From peptide-rich formulas to nourishing plant oils
@christinanadin

Long, fluttery lashes never go out of style—but the way we achieve them has certainly evolved. While lash extensions and tints still have their place, more and more are turning to eyelash serums as a low-maintenance alternative to boost natural length and volume. And it’s easy to see why: when used consistently, a quality lash serum can help fortify fragile lashes, reduce fallout, and even give the illusion of added fullness.

But not all formulas are created equal. From gentle, prostaglandin-free options to clinically backed growth enhancers, the market is crowded—and navigating the claims can be overwhelming. So, we did the work for you. After combing through bestsellers, reviewing ingredient lists, and considering expert insight, we’ve curated the most effective eyelash serums available in Australia right now. Whether you’re after a subtle boost or dramatic results, these are the formulas worth your time (and money).

Ingredients To Look For

Peptides
Peptides are short chains of amino acids that help stimulate the production of keratin, the protein that makes up your lashes. By strengthening the hair structure, peptides can improve lash resilience and reduce breakage. They also support the natural growth cycle for fuller, healthier lashes over time.

Biotin (Vitamin B7)
Biotin is essential for healthy hair growth and helps reinforce the structure of keratin. It can improve the thickness and strength of each lash, making them less likely to fall out prematurely. While it won’t create new growth on its own, it plays a vital role in maintaining lash density.

Panthenol (Vitamin B5)
A deeply hydrating ingredient, panthenol helps retain moisture within the lash shaft. It smooths and conditions lashes, making them appear shinier and more flexible. This helps prevent brittleness and breakage from everyday wear and makeup removal.

Hyaluronic Acid
Known for its ability to hold up to 1,000 times its weight in water, hyaluronic acid keeps lashes hydrated and plump. Well-hydrated lashes are more elastic and less prone to snapping. It’s particularly beneficial for restoring moisture to dry or damaged lashes.

Natural Plant Extracts
Ingredients like castor oil and green tea extract are rich in nutrients and antioxidants. Castor oil has long been praised for its ability to nourish follicles and improve lash texture, while green tea helps soothe the lash line and support hair growth. These botanicals condition the lashes while protecting against environmental damage.

What Are Prostaglandins, and Why Are They Regulated in Australia?

Prostaglandins are lipid compounds originally used in glaucoma medications. When repurposed in lash serums, they can encourage longer, darker lashes — but they may also cause side effects like eyelid darkening, fat loss around the eye, eye irritation, or even eye colour changes.

In Australia, lash serums containing synthetic prostaglandin analogues such as isopropyl cloprostenate have been removed from shelves by the TGA. Brands using these compounds must comply with medical regulations or cease distribution. They can only be obtained with a prescription. 

If you’re unsure, always check the ingredient list or choose a prostaglandin-free serum to play it safe.

Frequently Asked Questions

How long do eyelash serums take to work?

Most serums show results after 4–8 weeks, with full results appearing around the 12-week mark. Consistency is key.

Do lash serums have side effects?

Yes, some lash serums can cause side effects, particularly those that contain prostaglandin analogues. Potential reactions may include eye redness, itching, darkening of the eyelid skin, or even changes in eye colour with long-term use. Prostaglandin-free formulas tend to be gentler, but it’s always best to patch test first and discontinue use if irritation occurs.

Can you use lash growth serums with eyelash extensions?

Yes, many lash growth serums can be used with eyelash extensions, but it’s important to choose an oil-free formula to avoid weakening the adhesive. Look for serums that are specifically labelled as extension-safe and apply them only to the lash line, not directly on the extensions. As always, check with your lash technician before introducing new products to your routine.
