How Lash Serum Works?

Biotin, also known as vitamin B7, is often mentioned as beneficial for hair, nails, and skin.

It has the potential to stimulate hair growth, improve your nail and hair health, and act as a lash conditioner. Biotin is said to strengthen the keratin for thicker lashes.

Pumpkin Seed Extract

Pumpkin seed extract and pumpkin seed oil target hair loss by blocking hormones and enzymes that cause the loss.

Hyaluronic Acid

Hyaluronic acid is another common ingredient in serums that delivers hydration to dry, damaged hair and improves the lash’s flexibility. Thanks to this ingredient, you’ll have fuller lashes.


Panthenol, or provitamin B5, just like hyaluronic acid, acts as an eyelash conditioner. It makes the hair more flexible, prevents breakage and provides a fuller appearance.

Castor Oil

Pure castor oil can potentially prevent hair loss and stimulate new lash growth.

Step-By-Step Guide For Using Eyelash Serum

Since we got all the basics out of the way, it’s time for you to learn how to apply lash serum step-by-step.

#1 Remove Your Contacts

Every eyelash enhancing serum is based on chemical ingredients that shouldn’t get in touch with your eyes or contact lenses. That’s why before you grab the applicator, make sure to remove your contacts. You can put the lenses in after 15 to 30 minutes of the application.

#2 Take Off Your Makeup

Applying lash growth serum while you have makeup and mascara on makes no sense. That’s why makeup removal should be your next step.

Use your regular cleanser to take off all the makeup, dirt, oil accumulated on your skin. You’ll have a fresh, clean face and eyelashes for the serum to do its magic on.

#3 Apply Over The Upper Lash Line

An eyelash growth serum packaging can feature various types of applicators.

Some come with a one-time applicator that you should throw away after use, while others have a brush-like tip that reminds of nail polish applicators but a significantly smaller version.

After reading the bottle’s instructions, you can open the packaging and add a thin layer over the roots of the upper lash line.

Start at the inner corner and slowly make your way to the outer corner of the eye.

This process is very similar to applying liquid eyeliner, so you will surely grasp the technique on the first try. Make sure that the product doesn’t get into your eyes.

#4 Wait Before Applying Makeup

This step is quite essential! Now that you know how to apply eyelash serum, you also need to know that you should wait five minutes before using any other eye products.

Forget about lash curlers, lash extensions, false eyelashes, mascara, eyeshadow, eyeliner, or any other product right after the lash growth serum. Also, don’t go to sleep right after the application.

#5 Protect Your Lashes

Be careful and gentle with your lashes! You shouldn’t rub your eyes or take off makeup aggressively. This can cause damage to the hair follicles and lead to lash loss.

#6 Be Patient

Be patient and consistent with the use of the growth serum. All good things take time! You need to apply it according to the instructions, and for most serums, that’s in the morning and at night.

The final result will be luscious lashes that make your eyes even more gorgeous.

If you’re bad at creating habits, leave your serum in a place where you’ll see it, such as right next to your bed or in the bathroom. Don’t apply double layers if you miss a day or two.

If you’ve been eyeing numerous lash serum brands online and you’re interested in purchasing, the choice can be pretty overwhelming.

There is no need to be worried about the application because they all come with instructions, and you can always follow our detailed guide.

For example, if you want to know how to apply Revitalash, all you need to do is use the brush and swipe it over your upper lashes, just like we explained.

Most other products feature a similar technique, the only difference will probably be the applicator.

Common Mistakes That You Should Avoid

Too Much Serum

Using excess serum doesn’t mean that your lashes will grow faster!

These products are saturated with ingredients, and there is no need to apply multiple layers. A single dip should be enough for the lash lines of both eyes.

So many women are under the impression that they’ll get longer lashes if they drown theirs in serum.

Since that’s not the case, you’ll only be spending product without reason, oversaturating the eyelashes, and risking possible irritation from the excess amount of product.

Applying On The Bottom Lash Line

The upper lash line is the only place where you should use the eyelash serum. The chances are if you apply it on the lower line, the product will get into your eyes.

This is how irritation can happen; it’s simpler and smarter to stick to the rules.

When you apply the product on your upper lashes, a part of it gets on the lower lashes when you blink so that it will have an effect everywhere.

Final Conclusion: Is it Safe to Use Eyelash Serum?              

As long as you follow all the instructions, using lash serum is entirely safe. You can forget about false lashes and grow yours without putting in too much effort.

Opt for a reputable brand with dermatologically tested products. If you want to be even safer with your choice, don’t hesitate to consult your doctor.

Now that we went over the steps on how to use a lash serum, all you need to do is get your product and start using it consistently.

The results won’t come fast, and it can take months before you notice the difference. Just let the product do its magic and document the progress while you’re waiting.
