Why QUALASH works

QUALASH works by activating the natural lash growth process.

The patented growth formula, powered by the proprietary QUA-X Complex™ and advanced nano-cell technology, supports the lash root environment, helping lashes appear longer, fuller and stronger over time.
When you’ll see results


• First visible results in 3–4 weeks

• Full results after 8–12 weeks of regular use

• After completing the full cycle, apply 2–3 times per week to maintain results
How to use

Apply a thin line once daily in the evening to clean, dry lashes, directly along the lash line.

Allow the serum to fully absorb before applying any other products.

One bottle contains 3.5 ml and lasts approximately 4–6 months with regular use.

After completing the full treatment cycle, apply 2–3 times per week to maintain results.
Safety & Formula

✓ Ophthalmologically and dermatologically tested

✓ Vegan & cruelty-free
