Safety confirmed in tests





Eyelashes live for about 3 to 6 months, and then fall out. The first 30 days constitute the eyelash growth phase, followed by so-called stationary phase during which the eyelashes do not grow any more.



Why should the serum be used only once daily, in the evening?

The serum´s formula contains a complex of active substances that are now considered as one of the most effective compounds for hair strengthening. Therefore, there is no need for more frequent application of the serum. We recommend using the serum in the evening with your eyes closed to ensure safer use.

Can the serum be used together with eyebrow and eyelash dye?

Yes, they can be used together.

What products does the L4L line contain?

How long does one serum last?

The serum suffices for the entire recommended period of the therapy, namely 4 months if used once daily / one application of the serum.


Why is the L4L serum better than its competitors?

Long4Lases serum is present on the market since 2013 what gives a great experience to the brand. What is more, the number of the customers who decided to boost their lashes with L4L products grow year by year and the fame of the serum expands worldwide. This is the best recommendation for our product. To stay precise, L4L FX5 serum is based on the latest achievements in global cosmetology – active peptide complex. Besides this, it’s uniqueness benefits from addition of precious oils which are present in the formulataion.

How does the serum work?

The serum works throughout the eyelashes/eyebrows growth cycle. Therefore, it can effectively nourish them by improving their condition and appearance, and you can enjoy a spectacular frame for your eyes!

Why do the lashes fall out (at different times) after using the serum?

The standard eyelash growth cycle lasts between 3 and 6 months. During this cycle, the eyelashes go through three stages: intensive growth stage, transition stage and resting stage. The eyelashes only grow in the first stage and they fall out at the end of the entire cycle. Our conditioner does not change this natural process. What it does is that it acts actively during the entire eyelash growth cycle – it stimulates the growth of natural eyelashes and then prolongs their life. However, in some cases, the highly stimulated growth cycle of the eyelashes may make the “old eyelashes” fall out earlier in favour of the new ones (longer and thickened) after the first 2-3 weeks of using the conditioner. There is nothing to worry about as the process is only temporary and it indicates an effective start to the product’s action. Following therapy, the eyelash growth cycle remains intact. The eyelashes grow and fall out in the same manner as they did before and during the therapy. However, after therapy, the difference may be noticeable as the intensive growth of the eyelashes is no longer stimulated and their life is not prolonged by the serum. The length, thickness and amount of eyelashes may decrease.

Which product has a better effect – the L4L serum or the 24-h mascara?

The action of the two above-mentioned products differs, which means that their efficacy cannot be compared. L4L serum stimulates the eyelash growth cycle, improving their condition and appearance. In turn, the 24-h mascara contains the ingredients that condition the eyelash fibre by strengthening the existing eyelash. The mascara is a perfect complement to the serum that enhances its efficacy. However, the mascara when used separately will never ensure such satisfactory results as the serum.


What is the difference between the L4L FX5 serum and the standard L4L serum?

The cosmetic industry is a very dynamically developing market, and the ongoing extensive research on new active substances provides opportunities to constantly improve the formulas used in products. The new 5-ingredient formula bases its efficacy on the Penthasymin complex, where the active peptide complex plays a key role. The formula has also been enriched with valuable oils that effectively nourish eyelashes and ensure their remarkable condition. However, if you are familiar with and use our first L4L serum and trust its effects, you can continue to enjoy them using the same product. But if you love to seek and experiment with new cosmetics, we recommend that you try our new formula – you will not be disappointed.

What does the serum contain?

This multi-active serum with FX5 formula is based on innovative Penthasymin complex containing active peptides supported by moisturising-nourishing substances, like sweet almond oil or rice bran oil. Additionally, hyaluronic acid cares for the eyelashes’ moisturization level and Provitamin B5 gives them soft and glossy appearance.


What is the proper way of using the serum?

Once daily, in the evening, apply the serum along the upper lash line – from the inner to the outer corner.

Can the serum be used after chemotherapy?

Before we introduced the product on the market, we conducted safety and efficacy testing on healthy people under the supervision of a dermatologist and an ophthalmologist. We recommend consulting your doctor about using the serum after oncological treatment.

Can the serum for lashes be used during breastfeeding?

Before we introduced the product on the market, we conducted safety and efficacy testing on people who were not pregnant, under the supervision of a dermatologist and an ophthalmologist. We recommend that pregnant women should postpone the start of the therapy until the end of the confinement period. It relates to ensuring total safety as well as balancing possible hormonal disruptions during and after pregnancy that could influence the condition of the skin and hair.

What is the consistency of the serum?

Semi-transparent gel – the consistency ensures safe use as the product does not fall into the eye.

Are products with such active substances safe to use?

Before we introduced our conditioner on the market, it had undergone dermatological and application testing that had been conducted on people with sensitive and allergy-prone skin (under the supervision of a dermatologist and an ophthalmologist). The testing conducted did not reveal any significant adverse effects.
The conditioner should not be applied directly into the conjunctival sac, but just on the lash line. If the product gets into the eye, it should be washed with abundant water. The serum, like all other cosmetics, may cause some adverse reactions – in rare cases they might include bloodshot eyes or eye reddening. If an allergic reaction to the cosmetic occurs, stop using it immediately.

The area around my eyes is irritated – why is that?

Adverse reactions may occur in people who, for example, apply too much of the serum, hoping it will speed up eyelash growth. More, in this case, does not mean better. We recommend applying a small amount of the serum on the upper lash line so that the conditioner does not get into the eye. If the irritation in the area around the eyes persists, we recommend you stop using the serum and consult a doctor.
