No more extensions, with a good eyelash growth serum and an excellent mascara, the doe-eyed look can be there in the blink of an eye!

Thicker, longer lashes in a month (or so!)? It's possible!

I too was very skeptical and not very convinced by all that "serum booster" and stuff, but that was before.

For the impatient ones who, like me, don't want to wait for castor oil to take effect after six months, and who want to have eyelashes spread out and a doe's look as quickly as possible, here are the products you’ll need!

But before a few important information to keep in mind before buying your next eyelash growth serum.

Which eyelash serum is the best?

The best eyelash growth serum is the one that works quickly and effectively. You always have to try to get the beauty product that goes with your expectations.

Before buying an eyelash serum, learn about its ingredients and make sure it is safe for your eyes and the skin around them.

Compare prices because the most expensive products are not always the most effective.

On the other hand, very low priced eyelash serums may not have the required standards.

It is important to pay attention to the product reputation you buy, the applicator and the formula.

If you can, get a sample to see how easy it is to apply and whether the product does have any technical issues (not adapted applicator, too liquid, too thick...).

The best eyelash serums have a pointed brush as an applicator that spreads the product directly onto the lashes.

This ensures that the lash follicles are well nourished and that the process of lash growth is accelerated.

Before using it for the first time, read the instructions that come with it and look at any precaution to take care and the potential side effects.

How do I use an eyelash serum?

For the eyelash serum to work at its best, it must be used consistently.

The application should be carried out in the evening generally, ideally at bedtime.

The average treatment time with eyelash serum is 3 months and after this time, the product maintains the results already obtained.

It may vary depending on the eyelash serum, but the first results should be visible after the first 4 weeks of use.

Most eyelash serums strengthen lashes and increase their length and volume. Some products can also make your lashes look darker and brighter.

How the eyelash serum is applied is extremely important. Most eyelash serums have a small, pointed brush that is used like a liquid eyeliner.

Use the applicator directly on the upper and lower lashes and wait for the product to dry.

The eyelash serum is absorbed directly by the eyelash follicles and provides nutrition and hydration.

If you want your lashes to be shiny, you should choose an eyelash serum with a mascara type brush that will spread the product along the length of the lashes.

How do eyelash serums work?

How an eyelash serum works depends on two things: the ingredients and the method of application.

Before applying the product, make sure your skin and lashes are clean from makeup or cream.

Dry them with a cotton towel or pad before applying the eyelash serum.

For the active agents to be fully absorbed, the skin must be completely clean. Your lashes will gain in length and volume provided the formula of the lash serum is rich in essential vitamins and peptides.

Creatine and Vitamin E promote length while Aloe Vera and Green Tea soften the skin and have anti-inflammatory properties.

Now an overview of the best eyelash growth serums on the market.

RevitaLash Advanced Eyelash Conditioner Serum



  • Not tested on animals
  • Easy to use
  • Results: well separated lashes, fewer lashes fall out, protected, shiny, fortifies/strengthens, nourishes
  • Relatively high price
  • Results: if you stop the treatment, the effect disappears, lashes are not curved or flexible.


Aqua, Glycerin, Biotin, Cellulose Gum, Phenoxyethanol, Chlorphenesin, Disodium Phospahte, Phosphoric Acid, Dechloro Dihydroxy Difluoro Ethylcloprostenolamide, Butylene Glycol, Calendula Officinalis Extract, Panax Ginseng Extract, Serenoa Serrulata Extract, Camellia Sinensis Extract, Swertia Japonica Extract, Triticum Vulgare Germ Protein, Pentylene Glycol, Biotinoyl Tripeptide-1, Octapeptide-2.

A relatively effective product, a slight growth is noted but nothing exceptional either. Some results can be seen after 3 weeks of use.

On the other hand, after a few weeks, it can irritate the eyes by drying them out. So if you have sensitive eyes, I do not recommend it at all.

When you stop using the product, the lashes gradually regain their initial size or may even fall out.

Nanolash Eyelash Growth Serum


  • Laboratory Verified Ingredients
  • No allergic reactions
  • Naturally longer and more voluminous lashes
  • Product lasts long


  • Changes too long to appear


Aqua, Trifluoromethyl Dechloro Ethylprostenolamide, Euphrasia Officinalis Extract, Sodium Chloride, Alcohol Denat, Benzalkonium Chloride.

