But here’s the good news: 

You don’t have to risk your eye health to achieve longer, fuller lashes. Many eyelash serums and growth boosters on the market can help with lash growth without these controversial ingredients.

Ready to discover these eye-friendly alternatives? Let’s look at 4 prostaglandin-free eyelash serums that show promising results.

Gentle Lash Boosters: 5 Eyelash Serums Without Harsh Ingredients

Looking for fuller lashes without the risks? These serums skip the harsh stuff but still deliver results.

Growing, Lengthening, Thickening, Conditioning

1: Scandinavian Biolabs Bio-Pilixin® Eyelash Growth Serum

  • Description:

    This all-in-one lash booster from Danish company Scandinavian Biolabs is the Rolls-Royce of plant-based eyelash serums. It helps improve lash growth, density, length, fullness, and strength.

  • Pros:
    • 150-day money-back guarantee
    • Dermatologically tested
    • Hygienic jade roller applicator (helps reduce product oxidation)
    • Recommended by dermatologists, trichologists, and skin experts
  • Cons:
    • High-end price point
Why Choose Scandinavian Biolabs Eyelash Growth Serum?

Scandinavian Biolabs Eyelash Growth Serum promises longer, thicker, fuller lashes without the risks tied to prostaglandin-based products.

This formula’s key ingredient is Curcuma Longa Callus Conditioned Media, a peptide from the Curcuma plant.

This ingredient has been clinically tested for hair regrowth by Vytrus Biotech in Barcelona, Spain. For anyone unhappy with their lash length or noticing increased lash loss, this ingredient holds potential.

But that’s not all.

The serum is also packed with other lash-boosting ingredients like Myristoyl Pentapeptide-17, Biotinoyl Tripeptide-1, and various amino acids. These work together to thicken, lengthen, and nourish your lashes. What sets this product apart is the company behind it. Scandinavian Biolabs’ sole focus as a company is hair regrowth. They’ve put in serious research to find ingredients that truly help with hair growth. Unlike companies that dabble in a bit of everything, Scandinavian Biolabs is laser-focused on healthy hair, 24/7.

“I started using this serum after lash extensions, about 1.5 months ago. At first my lashes were so weak and thin. Now my lashes are so full and beautiful. Also this serum doesn’t irritate my eyes at all. Great serum, recommend this!” – Maarja

Ingredients:

Aqua, Curcuma Longa Callus Conditioned Media, Pentylene Glycol, Phytic Acid, Myristoyl Pentapeptide-17, Glyceryl Glucoside, Biotinoyl Tripeptide-1, Sodium PCA, Sodium Lactate, Arginine, Aspartic Acid, PCA, Glycine, Alanine, Serine, Valine, Proline, Threonine, Isoleucine, Histidine, Phenylalanine, Amaranthus Caudatus Seed Extract, Biotin, Panthenol, Sodium Benzoate, Potassium Sorbate, Sodium Hydroxide, Citric Acid
Lengthening, Thickening, Darkening

2: Feminera Eyelash Serum

  • Description:

    This 100% vegan eyelash serum promises to promote healthy eyelash growth with its blend of natural ingredients.

  • Pros:
    • 100% vegan formula
    • Dermatologically tested
    • 60-day guarantee
  • Cons:
    • Key active ingredients appear low on the ingredient list
    • Only 3 ml of product per bottle
    • Relatively expensive considering the product volume
Why Choose Feminera Eyelash Serum

Feminera Eyelash Serum’s main active components for promoting hair growth are biotinol tripeptide-1 and myristoyl pentapeptide-17. These peptides are known for their potential benefits in helping stimulate hair growth and improving lash appearance.

The serum also includes ingredients like panthenol (pro-vitamin B5) for hydration, tocopherol (vitamin E) as an antioxidant, and plant extracts such as soybean germ, wheat germ, ginger root, and Scutellaria baicalensis root, which may offer additional nourishing benefits.

It’s worth noting that while the serum includes these beneficial ingredients, some of the plant extracts appear relatively low on the ingredient list. This might affect their concentration and efficacy in the overall formula.

Another consideration is the product volume. Each bottle of Feminera Eyelash Serum contains 3 ml of product, which is less than some other eyelash serums on the market (In comparison, the Scandinavian Biolabs serum offers better value, providing 5 ml of product at a slightly lower price point).

