Who doesn’t dream of long, thick, curving lashes that make your eyes sparkle? Lash serums are the secret weapon of many to achieve just that. There is a huge amount of serums on the market and they all promise the same thing. The search for the perfect lash serum can quickly feel overwhelming – the classic selection paradox.
But which eyelash serum does what it promises – and how can you tell? That’s exactly what we’re going to look at today, because we’re taking a closer look at the topic of ‘eyelash serums’.
What you should know about eyelash serums
While mascara and false eyelashes offer temporary solutions, eyelash serums promise permanent results. This is why they have become a popular beauty trend in recent years. But how do these serums actually work?
Eyelash serums are specially formulated products that aim to promote the growth and density of eyelashes. They contain a blend of ingredients that support the natural growth cycle of eyelashes. More specifically, they extend the anagen phase (growth phase), which leads to longer hairs and shorten the telogen phase (resting phase), which in turn leads to thicker lashes.
However, the effectiveness of an eyelash serum depends on its ingredients. Here are some of the most common and important ingredients to consider when choosing a serum:
Biotin:
- Supports keratin production, a protein that is an essential component of eyelashes
- Can help to improve the strength and density of eyelashes
- Promotes the general growth and health of eyelashes
Peptides:
- Short amino acid chains that support the health of hair follicles
- Promotes the growth and regeneration of eyelashes
- Strengthen the structure and strength of eyelashes by stimulating keratin and collagen production
Hyaluronic acid:
- Excellent ability to bind and retain moisture
- Keeps lashes supple and hydrated
- Nourishes and strengthens the lashes, protecting them from damage and breakage
Panthenol:
- Penetrates deep into the hair structure and strengthens the lashes from the inside out
- Gives the lashes shine and suppleness
- Supports regeneration and protects against environmental damage
Plant extracts:
- Green tea: Provides antioxidant properties that protect the eyelashes from free radicals
- Camomile: Has an anti-inflammatory and soothing effect on the skin around the eyelashes
- Ginseng: Promotes blood circulation and supports eyelash growth
Collagen:
- A protein that improves the structure and elasticity of eyelashes
- Helps to make eyelashes thicker and stronger
- Supports the regeneration and growth of eyelashes
Arginine:
- An amino acid that improves blood flow to the hair follicles
- Promotes the growth and strength of eyelashes
- Supports the regeneration and health of eyelashes

What you should look out for when buying an eyelash serum

In addition to the ingredients, there are also other criteria that can help you find a high-quality and effective product. Even if it takes time, with a little research and attention to detail you can avoid making the wrong purchase. After all, who wants to test a bunch of eyelash serums before finally finding the right one for them?
If you pay attention to the following criteria when making your choice, you can’t really go wrong:
Safety and side effects:
When comparing the ingredients of a serum, you should not only make sure that it contains as many substances as possible that promote the growth and health of your eyelashes. You should also make sure to check for possible allergens or irritating substances.
Also make sure that the serum has been dermatologically tested and has no harmful side effects. Reputable brands are generally transparent about their ingredients and the results of such tests.
Effectiveness
Customer reviews are often helpful to check whether a serum can keep the manufacturer’s promises. You can quickly get an impression of the effect and tolerability of a product from testimonials. As the effect of cosmetic products is often very individual, you should always make sure to look for reviews from people who are as similar to you as possible, e.g. in age or skin type.
Nevertheless, you should always take these reviews with a grain of salt. Unfortunately, many platforms have a problem with fake reviews. Reviews that describe extremely positive or negative experiences without providing specific details can be a sign of this. Real reviews usually write about a mixture of positive and negative experiences with a product.
Application and user-friendliness
Of course, it is also important how easy a product is to use. Because let’s be honest – if you have to struggle with the packaging before applying the product, you’ll quickly lose interest in it. With eyelash serums, however, it is essential to apply them regularly. So choose a product that you can easily incorporate into your routine without any extra steps or time.
Long-term effect and patience
The results of eyelash serums often only become apparent after a few weeks of use. Be prepared to be patient and use the product regularly to get the best results. Short-term miracles should be viewed skeptically, as effective eyelash serums need time to develop their full effect.
Safe and effective: using eyelash serums
Now you know everything you need to find the perfect serum. Nevertheless, you should bear in mind that an eyelash serum can only work as well as it is applied. But what should you actually look out for when using it?
With these step-by-step instructions, you will know all the tips and tricks you need to use your eyelash serum correctly:
1st patch test:
To be on the safe side, you should test each product to see if you are allergic to the ingredients. To do this, apply a little of the product to an inconspicuous area of skin before the first application and wait 24 hours to see if you notice a reaction.
The skin on the inside of the elbow is particularly suitable for eyelash serums, as it is similarly thin and sensitive as the eye.
2nd preparation:
In order for the serum to do its job, it must of course be able to be absorbed into the skin. However, make-up, sunscreen or creams prevent this. It is therefore important to always cleanse your eye area thoroughly and dry it completely before applying the eyelash serum. Excess moisture also interferes with the effectiveness of serums!
3rd application:
It is best to always follow the manufacturer’s instructions for application. As a rule, lash serums are applied once a day in a thin layer directly to the lash line, just like liquid eyeliner.
You should make sure that the serum does not get into your eyes. With some products, you may need to wipe the applicator on the edge of the bottle to remove excess serum. If you do accidentally get some in your eye, you should rinse it out thoroughly with clean water.
Regularity and patience
Most eyelash serums should be used daily. Most brands also advertise after how many weeks the first results are visible. The emphasis here is clearly on the fact that these are only the first results. So before you can judge the final result, you have to be patient. The best results are usually achieved after around 3 months.
Durability:
Do you still have eyeshadow lying around that is older than you’d like to admit? Especially with expensive products, many people tend to use them as sparingly as possible so that they last longer. It is often also safe to exceed the best-before date.
However, when it comes to liquids, you should urgently get out of the habit. Unfortunately, the moist environment is the perfect place for bacteria to grow. It’s better not to take the risk, especially on your eyes. Many expired products can not only cause undesirable reactions, they also simply lose their effectiveness.
Therefore, always check the expiration date on your eyelash serum. The symbol indicating how many months a product can be used after opening can usually be found on the product itself or on the packaging. To make sure you don’t forget when it’s time to replace your eyelash serum, you can easily set a reminder in your calendar on your smartphone.
Do not use excessively:
A lot helps a lot – right? This does not apply to eyelash serums. If you apply too much serum at once, it can quickly end up in the eye. This in turn quickly leads to irritation. Applying an eyelash serum several times a day will not give you faster results either, but will only irritate your sensitive eye area unnecessarily.
Storage:
Some ingredients are sensitive to light and heat. However, if you store your eyelash serum in a dry, cool place instead of in direct sunlight, you no longer need to worry about this.
Also make sure that the applicator only comes into contact with your previously cleansed skin and that the serum is tightly closed after each use. This way you avoid unnecessary contamination.
Conclusion
Eyelash serums are a great addition to your beauty routine if you want long, thick lashes. With the information and tips above, you’ll be well prepared for your search for the best serum. And with just a little patience, you can fulfill your dream of beautiful, healthy eyelashes.
