There are hundreds of lash serums available on the market today. However, some people hesitate to use lash serum while wearing eyelash extensions. Eyelash extensions and lash serum are two beauty products that do the same thing: improve the look of your lashes. But can you use both of them simultaneously?
“Can you use a lash serum with eyelash extensions?”
As a lash artist, I get asked this question quite frequently.
Lash serums can be safely used with eyelash extensions. Eyelash extension wearers should apply the lash serum along the root of the lash line just as you would with a liquid eyeliner. Mascara applicators should be avoided as they would coat the entire lash and make volume extensions clump together.
But before you run off and buy a lash serum right away, let’s take a minute to learn the type of serums that are safe for extensions, what to look for, how to apply it, how to pick the right applicator, tips to make it work on your lashes, and the top lash serums made just for eyelash extensions wearers.
Why Use a Lash Serum With Eyelash Extensions
Most of our eyelashes become thin and weaken as we get older according to Dermatologists.
Usually, coconut oil or natural oil is recommended for conditioning them. But when you’re wearing lash extensions, coconut oil, or for that matter, any oil is a big NO-NO since they can be used to remove lash extensions at home!
Since eyelash extensions are applied directly onto your natural lashes, well you first need to have natural lashes!
I know… big surprise.
That’s where lash serums come into play.
Lash serums are peptide-infused formulas that stimulate lash growth. They work on improving the health of natural hair follicles, boosting their ability to grow stronger and thicker lashes. Applying lash serum regularly extends the phase of growth (telogen), making your lash growth cycle longer.
The healthier and stronger are your natural lashes, the more flexibility you will have with your lash extensions. You can even experiment with long and thick eyelash extensions or different styles when you have lush natural lashes.
Another advantage of having stronger natural lashes is that your lash extensions will last longer.
Since eyelash extensions are applied individually to your natural lashes, they will fall out gradually as your natural lashes shed.
However, if you can extend the growth cycle of your natural lashes with the use of a lash serum, you effectively gained more time between your lash extension refills!
Keeping your extensions longer means a fuller look and saving money.

Can You Use a Lash Serum with Eyelash Extensions? (5 Things to Know)
Absolutely! Several of my clients use a lash serum in combination with eyelash extensions without any adverse effects. It’s quite the opposite.
Here is my top 5 advice to ensure your lash serum and eyelash extensions will have a happy ending coexisting together.
1- Do Use a Lash Serum Without Oils
Some eyelash serums rely heavily on oils to achieve their intended results. Castor oil, coconut oil, and almond oil are three of the most common oils used to make eyelash serums.
It turns out that oil is a notorious solvent for the adhesive used when applying eyelash extensions.
Make sure to take a look at the ingredient list before buying a lash serum and avoid those that contain oils.
2- Do Not Apply a Lash Serum Right After Your Lash Appointment
A lash Serum should not be applied right after your eyelash appointment.
The adhesive used to affix an extension to your natural lash is cyanoacrylate-based. The adhesive typically takes about 4 hours to completely cure.
You should avoid putting additional moisture from a lash serum on your lashes during the curing period.
Once the 4 hours curing period is over, it is safe to use a lash serum.
3- Do Use a Lash Serum With Vitamins
Vitamins in a lash serum are key. They will keep your lashes nourished and hydrated.
Amongst all the vitamins to look for, Biotin is the most important one. Biotin is more than just a beauty vitamin. It’s involved in helping your body convert food to energy, and also makes it easier for you to have healthy skin, hair, and nails.
4- Do Not Apply a Lash Serum With a Mascara Wand
There are generally two main types of applicators when it comes to lash serums: a mascara wand or a liquid eyeliner.
The liquid eyeliner type is preferred when wearing eyelash extensions.
It allows applying the lash serum along the root of your upper lash line. Then, work your way along the lash line (from inner to outer corner).
You want to apply the lash serum along the lash line on the eyelid and not directly on your lash extensions. That’s why the liquid eyeliner type of dispenser is perfect for lash extension wearers.
A mascara applicator forces you to apply the lash serum on the entire lash. This is problematic for lash extension wearers, especially if you have volume lashes since it would essentially cause the volume fan to close.
The same concept applies to mascara with eyelash extensions. Using mascara with volume lashes would cause the volume fan to close and the lashes to mingle together in mascara.
5- Do Make It a Habit
To achieve the best results, a lash serum should be applied rigorously daily.
You should try to include the application of the lash serum in your morning regimen if you can.
How to Apply Lash Serum With Extensions
Lash serum is the best way to protect your lashes and keep them looking healthy. But, if you have extensions, applying serum can be tricky – it’s easy for the product to get stuck in the extension!
Here’s how to apply a lash serum with extensions:
Step 1: Choose the Right Product
Not all lash serums are made to be used with eyelash extensions. Make sure to read the label and choose a lash growth serum especially tailored for lash extensions.
Keep on reading because I will reveal the lash growth serum I have been recommending to my clients over the years and had very positive results.
Also, only use a lash serum that has a liquid eyeliner type of applicator. Avoid mascara wands.
Step 2: Do an Allergy Test
Before using it on the skin, test the serum by adding a drop of it to your neck, forearm, or other areas of the body.
Step 3: Clean Your Face
Clean your face with warm water to remove makeup, oils, dirt, and dust to create a clean surface for easy application and absorption of the serum.
Step 4: Apply The Serum
Grab the brush and apply the serum just like you would apply liquid eyeliner. Apply the lash serum along the root of your upper lash line from the inner corner to the outer corner of the eye.
Step 5: Let It Dry
Wait for a few minutes before applying any eye makeup around the lash line after the application of lash serum.

