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.

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.

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.

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.

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.

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.

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.
