The beauty market is flooded with various products that promise to make lashes longer and thicker, including a range of lash enhancers. But one question always arises, "Do lash serums actually work?" In this comprehensive guide, we will delve into what lash serums and enhancers are, how they work, as well as their overall safety.

What Are Lash Serums?

The science behind eyelash serums.

Eyelash serums typically contain potent ingredients that boost eyelash growth and fortify the lashes. Some of the prevalent ones include:

  • Peptides: These are short chains of amino acids that serve as the foundational blocks for proteins like keratin, which is crucial for lash health.

  • Biotin: A staple in many serums - Biotin fortifies the hair shaft, leading to reduced lash fall.

  • Hyaluronic acid: boasts incredible moisturising capabilities and keeps the lashes hydrated. Protects lashes from dryness, keeping them supple and resistant to breakage. Coats individual lashes and helps to keep them shiny and healthy.

  • Natural Extracts: Ingredients from naturally-sourced materials such as green tea, pumpkin seed and nettle extracts that nourish and hydrate the lashes.

It's worth noting that not all serums are the same. Some are specifically formulated for those with sensitive eyes that exclude certain ingredients to mitigate irritation.

Are eyelash serums really safe? What you need to know before using them

Are eyelash serums really safe? What you need to know before you use it

The use of eyelash serums is generally safe if you follow the product instructions and guidelines. However, it is important to understand a few key points to ensure safe use.

General points for effective serum use

1 Duration of use

Lash Serums should be used continuously for 6-8 weeks to see gradual changes; after 8 weeks, some products recommend using the serum once every 2 days as maintenance once the effects have been felt.

2 Frequency of use

Follow the directions for use in the instructions and avoid excessive use.

Most products are either a twice-daily type, morning and evening, or a once-daily type before bed.

3 Professional tips on Lash Serum use

  • Correct usage is very important for safety. Wash your hands and ensure they are clean before using the product.

  • The brush supplied with the product is in direct contact with their skin and should be used in accordance with the manufacturer's recommended expiry date after opening.

  • Using too much at once or applying the lash serum more than the recommended number of times will not change the effect of the product. Instead, over-specification can cause unnecessary irritation to the eyes and skin, which may lead to unwanted side effects such as irritation.

  • As with any other beauty product, results may vary from person to person.

Are you taking precautions against allergies?

To avoid potential allergic reactions such as, "I used it and had an allergic reaction..." we recommend conducting a patch test before use.

Especially for products that claim to rapidly increase eyelash length, there is a high likelihood they contain prostaglandin analogues. Before using, apply a small amount on the back of your hand or the inside of your arm and observe the area for 24 hours.

If you experience any redness or itching, discontinue use immediately.

Comparing Lash Serums

comparing Lash serum

There's a diverse range of eyelash serums, there are three main categories:

1. Prostaglandin-based products (lengthening):

Products that primarily promote eyelash growth and lengthening.

2. Moisturising products:

Keeps lashes healthy by providing moisture. Usually mainly contains hyaluronic acid.

3. Density-enhancing products:

Focuses on lash thickness and density without much lengthening. Usually contains ingredients such as peptides.

Human stem cells have also become a topic of interest recently. Additionally, there are multifunctional products that adequately cover multiple categories at once, including organic and sensitive skin formulations, and those that aim to lengthen lashes, increase density, and moisturise. The variety of eyelash serums available is quite diverse.

*Each category has its own specific advantages and disadvantages, so it is important to choose according to your needs.

These are the main types found on the market and individual products may cover more than one category. New categories may also emerge as new technologies and ingredients are developed.

What kind of lash serum do lash artists look for?

What kind of lash serum do lash artists look for?

Lash artists likely seek lash serums that create an easy-to-work-with base for their treatments, wouldn’t you agree?

When performing a lash lift or applying lash extensions, it is challenging to achieve a beautiful result unless the client's natural lashes are thick and fairly numerous.

Some lash serums may cause the lashes to grow excessively long and thin, while others may show minimal effects. As a result, it's quite rare to find clients with naturally high-potential lashes that meet the ideal standards of lash artists.

Moreover, clients may not be aware of the condition of their own eyelashes, so they might not realise how hard lash artists are working to meet their expectations. Lash artists are diligently applying treatments to thin eyelashes, trying their best to fulfill client wishes.

Wouldn't it be great to have a lash serum that not only moderately increases the length of the lashes but also enhances their thickness, resilience, and density, rather than just focusing on length?

Wouldn't your treatments become easier if the eyelashes didn't just grow longer, but also didn't become unusually thin or prone to developing a curl or breaking?

Moreover, if the lashes are thick and robust at the core, the retention of a lash lift improves, and for extensions, the increased surface area for the glue naturally enhances the retention.

The eyelash serum that active lash artists have been waiting for is finally here!

Are Lash Serums Lash Extension Friendly?


For eyelash extensions to attach properly, it is vital that your eyelashes are healthy. Healthy eyelashes are supple and less likely to break. You’ll find that our serums contain many moisturising ingredients.

It is said that well-hydrated lashes are more resistant to extension fall out than dry lashes. Not only does this increase the longevity of the extension glue being firmly attached to the lashes, but it may also strengthen the overall retention of the extensions.

Expected Results and Duration of Use

Consistent use for 6-8 weeks generally results in clearly better outcomes. However, results may vary from individual to individual. Please refer to the product instructions for use as each product has its own specific instructions.

Why Lash Serums are Worth the Investment

Eyelash serums are an effective beauty product for many people. Especially for those with naturally short or thin eyelashes, lash serums can make a big difference (*results vary depending on the aforementioned categories).

However, the key to getting the most out of them is choosing the right product, using it correctly and continuing to use it. There are many options on the market, so choose the product that best suits your needs and budget.

If you are looking for a more permanent solution, lash serums are an effective and safe choice. Their unique combination of ingredients not only promotes the growth of your own eyelashes but also maintains their natural aesthetic appeal. Lash serums are a valuable addition to your beauty routine.
