What Are Eyelash Growth Serums? How Do They Work?

Eyelashes that flutter every time you blink are a dream. 

They can transform the way you look and make your eyes look bigger. 

Raise your hands if you want to know how to give yourself fuller and longer lashes without using false ones. 

Turns out that a great way to achieve it is eyelash serums. 

The latest cosmetic craze is liquid gold tubes that give you longer, thicker, and more voluminous lashes in weeks. 

Eyelash serums have astounding promises, whether you’re a beauty fan or a cynic.

Many popular brands on the market compete to be the top choice, and one of the spectacular fights is Lumigan Vs Latisse.

But how do eyelash serums work? Let’s find out!

What are eyelash serums?

Cosmetic eyelash serums stimulate eyelash growth and health. 

They come in small tubes or bottles with a brush to apply the serum to your lash base. 

Vitamins, peptides, and other nutrients in eyelash serums strengthen and lengthen lashes over time. 

Eyelash serums increase lash health and attractiveness over time, unlike mascara. 

Regular application will give you longer, fuller, and more voluminous lashes in a few weeks.

Using a variety of ingredients, lash serums nourish and strengthen the lashes, and they fall into three primary categories based on their important active ingredients:

  • Peptide-based
  • Prostaglandin derived
  • Vitamin based

The most popular active ingredients, like Bimatoprost or Latanoprost, are Prostaglandin derived. 

Many popular brands contain these ingredients, like Lumigan, Latisse, Careprost, etc.

Latisse is FDA-approved for eyelash growth. 

However, many other serums are used off-label to achieve lash growth. 

Choosing the best one for yourself can be tough, and you might search for the right choice between Lumigan and Latisse. 

However, it is recommended to consult a specialist before using any product. 


Prostaglandins are naturally occurring fatty acid molecules present in most human tissues. 

In reaction to damage, inflammation, or stress, cells create signaling molecules that govern several physiological processes.

Prostaglandins regulate blood pressure, inflammation, immunological response, blood coagulation, reproduction, and digestion. 

In the context of lash growth, it lengthens the anagen (growth) phase of the hair cycle, boosting eyelash hair development.

How do eyelash serums work?

The working of eyelash serums depends on the active ingredient. 

Usually, they work on lashes with nutrients and ingredients essential for promoting growth. 

These ingredients also strengthen your lashes. 

The majority of eyelash serums contain vitamins, peptides, and amino acids that nourish and protect your eyelashes.

Eyelash serums typically contain active ingredients that function in one of two ways. 

Certain serums contain prostaglandin parallels that are designed to extend the growth phase of eyelashes. This results in longer, fuller lashes over time. 

Other serums contain peptides that assist in strengthening hair follicles and preventing breakage. 

This can prevent eyelash loss and encourage the growth of new, healthy lashes.


Bimatoprost is a prescription medicine that lowers intraocular pressure and treats Glaucoma.

However, it promotes lash development in eyelash serums off-label.

Bimatoprost lengthens the eyelash development phase (anagen). 

It is prostaglandins derived, which naturally governs cell development and inflammation. 

Bimatoprost binds to Prostaglandin receptors in hair follicles, increasing Keratin synthesis and decreasing hair’s Telogen (resting) phase.

Longer, thicker, and darker lashes develop.

Bimatoprost may cause iris color changes, skin pigmentation around the eyes, and drug interactions. 

Therefore, only use bimatoprost-containing products under medical supervision.

Lumigan and Latisse are popular products that contain Bimatoprost. 

Way to use eyelash serum

Follow these basic steps to apply an eyelash serum:

Cleanse your face: Before applying an eyelash serum, clean and dry your face. This ensures that the product can be correctly absorbed.

If you wear mascara or other eye makeup, remove it before applying the serum.

Apply the serum: Using the serum’s applicator brush, apply a tiny quantity of the serum to the root of your upper lashes. Avoid getting the serum into your eyes.

Let it dry: Allow the serum a few minutes to dry before applying additional products or stroking your face.

To be effective, eyelash serums must be applied consistently, once per day. 

Each eyelash serum has its own directions. To use a product safely, read the packaging and instructions. 

Discontinue usage and see a doctor if an eyelash serum causes irritation.

Are eyelash serums safe?

If you use serums correctly and under the guidance of a specialist, yes, they are safe. 

You should follow the instructions of the expert and the directions on the label to use the serum for the best and safe results. 

You should not use the serum if you are wearing any contact lenses or makeup. 

Remember that on applying, if you experience any burning sensation, itchiness, color changes in hair, eyelid darkening, pigmentation, or hair growth in areas you don’t wish but the serum touches, you should immediately see a doctor. 

The difference between Latisse and over-the-counter lash serums

Latisse and over-the-counter lash serums increase eyelashes. All these serums products lengthen, thicken, and darken eyelashes, but there are some key differences.

Where Latisse is an FDA-approved serum for lash growth, others are not. 

Bimatoprost, a prostaglandin analog, promotes eyelash development in Latisse. 

Generally, this serum must be used constantly for 12 weeks to obtain complete results. Latisse is safe when used as prescribed by a doctor.

However, there are some over-the-counter lash serums that drugstores, internet retailers, and beauty supply stores sell. 

These products contain vitamins, peptides, and other nutrients to nourish lashes. 

Over-the-counter serums like Lumigan may increase lash length, fullness, and darkness but don’t contain Latisse’s active component or promote eyelash development. Latisse results may vary and take longer to reach.

These over-the-counter lash serums offer nourishing nutrients but lack Latisse’s main ingredient and are less efficient at growing eyelashes. 

Talk to a doctor or beauty expert about your needs and preferences to find the right product.


In conclusion, eyelash serums are popular for lash growth. 

Whether you use Latisse (Bimatoprost) or an over-the-counter serum, these products increase lash health, length, fullness, and darkness. 

Eyelash serums feed and stimulate hair follicles for lush, fluttery lashes. 

To get the most benefits and minimize negative effects, pick a product that’s perfect for you and use it as advised. 

With consistent use and the appropriate eyelash serum, you may have longer, fuller lashes that frame your eyes and make you feel confident and gorgeous daily.