At first glance, Nanolash makes a good impression with its performance promises on the website as well as its promise of longer, darker lashes.

Thanks to a precise brush its bristles are extremely flexible. The brush has an ideal pointed tip. As a result, it picks up the right amount for an application.

Unfortunately, a little disappointed with the time it takes for the product to take effect on lashes (6 to 8 weeks compared to the 4 weeks promised by Nanolash) .

In my opinion, the Nanolash serum is the best option for all girls who are looking for an effective, elegant and natural product at a medium price.

JEUXLORE - Eyelash Growth Serum

Incredible results with Jeuxloré


  • Complex of good quality active ingredients
  • Serum suitable for sensitive skin
  • Easy to apply on the eyelid
  • No allergic reactions and good serum tolerance


  • Takes longer time than other products to get longer eyelashes


Aqua, Pentylene Glycol, Glycerin, Polyglyceryl-4 Caprate, Sodium Hyaluronate, Phenoxyethanol, Ethylhexylglycerin, Panthenol, Tocopherol, Alcohol, Bio- Tinoyl Tripeptide-1, Isopropyl Cloprostenate.

Lash Superlative Serum is a suitable lash fortifier with an improved and effective formula.

As a result, beautiful, voluminous and long lashes are promised.

Experiences after using Jeuxloré Lash Serum are quite positive. This eyelash strengthening serum is easy to use and has also proven to be a good base for lash care.

However, in some tests this eyelash boosting serum got positive results only after 9 to 10 weeks of continuous use.

REALASH Eyelash Enhancer


  • Intensive eyelash care
  • Tolerance tests carried out by the manufacturer
  • No allergic reaction
  • Refundable


  • Lash growth but not of 83% as promised


Aqua, Propanediol, Panthenol, Glycerin, Biotinoyl Tripeptide-1, Acorus Calamus Root Extract, Acrylates/C10-30 Alkyl Acrylate Crosspolymer, Calendula Officinalis Flower Extract, Dechloro Dihydroxy Difluoro Ethylcloprostenolamide, Disodium EDTA, Ethylhexylglycerin, Equisetum Arvense Leaf Extract, Hydrolyzed Silk, Linum Usitatissimum Seed Extract, Phenoxyethanol, Propylene Glycol, Serenoa Serrulata Fruit Extract, Sodium Hyaluronate, Sodium Hydroxide.

With Realash you'll have well-groomed lashes in no time!

The price of Realash eyelash serum is significantly higher than other manufacturers in this market.

For intensive eyelash care, this product is pretty good.

Even if it is a serum specifically designed to activate and promote lash growth, the promised growth of 83% that the brand praises might be a little bit pretentious.

But the bottom line is that the Realash eyelash enhancer serum with its scientific proofs and many satisfied women who have tried it could make it a potential bestseller in the eyelash growth serum market (if not already!).

M2 BEAUTE Eyelash Activating Serum 5 Milliliter


  • Some natural ingredients
  • Promotes lash growth
  • Easy to apply with its liner brush the right dose is applied
  • No side effects or reactions


  • High price


Aqua, Caprylyl Glycol, Phenoxyethanol, Hydrolyzed Glycoaminoglycans, Panthenol, Biotin, Hyaluronic Acid, C12-15 Alkyl Benzoate, Triethanolamine, Acrylates, C10-30 Acrylate Crosspolymer, Methylamino Dihydro Noralfaprostal, Sodium Lactate, Sodium PCA, Sorbitol, Proline, Sodium Chloride, Alcohol, Sodium Phosphate.

This very powerful activation serum contains the highly effective DND complex. This carefully dosed active ingredient stimulates the lash roots, resulting in a more complete growth phase for stronger lashes.

It is a non allergic product, even for sensitive eyes but can leave a discomfort feeling for a minute or so after application.

The M2 Lashes Eyelash Activating Serum, is a good serum that promotes growth and strengthens lashes while providing nourishing care.

The only drawback is that it is much more expensive than most lash fortifying serums on the market.
