You've invested in a lash serum — now let's make sure you actually get the results. Believe it or not, how you apply your serum makes a huge difference, and a few tiny mistakes are the reason some people give up before they see anything. Here's exactly how to apply lash serum the right way, plus the slip-ups to avoid.
How to apply lash serum: step by step
- Start with a clean, dry, makeup-free lash line. Remove all eye makeup and any oil-based products, and make sure the area is fully dry. Serum applied over makeup or moisturiser simply can't absorb.
- One dip is enough for both eyes. There's plenty of product on the applicator — you don't need to re-dip.
- Swipe along your upper lash line only, like you're applying a thin line of eyeliner, from the inner corner out. Don't apply to your lower lashes — it just increases the chance of serum getting into your eyes.
- Apply at night. You can use it morning or evening, but nighttime is best: your serum gets to work undisturbed with no makeup or rubbing on top.
- Let it dry for a few minutes before any other products or going to sleep.
That's it — a five-second step that fits into your existing routine.
The most common lash serum mistakes (and how to avoid them)
- Over-applying or double-dipping. More serum won't speed things up — it just runs out faster and can increase the chance of irritation. One thin swipe is all you need.
- Applying to the lower lash line. Stick to the upper lash line only to keep the product away from your eyes.
- Applying over makeup or damp skin. The lash line must be clean and dry, or the serum can't absorb properly.
- Being inconsistent. Skipping days is the number-one reason people don't see results. Lash serums work with your natural lash cycle, so daily use is what delivers.
- Quitting too soon. Most people see first changes around 4–6 weeks and full results by 12. The magic usually happens right after the point most people give up.
How long until you see results?
With consistent nightly use, most babes notice longer, fuller-looking lashes within 4–6 weeks, with full results around 12 weeks — because that's how long it takes for your natural lash cycle to turn over. (We break this down properly in our guide on how long lash serum takes to work.)
Keeping your results
Once you've reached your lash goals, you don't need to stop — just drop down to applying 2–3 times a week to maintain them. One bottle of our serum typically lasts 2–3 months, so upkeep is easy and affordable.
The takeaway
Applying lash serum correctly is simple: clean, dry lash line, one swipe up top, every night, and stick with it. Nail those basics and you give your lashes the best possible chance to grow.
