    We all wish we had longer, fuller lashes; why do you think we go for treatments like LVL Lashes, spend years looking for the best false eyelashes and make our way through the list of best mascara to try and find a formula that answers all of our prayers?! There is another option, perhaps the route less travelled: eyelash growth serums.

    You hear people talk about the wonder of these products – giving up their lash extensions completely – seemingly an impossible task for some – and crediting eyelash growth serums for their luscious lashes that flutter like butterfly wings. But if we’re going to add this little product into our routines we need to know exactly what eyelash growth serums do and how they work? And in order to understand how they work, you need to understand how your eyelashes work. To get to the bottom of this we spoke with Joanne Corcoran from RevitaLash – one of the original eyelash growth serum brands –  to find out more about our teeny tiny eye hairs.

    First things first, you need to know that your lashes have three stages of life – how fancy of them. Anagen – the growth phase, Catagen – the transition phase, and Telogen – the resting phase.

    Eyelash growth serums – Anagen phase

    ‘During the anagen phase, the lashes are actively growing,’ explains Corcoran. ‘It lasts between 30 and 45 days. and only about 40 percent of the upper lashes and 15 percent of the lower lashes are growing at any one time. Each lash will grow to a specific length and then stop.’ (This explains why we don’t have to have regular lash trims.)

    By this point the lashes reach the catagen phase and the hair follicle shrinks. ‘If an eyelash falls out during this phase, it won’t grow back right away because the follicle needs to complete the catagen phase before it can move on to the next one. This phase lasts between two and three weeks.’

    The final stage is the resting phase, which can last more than 100 days before the lash falls out and a new one begins to grow. Don’t panic though, they won’t fall out at the same time and leave you with nothing, as Corcoran explains, ‘because each individual lash is in its own phase of the growing cycle, it’s normal for a few lashes to fall out most days. It typically takes between four and eight weeks to fully replace an eyelash.’

    OK so now you get that – where do eyelash growth serums come in?

    How do eyelash growth serums work?

    According to Corcoran, ‘the ingredients are combined in specific proportions to create a formula that contributes to the improved attractiveness, appearance, and beauty of your natural eyelashes.’ These ingredients basically work together to condition and strengthen lashes so they are less likely to break or fall out, boost the lashes with vitamins that protect them from external aggressors and condition and add shine.

    How often should apply them?

    Each serum will have its own directions, but generally it’s once a day – either in the morning or just before bed. After around 12 weeks you should see a marked difference to your lashes.

    What happens if you stop using it?

    If you run out or just simply keep forgetting to apply your eyelash growth serum, then your lashes will return to normal.
