What does the lash serum do?
⌄
It supports the natural lash cycle to help your lashes look longer, fuller and stronger over time. With consistent daily use, lashes appear more defined at the root and less prone to breakage — for a naturally enhanced look without extensions.
What results can I expect?
⌄
Most users report a gradual improvement: lashes look more visible, stronger and denser over time. Results vary depending on your lash cycle and consistency, but the goal is simple: a fuller-looking lash line and a more intense gaze, even without mascara.
Is it suitable for sensitive eyes?
⌄
The formula is designed for daily comfort and a lightweight feel. If you have very reactive eyes, wear contact lenses, or are prone to irritation, we recommend applying a very thin amount, avoiding the waterline, and doing a patch test first. Discontinue use if discomfort occurs.
Can I use it with extensions or a lash lift?
⌄
Yes. It can help maintain the appearance of your natural lashes. Apply on clean lashes and avoid the lash glue area if you wear extensions. For a lash lift, wait 24–48 hours after the service before resuming your routine (or follow your technician’s advice).
Can I use it on eyebrows too?
⌄
This product is formulated for lashes. While some customers apply it to brows, we recommend using it only as intended unless your product page explicitly states it’s suitable for eyebrows as well.
Is it safe for daily use?
⌄
Yes — it’s designed for a simple daily routine. Apply a thin line once a day on clean, dry skin at the lash root. Using more won’t speed up results: consistency matters more than quantity.
Is it suitable for sensitive eyes?
⌄
Our formula is designed for daily comfort. If you have very reactive eyes, we recommend a patch test and stopping use if irritation occurs.
Can I use it with extensions or a lash lift?
⌄
Yes. It can help maintain the look of your natural lashes. Apply on clean lashes and avoid the lash glue area if you wear extensions.
How do I apply the serum?
⌄
Apply a thin line at the lash root on clean, dry skin (like an eyeliner). One dip is enough for both eyes.
How often should I use it?
⌄
Once a day, preferably in the evening. Consistency is key for best results.
Can I wear mascara after applying it?
⌄
Yes. Let it dry fully first. If you apply in the evening, you can wear makeup as usual the next day.
When will I see results?
⌄
Most users notice visible improvements within 3–6 weeks, with optimal results around 8–12 weeks depending on your lash cycle.
Do I need to keep using it?
⌄
To maintain the look, we recommend switching to maintenance: 3–4 times a week after the initial routine.
What if I miss a day?
⌄
No worries — just resume the next day. Results come from consistency over time, not perfection.
What are the delivery times?
⌄
Orders ship within 24–48h. Delivery typically takes 2–5 business days depending on your location.
How can I track my order?
⌄
Once shipped, you’ll receive an email with your tracking link so you can follow your parcel until delivery.
