April 20, 2026

Who hasn't dreamed of having the most voluminous, long, and curled eyelashes? Eyelashes that take your breath away and move like the flutter of a butterfly's wings. Eyelashes that make your eyes stand out and look magnificent. If you belong to this group of dreamers, we have good news for you. Today we bring you a complete guide to eyelash serums, your best ally for achieving those stunning lashes you've always dreamed of.

What is an eyelash serum and what is it for?

Let's start by defining what an eyelash serum is.. Well, it's a product designed to strengthen and stimulate the growth of eyelashes.. It achieves this thanks to its composition, made from proteins and enzymes that activate the eyelid follicles, the main agents responsible for their growth. Therefore, if you use it regularly, you will see how in just eight weeks your eyelashes look stronger, healthier, and fuller. because they are more hydrated and longer, and because their fallout is considerably reduced. How and when should you apply eyelash serum? The ideal time to apply it is at night, just before going to sleep, with your face completely clean and free of makeup, especially in the eyelash and eyelid area.

You must apply it to the entire length of your lashes, paying special attention to the root, as this will allow the product to penetrate the follicle better. Most formats include a brush to make application much easier.

However, it is a treatment that requires consistency to achieve optimal results.

So, night after night, serum needs to be a key part of your skincare routine. Oh! And keep in mind that it's NOT for eyebrows. That's one of the many myths circulating online.

What types of serums are there?

Although all serums share the common goal of achieving the objectives we just mentioned, it is true that some focus more on certain properties than others. So, we can find serums specialized in lengthening eyelashes, increasing their volume, or strengthening them. To choose the most suitable one for you, you have to look at the biggest problem with your eyelashes. Do they fall out a lot? Are they very short? Or, on the contrary, are they very long but so fine that they go almost unnoticed? In the first case, you'll have to opt for a strengthening serum, in the second for an eyelash growth serum, and in the third for one that increases their volume. It's that simple. And if you want an all-in-one solution, don't worry, because below we show you a list of the best eyelash serums of 2021