2 Best Oil-Free Lash Serum
Many products claim to help lashes grow longer and thicker but not all of them work as well as others.
In this article, I want to recommend 2 lash growth serums that I have personally tested over the years. Dozens of my clients had positive results with this lash serum while maintaining their eyelash extensions.
I am sure there are other lash growth serums of high quality out there. However, I would feel uncomfortable recommending a product I don’t have personal experience with.
So, here we go. Here are my two favorite lash serums for eyelash extensions!
EyEnvy® Lash Serum is a naturally-based, vegan lash serum that will help you achieve the look of long and luscious lashes.
EyEnvy® Lash Serum is made with highly concentrated ingredients which are clinically proven to promote eyelash growth in both length and thickness. It’s also safe for use on extensions, making it perfect for anyone who wears them!
You can use their store locator to find the nearest salon distributing this product. Unfortunately, they don’t sell online.
For eyelash extensions wearers who love RapidLash®, there’s good news. RapidLash® is perfect for use with extensions. It can nourish, strengthen, and thicken your eyelashes.
I have been recommending the RapidLash® growth serum to my clients for years now and this product has done wonders. Not only are my client’s lashes stronger, but they also grow longer and much faster.
The best part is that it’s easy to find in stores or online, which means you can always have some on hand!

Can You Use Latisse With Eyelash Extensions?
Latisse is a prescription treatment that can help you grow longer, fuller, and darker eyelashes. Latisse is an FDA-approved product with over 10 years of testing behind it. 
Many people are under the misconception that Latisse, a popular product for growing eyelashes, cannot be used with lash extensions. This is not true.
Latisse can be used in combination with eyelash extensions.
The presence of lash extensions would not interfere with the action of Latisse.
To use both products together, you should consult with a dermatologist first for safety reasons.
Note that prescription serums have reported side effects to alter the color of the iris and you must use it only at the advice of your doctor.
Can I Use Grande-LASH MD® Serum With Lash Extensions?
Yes, Grande-LASH MD® is a trustworthy eyelash growth serum for growing your eyelashes or strengthening them quickly.
It’s a water-based solution that will not affect the lash glue or extensions in any way and can help to retain the lash adhesive for a longer time.
Although I haven’t personally tried this product, Grande Cosmetics claims their lash serum is suitable for eyelash extensions.
You can find the Grande-LASH MD® serum here on amazon.
Lash serums are concentrated combinations of vitamins, amino acids, and peptides, and nutrients required to nourish and rejuvenate your natural lashes.
Using them is safe for your eyelash extensions when chosen and applied correctly.
You can choose from our top 2 lash serums (RapidLash® and EyEnvy®) knowing they are safe and have a proven track record with our clients.
Once selected, you can apply the serum on the lash line every morning just like you would for a liquid eyeliner. Wait for a few minutes for applying anything close to the eyes such as makeup and continue the routine for a month to see visible changes.
