Eyelash Homemade Serum: DIY Guide for Naturally Longer, Healthy Lashes

by: Linda Robison / Facial Fitness Specialist

Looking for a natural way to condition lashes without chemicals? Here’s my go-to recipe.

Why I Love Homemade Lash Serum

I’ve always wanted fuller lashes. But harsh chemicals and expensive serums never felt right. So, I turned to something simple: a homemade eyelash serum. Natural, safe, and budget-friendly.

This little recipe has become a favorite part of my routine. And I think you’ll love it too.

Why try a homemade eyelash serum?

Most store-bought lash serums contain synthetic chemicals. Some even use prostaglandin analogs (PGAs). These can cause skin irritation, dark eyelids, or, rarely, changes in eye color.

A natural serum avoids those risks. Gentle oils and vitamins nourish your lashes instead. They protect against damage from age, mascara, and daily stress. 

Best of all, you know exactly what’s in it.

Ingredients at a glance

• 1 tsp castor oil
• 1 tsp coconut oil (or jojoba)
• 1–2 drops vitamin E oil
• 1 drop lavender oil (optional)

Key ingredients for stronger lashes

Here are the powerhouse ingredients I use:

• Castor oil: Omega-6 fatty acids and vitamin E. Known for encouraging hair growth.
• Coconut oil: Deep hydration to reduce lash breakage. Swap for jojoba oil if you’re prone to clogged pores.
• Vitamin E oil: Antioxidant support for healthy hair follicles.
• Lavender oil (optional): May boost lash growth. But use carefully near the eyes.

Instructions:

1. Combine ingredients in a small glass dropper bottle.
2. Swirl gently to mix.
3. Dip a clean mascara wand or cotton swab.
4. Apply a thin layer along your lash line before bed.
5. Rinse off any residue in the morning.

Pro tip: Always use a fresh applicator. No double-dipping.

Patch test first

Always test new products on your wrist before applying near your eyes.

• Dab a small amount on your inner wrist.
• Wait 24 hours.
• If redness or itching appears, skip using it on lashes.

How to apply safely

A few golden rules:

• Never let the serum get into your eyes.
• Use a clean wand each time.
• Apply only a thin layer. More isn’t better.
• Store in a cool, dry place.

If it does get into your eyes, rinse with cool water right away.

Tips for best results

Be patient and consistent. Apply nightly for 4–6 weeks to see results. A little goes a long way. Over-applying just leaves lashes greasy.

Bonus: This same serum works on brows. Try it on thin spots for extra fullness. Also see Why Eyebrows Are Important.

Lash serum ingredients: The science

• Castor oil: May help stimulate growth. Research shows it supports hair health.
• Coconut oil: Reduces protein loss in hair. Strengthens and conditions lashes.
• Vitamin E: Improves circulation, nourishes follicles.
• Lavender oil: Early studies suggest it promotes hair follicle growth.

Natural doesn’t mean instant. But over time, these oils can help lashes look healthier and fuller.

Final takeaway

For me, this eyelash homemade serum is about self-care. Not vanity.

It’s a gentle way to nurture lashes, avoid chemicals, and save money. Results may vary, but consistency makes a difference.

If you’re looking for a natural lash boost, give this serum a try.
