What does eyelash serum contain?

Do you also find it confusing to navigate the world of eyelash serums? The exact ingredients of the eyelash serum vary from product to product. That’s why in this article, you’ll be able to see the precise ingredients that strengthen the lashes.

How does eyelash serum help?

Generally, eyelash serum nourishes your eyelash hairs from the root, which allows the lashes to grow long and beautiful, as well as making them fuller, darker, and incredibly strong. Therefore, you transform your small, perhaps fragile lashes into lush and full lashes.  

The amazing thing is that you will already be able to see a difference after 4-8 weeks. Here, you can both feel and see a difference. Your lashes should hopefully be even stronger and more beautiful to look at after such a short time. Some people even experience changes before 4 weeks.

How to use eyelash serum?

One thing that is the same for all three products is that the eyelash serum should be applied once a day and on clean lashes. It is therefore important not to apply makeup immediately afterwards. This way, the serum works optimally. The eyelash serum should be applied right at the base of the lashes, at the upper lash line.

We recommend using the serum on cleansed lashes before going to bed. This way, the serum will have time to work overnight and perform miracles for your lashes.

Eyelash serum for use with eyelash extensions

If you already use eyelash extensions, it is a really good idea to use eyelash serum. This is because it can be hard on your natural lashes to wear eyelash extensions. The fake lashes can be heavy on your natural lashes, causing them to break or fall off faster than usual. Therefore, using a serum is an incredibly effective way to strengthen your own lashes, especially when using fake lashes.

If you have eyelash extensions, the application of the lash serum is slightly different. Instead of applying it directly to the lash line, you should apply the serum to the extensions themselves. This way, you can increase the longevity of your extensions and extend the lifespan of your natural lashes.

Eyelash serum for sensitive eyes

If you have very sensitive eyes, you can always test the eyelash serum before use, for example on your hand. If you want to be completely sure, both RevitaLash and Sanzi Beauty are 100% vegan, without perfume and parabens. Therefore, you will avoid stinging and redness if you do not get the serum directly into the eye.

All eyelash serums that you buy in Europe are approved products.

Good luck on your eyelash journey. We hope that the guide has helped you and that you are now ready to transform your little lashes into irresistibly long eyelashes.
