Already familiar with eyelash serums? The growth-boosting formulas are developed to double – even triple – the length of natural lashes with a few weeks of diligent use. If you’re curious as to how these super serums actually work in delivering results that leave your heart (and lashes) aflutter, you’ve come to the right place!

But first thing’s first: why add one of these miracle must-haves to your routine in the first place? From tugging a lil’ too hard with the make up remover to overusing false lashes, there’s a whole host of reasons to reach for eyelash care. Yes, a volumising mascara delivers thickness and length, but only to a certain degree – don’t you dream of having those perks without daily application? Plus, many also opt for lash serums due to lash loss and thanks to these nutrient-packed formulas, these serums can recondition lashes and stimulate hair growth so it’s like the loss never happened…

However, it’s worth noting that many come with claims of lengthy lashes in only a matter of weeks – but it’s only with consistent use for a long period of time, you’ll see results. Patience and consistency are key, so the sooner you get to work, the sooner you could be living your best lash life… Oh, and did we mention most lash serums can also be used on your brows to deliver the same results? Talk about a multi-tasking marvel…

THE SCIENCE

In short, these super serums work by supporting hairs in their growth phases – when applied regularly, these power-packed formulas encourage the hair to grow longer, and with darker pigment (sounds pretty dreamy, right?).

Most serums today are based around peptides (AKA short chains of amino acids which are the building blocks of protein). And, considering your lashes are comprised of around 80% keratin protein, it’s easy to see how a topical top-up can nourish, thicken and support fuller growth.

Many of the best lash serums also contain a supporting cast of nutrients and vitamins to condition lashes. First up? Biotin, which helps support in strengthening the hair fibres protein, while an infusion of panthenol works to maintain moisture levels and prevent breakage. Oh, and speaking of protein, you may know collagen works wonders for our skin, but it’s also great for lashes. Think: thick, voluminous lashes with a coating of long-lasting hydration…

So, now you know all the nitty-gritty behind these supercharged serums, it’s time to explore the trustworthy treatments that’ll have you falling in love at first blink