Ingredients:

aqua, glycerin, pentylene glycol, phenoxyethanol, propanediol, aginine, lactic acid, ethylhexyglycerin, *biotinol tripeptide-1, myristoyl pentapeptide-17, panthenol, tocopherol, glycine soja (soybean) germ extract,triticum vulgare (wheat) germ extract, gluconolactone, zingiber officinale root extract, scutellaria baicalensis root extract, sodium benzoate, potassium sorbate, calcium gluconate.

3: e.l.f. Enhancing Lash and Brow Serum

  • Description

    The e.l.f. Enhancing Lash and Brow Serum comes from the well-known and affordable beauty brand e.l.f. (Eyes Lips Face).

  • Pros:
    • Product from a well-known and trusted brand
    • Budget-friendly price point
  • Cons:
    • Limited ingredients specifically for hair growth
    • Castor oil, the main growth-promoting ingredient, is relatively low on the ingredient list

Why Choose e.l.f. Enhancing Lash and Brow Serum

The e.l.f. serum’s formula includes a couple of ingredients that may help with hair growth. These are ricinus communis (castor) seed oil, glycerin, and sodium hyaluronate.

Castor seed oil appears as the 8th ingredient on the list. It’s a popular natural remedy for boosting hair growth and thickness. 

Glycerin and sodium hyaluronate appear higher on the list. They’re excellent for adding moisture to the hair. While they don’t directly stimulate growth, they can help improve the overall health and appearance of lashes and brows by keeping them hydrated.

However, it’s worth noting that beyond these ingredients, the serum doesn’t seem to contain other ingredients specifically targeted at stimulating eyelash or eyebrow growth. The formula appears to focus more on moisturizing the hair rather than actively promoting growth.

“I use this daily, to every other day (being honest) and my lashes are long and healthy. Great product for price!” – Jessica (Amazon)

Ingredients:

Water (aqua), glycerin, polysorbate 20, hydroxyethylcellulose, sodium hyaluronate, larix europaea wood extract, camellia sinensis leaf extract, ricinus communis (castor) seed oil, panax ginseng root extract, disodium edta, sodium metabisulfite, glycine, sodium nitrate, zinc chloride, glyoxal, tromethamine, phenoxyethanol, caprylyl glycol, ethylhexylglycerin.

4: Bionoble Organic Castor Oil

  • Description:

    Bionoble offers a large bottle of pure, organic castor oil for those curious about its potential hair and lash growth benefits.

  • Pros:
    • Versatile product with multiple potential uses
    • Largest volume among the products in this list
    • Budget-friendly option for those wanting to try castor oil
  • Cons:
    • Limited scientific evidence specifically for eyelash and eyebrow growth
    • Contains only one ingredient, which may limit its efficacy compared to multi-ingredient serums
    • May be too heavy or greasy for some users
    • Requires careful application to avoid getting oil in the eyes
Why Choose Bionoble Organic Castor Oil

Bionoble’s product stands out for its simplicity – it’s just 100% organic castor oil. Nothing else.

This oil has become a social media darling thanks to its high ricinoleic acid content, which some believe boosts hair growth and health. It’s also packed with vitamin E and minerals that can help nourish your hair and scalp.

But while Bionoble’s castor oil is pure and potentially beneficial, it might not be your best bet if you’re after dramatic lash or brow growth. Its effectiveness relies solely on castor oil, which shows promise but hasn’t been as thoroughly studied for lash growth as ingredients in specialized serums.

“I use it on my lashes and already can see the difference.” – Diana Gherbi (Amazon)

Ingredients:

Ricinus Communis (Castor) Seed Oil

Why Some Top-Rated Eyelash Serums Are Not in This List

The short answer:

Many popular eyelash growth boosters contain prostaglandin or prostaglandin analogues.

While effective, these ingredients can have side effects. That’s why we’ve left them off our list.

Let’s get to know prostaglandins a bit more.

The eyelash serum industry kicked off when scientists found that prostaglandin analogues in glaucoma meds had a surprising side effect: longer lashes. This discovery led to a boom in lash-enhancing serums.

This discovery led to the development of eyelash serums specifically formulated to enhance lash length and thickness.

So you can see that several big-name lash serums use prostaglandin or its analogues.

While these products often get rave reviews for effectiveness, we’ve chosen to leave them off our list. We’re focusing on options that can boost your lashes without the risks that could potentially come with prostaglandin analogues.

Weigh the Pros and Cons Before You Buy

Your eyes are super sensitive. So, it’s best to avoid harsh treatments. Here’s what you should do:

  1. Research thoroughly: Whatever eyelash serum catches your eye, take the time to thoroughly research its ingredients.
