FAQs

How does Eyelash Serum work?

The serum uses advanced nanocell technology and a proprietary growth-support formula to nourish the lash root environment and support the natural lash growth cycle.
How long does the full treatment take?

A full treatment typically takes 8–12 weeks, which aligns with the natural lash growth cycle and reflects the complete lash growth and renewal process. Consistent daily use is essential for optimal results.
When will I see results and what effects can I expect?


Most users notice the first visible results after 3–4 weeks of regular use.

The serum works in harmony with the natural lash growth cycle, which typically lasts 8–12 weeks, so full results develop gradually. With continued use, lashes appear noticeably longer, thicker, and fuller, with improved density and overall condition.
Are Eyelash Serums safe?

Yes. QUALASH® Eyelash Serum has been dermatologically tested and assessed under strict European cosmetic safety standards.

As with any cosmetic product, we recommend a patch test before first use.
How long does one serum last?

With regular daily use, one QUALASH® Eyelash Serum lasts approximately 4–6 months, depending on application amount and consistency.
How should I use the serum to achieve and maintain results?

For optimal results, apply the serum once daily for the first 3 months.

After achieving the desired effect, reduce application to 2–3 times per week to maintain results and prevent lashes from becoming excessively long.
Can I use the lash serum if I have lash extensions?

Yes, the lash serum can be used with lash extensions. Apply it once daily on clean, dry skin, 1–2 mm above the upper lash line, just like an eyeliner.

Do not apply the serum directly onto the lashes or extensions themselves, as the product is designed to work at the lash root area.
Will my lashes fall out if I stop using the serum?

No. The serum supports the natural lash growth cycle and does not cause sudden lash loss when discontinued. If you stop using it, lashes gradually return to their natural growth rhythm, without a rebound effect.
What if I don’t see the results I expected?

The serum is scientifically tested and its effectiveness has been confirmed in application studies. However, results may vary depending on consistency, correct use, and individual lash growth cycles.

If the serum is used as directed and you are not satisfied with the results, we offer a 90-day money-back guarantee, in accordance with our return policy.
