Quick answer
When you stop using a lash serum, your lashes gradually return to their pre-treatment length and thickness over a few months, as each lash sheds naturally and is replaced by one that grows back at your natural length. To keep your longer, fuller lashes, keep using your serum: once you're happy with your results, Spectaculash only needs 3 to 4 applications a week.
You've grown the longest, fullest lashes you've had in years. Friends are asking if they're extensions, and you've given up on mascara most days. So what happens if you stop using your lash serum? When you stop using a lash serum, your lashes gradually return to their pre-treatment length and thickness. It doesn't happen overnight: the lashes you have now stay until they shed naturally, and the new ones that replace them grow back at your natural length over the next few months. So if you want to keep your luscious lashes, keep using your serum. Once you're happy with your results, Spectaculash only needs 3 to 4 applications a week to keep them looking long, full and thick.
Here's exactly what happens when you stop, why it happens, and the easy way to keep the lashes you love.
What happens when you stop using a lash serum?
Every lash follows its own growth cycle: it grows, rests, falls out and is replaced by a new one. A good lash serum works with that cycle, helping each new lash grow in longer, fuller and stronger. Spectaculash does this with clinically studied Myristoyl Pentapeptide-17, hyaluronic acid and pumpkin seed extract, which helps lashes stay in their growth phase for longer.
When you stop, the lashes you already have don't suddenly change. They stay put until they naturally shed. It's the new lashes that grow in afterwards, without the serum's support, that come back closer to your natural length and fullness. Because every lash is at a different stage, the change is gradual and happens over a few months, not days.

What changes when you stop
Lashes slowly return to their natural length
As your serum-boosted lashes shed naturally, the new ones grow back at your own natural length. Most people notice the difference gradually over a few months.
Fullness fades gradually
A fuller lash line comes from more lashes growing at once. Without the serum's support, your lash line slowly settles back to how it was before.
No sudden fall-out
You might spot a few lashes on your pillow, but that's normal everyday shedding, the same as always. Stopping doesn't make your lashes fall out.
Your results go with it
Spectaculash supports every new lash while you use it. Stop, and over a few months your lashes look just as they did before you started. Keep going, and you keep your results.
Myth or fact?
Things people worry about
Myth"My lashes will fall out if I stop."
Fact: No. Your lashes stay put until they shed naturally, just as they always have. Stopping doesn't cause extra fall-out.
Myth"My lashes will end up worse than before."
Fact: No. They gradually return to their natural length and fullness, not shorter or thinner than before you started.
Myth"I'll have to use it every night forever."
Fact: No. Once you love your lashes, 3 to 4 applications a week keeps them looking their best, and you can stop at any time.
Love your lashes?Keep using your serum.
Will my lashes go back to how they were before?
Yes. Over the next few months, your lashes return to their pre-treatment length and thickness, just as they were before you started. That's why the secret to luscious lashes is simple: keep using your serum. Once you love your lashes, just 3 to 4 applications of Spectaculash a week keeps them long, full and thick. And if you have stopped, it's never too late: start again, and with consistent nightly use your lashes can look longer, fuller and thicker in as little as 60 days.
How to keep your longer lashes
Switch to maintenance mode. Once you're happy with your lashes, you don't need to apply Spectaculash every night. Just 3 to 4 applications a week keeps them looking their best.
Be gentle. Rubbing your eyes and scrubbing off waterproof mascara can pull out lashes faster than they grow. Our dual-sided face cloths remove even waterproof mascara with just water.
Make it a habit. Keep Spectaculash next to your toothbrush or with your night-time skincare, so you never forget.

Thinking of switching lash serums?
If you've stopped because your current serum didn't work for you, or you didn't like what was in it, here's what to look for:
- Hormone-free, with no prostaglandins. Many lash serums use prostaglandin analogues. Spectaculash doesn't, and it's suitable for sensitive eyes, contact lenses and lash extensions.
- Ingredients that work as a team. Clinically studied Myristoyl Pentapeptide-17, hyaluronic acid and pumpkin seed extract, alongside phyto-collagen, sphingolipids and arginine.
- Proof from real customers. Award-winning, featured in Vogue, Tatler and Woman's Weekly, and rated 4.5 out of 5 from over 300 reviews: "Wasn't sure whether to believe this could work but it definitely does. Got 3 others using it now!"
- A promise you can trust. If you use Spectaculash every day for 60 days and don't see noticeable growth, we'll give you your money back.
A 3ml bottle of Spectaculash is £24.99 and covers the full 60-day programme. Want fuller brows too? Our Lash and Brow Growth Serum Set gives you both for £44.99.
The science, simplyHow Spectaculash works in your skin
Lashes grow in cycles. Each lash goes through a growth phase, a short transition phase and a resting phase before it falls out and is replaced. Every lash is at a different stage, which is why you only ever lose a few at a time.
How a lash serum helps. Spectaculash supports new lashes as they grow, with Myristoyl Pentapeptide-17 for longer, fuller, thicker-looking lashes and pumpkin seed extract to help lashes stay in their growth phase for longer.
Why results fade gradually when you stop. The lashes you already have stay until they shed naturally. Only the new lashes that grow in afterwards return to your natural length, so the change happens slowly, over a few months.
