You've probably seen images of long, full lashes and come across eyelash serums that promise visible results. It's completely natural to wonder — do they actually work, and what should you keep in mind?
In this article, we clear up the most common questions and myths around eyelash serums. What's true, what's a misunderstanding, and what can you realistically expect? Here you'll find the answers that help you make a confident, informed decision.
1. It's a quick fix
False: We won't claim that Xlash Eyelash Serum is a miracle product. Its effectiveness has been demonstrated in clinical studies, but it's worth noting that it takes around four weeks before you start to see improvements in your lashes. What matters is that you use the product consistently every night before bed for at least 4 weeks to see results.
2. They can help lashes feel stronger
True: An eyelash serum like Xlash Eyelash Serum can help to strengthen and nourish your lashes, especially if they feel dry or brittle. When the serum is applied along the lash line, nourishment is delivered directly to the roots, which can support your lashes' natural growth cycle.
The result is lashes that feel stronger, more resilient, and less prone to breaking.
3. Using eyelash serum twice a day gives faster results
False: The recommended usage for maximum effect is once a day, preferably before you go to bed. That's enough to develop richer, more beautiful lashes. Using the product twice a day won't give you faster results — there's only so much your lashes can absorb.
4. They're safe to use
True: Most eyelash serums are completely safe to use. Xlash Eyelash Serum is formulated with only natural extracts, vitamins, and minerals that have been clinically proven to be safe and effective. It's free from harsh chemicals, which means you can use the serum without any worries.
5. Does Xlash or Xbrow contain prostaglandins?
One of our active ingredients is Dechloro Dihydroxy Difluoro Ethylcloprostenolamide (0.0015%), which is a prostaglandin analogue.
All ingredients used in Xlash and Xbrow have been approved under EU legislation for use in a cosmetic product. Their safety in this formula has been evaluated and confirmed.
This ingredient can be found in the EU's database of cosmetic ingredients as an ingredient that may be used in cosmetics. Its function is to condition the hair. We use this conditioning effect to support the natural growth of lashes and eyebrows.
Prostaglandins are lipid compounds found in almost all tissues in the human body. Prostaglandin analogues mimic the function of naturally occurring prostaglandins. Different prostaglandins have different effects, and they can influence natural reactions in the body when present. It's important to note that there are different prostaglandins and prostaglandin analogues, and they can work differently.
Prostaglandins act as messengers, but they generally have a short half-life, so it doesn't take long before they are inactivated and excreted by the body. For this reason, they can only affect cells that are nearby. This means our lash and brow conditioning formulas can only act locally to condition hair where the product is applied.
It's also important to pay attention to the concentration of the active ingredient. Our formula contains 0.0015% of the active ingredient. This extremely low concentration has been shown to support lash growth through its conditioning effect, but in our safety tests where the product has been used as intended, we have not encountered any side effects.
In studies examining the safety of eyelash serums, the safety profile of prostaglandin analogues has generally been considered good when applied topically at the base of the upper lashes.
Unwanted side effects of prostaglandin analogues are typically only reported in studies where higher concentrations of medically used prostaglandin analogues are present in a medical solution that is repeatedly in direct contact with the eye.
If Xlash comes into contact with the eye, it is always recommended as a precaution to rinse with clean water to avoid any unforeseen and unwanted effects and eye irritation.
6. You can't use them during pregnancy or whilst breastfeeding
False: Although the Xlash range has been shown to be safe in several studies carried out by independent research laboratories, no studies have been conducted on pregnant or breastfeeding women. For this reason, you should consult a doctor before starting to use the serum if you are pregnant or breastfeeding.
7. No long-lasting results
True/False: Well, from one perspective this statement is true — if you stop using an eyelash serum once you've achieved the lash growth you're happy with, your lashes will return to their original appearance after a few weeks or months. On the other hand, if you want to maintain the look of longer, healthier lashes, you'll need to continue applying the eyelash serum 2–3 times a week — and that way, you'll enjoy long-lasting results.
8. They're difficult to use
False: Once you get the hang of it, eyelash serums like Xlash Eyelash Serum are incredibly easy to use. Just remember to remove all makeup before applying it. Use the small brush and apply a thin line along the roots of your lashes before you go to bed.
9. They're formulated with natural extracts
True: Or we can only speak for ourselves, of course. Xlash Eyelash Serum is made up of natural plant extracts and other safe ingredients.
10. You won't see results if you don't use it correctly
True: To achieve longer and thicker lashes with Xlash Eyelash Serum, it's important to use it regularly and according to the instructions. What matters isn't how much product you apply, but rather that you use the growth serum every night for at least 28 days. Don't worry if you forget to use it one night — just apply it again the following evening.
To summarise
Hopefully you now have a clearer picture of how eyelash serums work and what's actually true. For many people, it's a straightforward way to give their lashes a little extra care and support in their natural growth.
If you're curious to try it for yourself, a serum like Xlash Eyelash Serum could be a simple addition to your routine — for lashes that feel stronger, fuller, and more defined over time.
