara

Wait a few minutes to let the serum completely dry before applying any eyeliner or mascara. This way, you can prevent the serum from getting on your eyeliner pen or mascara spoolie.

6. Repeat on a Regular Schedule

Consistency is key when it comes to lash serum, so you won’t see results overnight. It may even take a couple of months before you notice your natural lashes appearing more luscious. 

Therefore, you’ll want to make apply the lash serum regularly as part of your normal self-care morning or evening routine — or even both.

Excess Lash Serum Can Cause Irritation

Although some of us believe that more means better when it comes to lash serum, you definitely don’t want to apply more than you need. In fact, just one dip will be enough to coat both sets of eyelashes.

Adding too much lash serum won’t make your lashes grow any faster. Just a single light coat will do the trick, without causing the potential for irritation.

No need for excess! You’ll just waste the product, anyway.

And make sure that you clean whichever applicator you’ve used when you finish so that it’s ready to use next time and doesn’t contaminate the lash serum itself. Obviously, if you use a cotton swab as an applicator, then you can throw it away afterward.

Other Side Effects of Lash Serums

The most concerning unwanted side effect of lash serum is the famed phenomenon of lash serum getting in your eye, and causing your eyes to change color — permanently! This is highly unlikely to happen, but it can happen to those with light brown and green eyes. It is one of the big concerns with excess serum.

I’ve discussed the issue in more depth here.

If you are careful to not let the serum get in your eye, and don’t apply serum to your lower lash line or bottom lashes, you are unlikely to have this issue.

Stop using the lash serum immediately if you run into issues of irritation or color change.

Can You Use Lash Serum with Eyelash Extensions or a Lash Lift?

Yes, lash serum can be used even if you already wear lash extensions. However, you need to choose the right serum. If it contains oil, it will break down the glue holding your extensions on.

Flash The Lash

Using lash serum to make them thicker and more luscious is something that’s easy to do, and worth it, especially if you’re taking a break from having lash extensions applied. 

There are some common side effects, but if you are careful when applying your serum, apply a thin later, and don’t get it in your eye, you should be able to avoid any irritation or issues.

Now that you know how to apply lash serum correctly, you can look forward to having lashes that you can flash with confidence.
