Who doesn’t love the look of long, healthy lashes? Beautiful natural lashes not only enhance your look, they also help your lash extensions and lash lifts look their best. If you’re worried about damage, or your lashes are looking a little sparse, learning how to apply lash serum correctly could be just what you need.d.
How to Apply Lash Serum Correctly

You may already own a lash serum but aren’t quite sure you’re using it the right way. It’s common to simply apply it without really knowing the correct method. Here, we’ll walk through how to get the most out of your serum.
What Is Lash Serum?

Lash serums generally fall into two categories.
| Type | What It Does |
|---|---|
| Growth-support serum | Helps strengthen weakened lashes and supports thicker, fuller-looking growth |
| Moisturising serum | Protects lashes from dryness and adds shine and hydration |
Lash serums also come in a few different applicator types.
- Brush type – similar to a mascara wand
- Pen type – similar to an eyeliner
- Tip type – similar to a gloss applicator
Since you’ll be using it daily, it’s worth choosing one that’s simple and easy to apply.
Who Should Use Lash Serum?

1. Those With Lash Extensions
Lash extensions add volume and length by attaching artificial lashes to your natural ones, but this can put some stress on your natural lashes. Using a growth-support serum regularly can help strengthen your lashes and minimise damage.
Tip: choosing the right length and thickness of extensions for your natural lashes also helps avoid unnecessary strain.
2. Those Who Use an Eyelash Curler Daily
An eyelash curler can cause some damage due to the pressure applied when curling. Strong pressure can lead to breakage or lash loss, so it’s worth caring for your lashes with a growth-support serum.
3. Those With Lash Lifts
A lash lift causes less stress on your lashes than an eyelash curler, but there’s still some impact. A moisturising coating serum is recommended to add hydration and protection, and combining it with a growth-support serum can also help.

Before You Apply Lash Serum

If you’re not seeing the results you’d hoped for, it’s worth checking these points first.
1. Timing of application
- Growth-support serums:
apply to clean lashes before your night-time skincare routine. Applying after products like lotions or creams can create a barrier that reduces absorption. - Moisturising serums:
apply before your skincare routine, morning or night. Used in the morning, it can also work as a mascara primer, helping protect your lashes from daytime dryness and UV exposure.
2. Cleanse the eye area thoroughly
Leftover makeup can prevent the serum from absorbing properly. Gently remove eye makeup with a suitable cleanser first.
3. Massage the eye area
Good circulation around the eyes helps deliver nutrients to the hair follicles, supporting healthier lash growth.
Method: warm a towel and place it over your eyes, then gently tap your upper and lower eyelids to encourage blood flow.
Where and How to Apply Lash Serum

- Growth-support serums: apply along the lash line, as if drawing on eyeliner.
- Moisturising serums: apply from root to tip with an upward brushing motion. Dividing your lashes into three sections (inner corner, centre, outer corner) helps you apply it evenly.
Things to Keep in Mind
It might be tempting to apply a generous amount to see faster results, but it’s important to stick to the recommended dosage.
Overuse, particularly of growth-support serums, can lead to:
- Irritated eyelids
- Redness and itching
- Increased discharge
As a general rule, growth-support serums only need a single pass along the lash line, similar to applying eyeliner. Avoid layering multiple coats, as this increases the risk of irritation or overuse.
Tip: always follow the product’s instructions and recommended dosage.
Where to Buy Lash Serum

Lash serums are widely available at drugstores and online these days. That said, if you’re after the best results, salon-exclusive products are worth prioritising.
ADVANCED.byK (Growth-Support Type)
A hormone-free, alcohol-free serum that supports healthy lash growth. Designed to fit easily into your daily routine.
Style & Coat (Moisturising, Coating Type)
A deeply moisturising coating serum for delicate, post-lash lift lashes. As well as hydrating, it helps keep your lash flow in place and supports how long your curl lasts, and since it’s absorbed rather than rinsed off, there’s no need to wash it out.
Frequently Asked Questions About Lash Serums

Q: Can lash serums cause pigmentation?
Most lash serums are unlikely to cause pigmentation. That said, certain medicated lash growth products containing ingredients like bimatoprost may carry this risk. Bimatoprost is a pharmaceutical ingredient used in some glaucoma treatments and lash growth products.
Note: using products with strong active ingredients excessively or incorrectly can also lead to pigmentation. Always check the ingredient list before purchasing, and follow the recommended usage.
Q: Do I need to use lash serum every day?
Yes, daily use gives the best results. Consistent application helps you notice improvements over time.
Q: How long does it take to see results?
This varies from person to person, but you can generally expect to notice initial changes like added moisture and strength within 6 to 8 weeks, with fuller growth-support results becoming more noticeable after around 3 months of consistent use.
