1. Remove makeup with an oil-free remover or cleanser.

2. Apply one stroke of the serum only to your upper lash line (like an eyeliner). One dip is sufficient for both eyes.

Using more than instructed will not give you better results and might increase sensitivity: Don't do multiple applications or double dips. Don’t apply it on the lower lash line (the serum will be transferred to your lower lashes when you blink).

3. For best results, apply in the PM and allow the serum to work overnight. If applying in the AM - make sure the serum has fully dried before following with your makeup routine

How often?

  • First 12 weeks: Every day
  • After 12 weeks: 3-4 times per week (every other day)

Important

  • Avoid direct contact with the eyes
  • Do not use if you are pregnant, nursing or under 18
  • Keep out of reach of children
  • Patch testing is always recommended and if redness or irritation occurs, discontinue use
  • If you have any preexisting conditions, consult your doctor before use

FAQ

An eyelash serum is a specially formulated treatment designed to lengthen, thicken and nourish your natural eyelashes. Providing a kinder alternative to eyelash extensions, they typically contain a blend of ingredients to stimulate lash growth.

Eyelash Serums deliver active ingredients to the roots and lengths of the lashes to create the perfect environment for growth and to nourish and condition the lashes that are already there, prolonging the amount of time they stay attached and in turn creating the appearance of longer and fuller lashes. Head to our article ‘How Do Eyelash Serums Work’ to learn more.

Apply a small amount of the serum to a small area, such as the corner of your forehead, behind your ear, or the side of your neck. There should be no other products on the skin so that you can properly test this product.  Wait around 24 hours to see if you have skin sensitivity.

In short, eyelash serums are safe to use and are typically backed by rigorous testing and stringent quality control measures. As with all beauty products, different serums can affect people differently, which is why we always encourage patch-testing prior to using the product and ask that you consult your doctor before use if you suffer from any preexisting conditions.

This will depend on what point your lashes are in their cycle when you start to use the product. Some see longer lashes in as little as 25 days, but 12 weeks is when you should expect to see full results. Read more about lash cycles.

    Love this!

    My lashes were ruined due to using cluster lashes for so long, I had big gaps and they were so sparse. I’ve used this serum for 2months and have seen SUCH a difference. I was sceptical about this and if it actually worked but I’m so glad I went for it because I’ve now ditched the falsies and love my natural lashes. Picture is before and after, they’re even longer/fuller now as this isn’t the most recent pic I took. This stuff is insane!
