Everything You Need To Know About Lash Serums

If you want to give your lashes a boost but falsies aren’t your thing, it’s time to make room in your beauty bag for an eyelash serum. Promising longer, thicker, fuller lashes – without even adding mascara – eyelash serums can work wonders at boosting that fluttery lash look. But do they really work and which formula is best? We’ve done the hard work so you don’t have to…

How do eyelash serums work?

Eyelashes, much like the hair on your head, are made up of protein and amino acids. For long, healthy luscious lashes, you’ll want to strengthen and nourish the condition of your lashes – which is where a lash serum can come in.

Eyelash serums work in a couple of different ways. Some formulas contain specific growth-enhancing ingredients, which are designed to stimulate lash growth. Whereas others contain ingredients that nourish and help to repair lashes, allowing them to naturally grow longer and stronger, enhancing the appearance and overall condition of the lashes.

What are the ingredients to look out for in eyelash serum formulas?

Different eyelash serums often contain many similar ingredients, but it’s always good to know which are the stand-out ingredients to look out for within the inkey list.

If you’ve ever taken hair, skin and nail supplements – you’ll have probably heard of biotin. And it’s a common ingredient within eyelash serums, too. Biotin is a key B-vitamin that helps to strengthen keratin – the main protein that makes up your hair and lashes.

Another common ingredient within lash serums is castor oil. This nourishing ingredient helps to moisturise lashes, helping them appear thicker and fuller. Beware of DIY castor oil remedies though. Lash serums go through rigorous testing to make sure they’re safe to use and delivered in a measured way. Applying unregulated, neat oil close to your eyes is never a good idea. 

Lash serums are commonly packed with peptides – which are believed to stimulate hair growth at the follicle. They can also increase the flexibility of the hair, which in turn can help reduce any breakage of the lashes, helping them grow longer and stronger.

How to use an eyelash serum?

The best way to introduce an eyelash serum into your routine is by making it the final step of your skincare routine. Apply each morning and evening on clean, dry lashes. Some formulas have a mascara-like wand, making application super simple, whereas others have a fine brush, allowing you to paint the formula onto the lash line.

Are eyelash serums safe?

When used correctly (always read the instructions label!) yes, lash serums are safe and easy to use. As with any cosmetic product, some people might have allergies, so if you experience any tingling, itching or redness – stop using the serum and consult your doctor.
