5 DIY Lash Serum Recipes for Lovely + Long Lashes (2024)

Have you heard of lash growth serums? Commercial serums work to strengthen and enhance your lashes and brows, making them shinier and fuller looking. And, no surprise, they can be super pricey! Also not a surprise—you can make a quick and effective DIY lash serum at home with just a few simple ingredients.

Just like our skin and hair dries out in winter, so do our eyelashes. So you may find that your lashes need a little TLC year-round or just one or two seasons a year.

And if you have an overplucked eyebrow disaster on your hands, try this castor oil brow serum.

DIY Lash Serum Benefits

I've made this lash serum recipe a few times and found it quite effective (it helped grow back my eyebrows after an overzealous plucking, and it filled some sparse spaces in my eyelashes).

But it's not just the conditioning benefits it contains, DIY eyelash serum also helps to:

• Prime eyelashes so mascara adheres better.
• Smooth and seallashes so they feel softer.
• Repair damage caused by too much heat, sun, and makeup.
• Nourish lashes and encourage them to grow more quickly.
• Hydrate lashes so they are flexible and less prone to breakage.

Ingredients

Hyaluronic acid powder: Hyaluronic acid can hold a significant amount of water, making it an excellent moisturizing agent. In a lash growth serum, it helps to keep the lashes soft, hydrated, and flexible.

Distilled water: Hyaluronic acid powder dissolves best in cool distilled water. Distilled water also lets you customize the texture of the serum so it's not too thick or too thin.

Aloe vera gel: Aloe vera gel is known for its soothing and moisturizing properties. It helps to condition the eyelashes, making them softer and potentially reducing breakage (so they grow longer). Aloe vera can also have a calming effect on the sensitive skin around the eyes.

Glycerin: Glycerin is a humectant, meaning it attracts and retains moisture. In an eyelash serum, glycerin helps to keep the lashes hydrated, preventing them from becoming dry and brittle.

Sweet almond oil: An optional ingredient in this lash serum, sweet almond oil provides nutrients, including vitamin E, which can nourish and strengthen the eyelashes. It may help to prevent breakage and promote healthy lash growth.

Vitamin E: Known for its antioxidant properties, vitamin E protects the lashes and skin around the eyes from free radicals, which may contribute to premature aging. It also nourishes the hair follicles and promotes overall lash health.

Open the tube and place a funnel on top. Combine the hyaluronic acid with cool water and swirl to dissolve.

Add the aloe vera and glycerin and swirl. Then add the almond oil and vitamin E into the tube.

Step 3 | Swirl

Replace the lid and swirl to combine. Gently swirl the serum again before applying.

Hint: Hyaluronic acid (HA) dissolves best by itself in cool water. So I recommend adding it to the mascara tube first, then swirling or shaking it until combined.

If you have trouble getting it to blend properly, use a toothpick to break apart any lumps before adding the remaining ingredients. You can also mix the HA with the water in a small bowl before pouring it into the mascara tube.

Substitutions

Oil — For some people, oil can cause pain and irritation if it gets in the eyes. If you have sensitive eyes or if you know for a fact that oil causes issues for you, leave the sweet almond and vitamin E oils out of your lash serum, and use extra glycerin instead.

Hyaluronic acid — You can omit this ingredient or use marine collagen or keratin protein instead.

Eyelash Growth Serum Recipe Variations

1. Oil-Free Aloe + Glycerin Lash Serum

I used to use a simple lash growth serum made from 50% aloe vera gel and 50% glycerin. This simple recipe leaves out all oils so it's gentle on the eyes, perfect for those with sensitive peepers.

• 1 teaspoon glycerin
• 1 teaspoon aloe vera gel

2. Castor Oil Growth Serum

You can leave out the aloe vera and go with ¾ castor oil with ¼ vitamin E oil. Castor oil is great for hair growth, but it can cause eye irritation in some people.

• 1 capsule vitamin E
• 1 teaspoon castor oil

3. Vitamin E Lash Strengthening Serum

If you find castor oil irritating, try just using vitamin E. Add a tiny bit of fractionated coconut oil for an extra dose of moisture.

• 1 teaspoon (3-4 capsules) vitamin E
• A few drops of fractionated coconut oil

4. Argan Lash Conditioning Serum

Try argan oil or a combination of argan, avocado, and almond oils to create a powerhouse for conditioning and strengthening your lashes. You can even apply it to eyebrows if you’re looking to create a thicker and stronger brow line.

• 1 tspargan oil
• ½ tspavocado oil
• ½ tspalmond oil

Storage

I use a 10 ml empty mascara tube with a spoolie brush that makes the serum easy to apply to the length of your lashes. But you can also use a 5 ml empty lash serum bottle with a wand that's easy to use along the lash line.

This set and this one both come with both applicator tools. Plus you get a tiny funnel to make adding the oils easier.

If you want to use castor oil, you can buy the oil with ready-to-go serum applicators.

You can also combine the homemade lash serum in a small jar and apply it with a cotton-tipped swab. Or apply 2-3 drops of oil onto your finger and gently massage into lashes and brows.

Usage

Shake the lash growth serum before each application then apply it to the lash line and also on the lashes if you're using a mascara wand.

I apply it nightly to clean lashes (and brows) and wear it overnight to make sure it dries on the lashes. Use daily and you’ll see improvement in 2–4 weeks.

Try to not get the serum in your eyes when applying; it doesn't feel great!

Don't apply to the lower lash line or inner tear duct area. Reduce frequency or discontinue using if any eye irritation develops.

It's best to make a fresh batch once a month. Halve the recipe if needed.
