DIY Natural Eyelash Serum


Jealous of those beautiful long eyelashes that others have? Don’t worry, me too. I don’t know who decided that long eyelashes made people more attractive, but it is just one of the many expectations that society has set that separate “beautiful” people from others.

Anyways, this post is not about the injustices and unrealistic expectations of society, it is about a DIY Natural Eyelash Serum that will boost the length and thickness of your eyelashes. That’s right, not only does it avoid all those scary chemicals in store formulated serums, but it is also cheap! Very useful for someone who has a limited budget like me 🙂

My eyelash serum recipe is very simple and requires only two ingredients. Of course, you can alter the recipe to your liking.

Eyelash Serum Materials

To make this serum you will need:

  1. 0.5 oz empty dropper bottle
  2. 0.20 oz of Castor Oil
  3. 0.20 oz of Vitamin E oil
    1. Since I don’t use a lot of vitamin E, I bought it in capsules so that it stays fresh longer.
  4. optional: lavender essential oil
  5. scale
    1. I have two scales: One that weighs up to 100g and another one that weighs up to 500g.
    2. I got the smaller one at first because it was cheaper and I only needed to weigh small items, but I eventually purchased the bigger one because I needed to weigh heavier substances.
    3. Therefore, I recommend that you buy the bigger scale from the start because it is more cost effective than buying two scales.
    4. Of course, if you are only doing this project, then you can eyeball equal amounts of castor oil and vitamin E oil into the dropper bottle, but trust me, once you enter the world of DIY skincare, there is no backing out… (and you’ll want to do more projects that require a scale 🙂


  1. clean the area that you are planning to work on
  2. line up all your materials
  3. open the empty dropper bottle and place it on the scale
  4. tare/ zero the scale
  5. add in vitamin E oil until there is 0.20 oz inside the bottle
  6. tare/ zero the scale again
  7. add in castor oil until there 0.20 oz inside the bottle
  8. optional: add in a drop of lavender essential oil
    1. I always buy my essential oils from Rocky Mountain Oils because they have the purest essential oils at the best prices.
  9. Close the bottle and shake it to mix the oils together.
  10. Stand back and admire your creation.

Benefits of Vitamin E

Vitamin E is a fat-soluble antioxidant. It helps to fight free radicals and gives your skin the necessary nutrients to regenerate and remain healthy. This keeps your eyelids in optimal condition so they can grow healthy eyelashes.

Benefits of Castor Oil

Castor oil is rich in vitamin E (that’s what we just talked about!). Although there is no scientific research supporting that castor oil promotes eyelash growth, it does help moisturize your eyelashes to prevent premature damage. It is a very thick oil, so a little goes a long way.

Benefits of Lavender Essential Oil

Lavender essential oil has numerous uses: from relaxing to healing. Not to mention, it is one of the gentler essential oils, so it is less likely to irritate your skin. I personally do not put it in my eyelash serum because I found that after using it for a few weeks, my eyes started to sting when I applied it. You can always give it a try, but stop if you notice any irritation.

How To Apply

  1. Apply the eyelash serum at night before you go to sleep
  2. make sure your eyelashes and eyelids are free from all mascara and makeup
  3. Put a drop on your finger, rub your two pointer fingers together and put it on your eyelashes
    1. Do not touch the dropper when you put it on your finger so you do not contaminate the rest of your serum when you close it
  4. Make sure you also put it on the roots of your eyelashes so it can absorb the nutrients
  5. Try not to get any into your eyes, but in my experience, nothing bad happens when I accidentally do.
    1. To be safe, you should wash it out if any gets into your eyes.
  6. You can use any leftover serum on your fingers for your eyebrows.
    1. This will help you get thicker and fuller eyebrows.

My Experience With My DIY Eyelash Serum

To begin, I already had decently lengthed eyelashes (thank you genes), but who doesn’t want longer and healthier eyelashes? I have tried a few recipes and the one with only castor oil and vitamin E worked the best for me. When I began using this serum, I was able to tell a huge difference. Not only did the length of my eyelashes increase, but the number of eyelashes that I had increased as well. Some eyelashes even started growing out higher parts of my eyelid away from the normal line of eyelashes. Many of my cousins mentioned that my eyelashes got longer. However, my eyelashes did not keep growing. They reached a certain length and just stayed there. Sadly, my eyelashes are not to the point where it looks like I’m wearing falsies, but I’ll take what I can get. I still apply the serum every night to maintain the length.


Unfortunately, I did not take any before images.  I only have after images.  These pictures are after I consistently used this serum for 4 months.

I did not alter my eyelashes or apply any makeup in these pictures.
