How Do Lash Serums Really Work?

I know what you’re thinking - Do lash serums really work? The truth is, they do work really well to support healthy lashes, whether that’s from the root or providing essential nutrients that boost lash growth. For anyone who wants to give their lashes a fluttery boost or recover from accidental eyelash damage, an eye serum is definitely a product that can help! Here’s what goes into a lash serum to make them work and how long you can wait before seeing real results. 


What are lash serums?

Lash growth serums are created with formulas that enhance lash growth, whether that’s with the use of natural ingredients, plant oils, or prostaglandins. There’s a wide variety of ingredients that can come together to support your eyelash growth for lush, long eyelashes!

Eyelash Growth Serum


"If I'm honest I was kind of skeptical about lash serums because ones I've used in the past haven't done anything, but I've been fully blown away by UKLASH! My lashes were really brittle and fell out so easily, so I constantly had huge gaps in them. It made me so self conscious of it but now I have gorgeous lashes. Thank you so much!" - Beth

How do lash serums work?

Lash serum usually has one of or both of these effects on eyelashes: conditioning eyelashes or stimulating hair growth.

Lash serums that focus on conditioning lashes can help make lashes appear longer. By conditioning eyelashes from root to tip with natural oils and other soothing ingredients, eyelashes are less likely to become brittle and prone to breaking off - a common complaint that results in lashes looking shorter than they actually are. Conditioning lash serums give your eyelashes the best chance to grow as long as possible before starting the lash cycle again.

Growth-stimulating lash serums take effect at the root of your lash, delivering ingredients that speed up hair growth so your eyelashes grow faster in the same period of time compared to eyelashes that haven’t had the same ingredients. One of the most common ways that eyelash serums boost lash growth is by extending one part of the lash growth cycle - the telogen phase.

The telogen is also called the growth phase, and by keeping your eyelash follicles in this phase for longer, a lash serum ensures that your lashes are able to grow as long and fluttery as possible.

What ingredients are in lash UKLASH serum?

All of the ingredients in UKLASH serum are specifically chosen for their lash-nourishing abilities - let’s go over a few now.

  1. Swertia Japonica: A natural hair-growth remedy originating from Japan - Swertia Japonica Extract is commonly used to help slow down the effects of alopecia (aka baldness) by improving circulation, resulting in healthy hair growth. 
  2. Pentapeptide-17: Our eyelashes are made of a protein called keratin - when the keratin itself is damaged, that's when our lashes look brittle and sparse. Peptides and amino acids are considered the very building blocks of protein, so including them in an eyelash serum encourages thicker eyelashes by repairing any damage and preventing it from occurring in the first place.
  3. Panthenol: Panthenol is an incredibly powerful moisturiser for both skin and hair and is a key component to growing lush, healthy eyelashes. Lashes can be easily dried out from the environment or even waterproof mascaras, so using panthenol keeps them moisturised and supple.
  4. Pumpkin Seed Extract: Pumpkin seed extract is an incredibly potent lash-boosting ingredient. Naturally rich in fatty acids, zinc, and phytosterols, it intensely nourishes lashes and prevents them from falling out as easily. It encourages the lash to stay in the anagen phase, aka the growth phase, for longer, boosting length and delaying the natural hair fall cycle.

How Long Do Lash Serums Take to Work?

As a general rule of thumb, it can take at least 12 weeks to see meaningful results from any lash serum - and while that sounds like a long time, it makes perfect sense when you think of how long the lash lifecycle can take. 12 weeks gives your eyelashes enough time to make the most of any eyelash serum that you use, whether it simply conditions your lashes from root to end or boosts your lash growth by holding your lashes in the growth part of the cycle for longer.

How to get the best results?

In order to get the best results from your eyelash serum, try a couple of these pointers to follow. 

The ideal time of day to use an eyelash serum is as part of your nightly beauty ritual. This ensures that the lash serum has plenty of time to absorb into your lashes, completely undisturbed. 

It’s also perfect for ensuring your bottom lashes get enough serum too! There’s a small amount of transfer between your upper and lower lashes, ensuring your bottom lashes get a nightly dose of lash serum, all while you’re sleeping.

While it sounds like applying lash serum multiple times a day would be better, there’s no evidence to suggest that more applications are better for growing lashes. There’s only so much lash serum you can apply at once! Plus - you’ll just run out of lash serum before you need to! Instead, keeping the application consistent (every night for at least 4 weeks) is ideal for supporting lash growth.

Can I use lash serums on my brows?

Using lash serums on eyebrows is generally considered safe, but it's essential to check product labels and instructions. 

Many lash serums contain ingredients beneficial for brow hair growth, such as biotin and peptides. However, for targeted eyebrow care, it makes more sense to use a dedicated product like UKBROW - a brow serum designed specifically for eyebrows. 

This ensures that the formulation is optimised for brow hair, providing the most effective and safe results.

Always follow recommended application guidelines and perform a patch test before regular use to maintain healthy and beautiful eyebrows.

Are Lash Serums Safe to Use?

When used properly, lash serums are 100% safe to use. They’re formulated to be safe and non-irritation for both your eyes and the delicate eye area. Always follow eyelash serum instructions to ensure that you’re getting the most out of your eye serum - this usually involves applying the lash serum once a day at night, just before bed. It’s also recommended to avoid applying eyelash serum while you have contact lenses in - wait to take them out before applying your nightly eyelash serum for the best lash results!

Potential risks and side effects

While lash serums aim to enhance lash appearance, users should be aware of potential risks. Some individuals may experience irritation, redness, or itching, especially if sensitive to the serum's ingredients. 

To mitigate these risks, it's crucial to strictly follow product instructions, perform patch tests, and avoid contact with the eyes. Consultation with a healthcare professional is advised, especially for those with pre-existing eye conditions or allergies. 

Prioritise safety and discontinue use if adverse reactions occur, seeking medical guidance for a tailored approach.
