    FAQs

    1. How soon will I see results with Qualash® Eyelash Serum?


    Most users notice visible improvement in lash length and fullness within 14 to 21 days, with maximum results at 6 to 8 weeks of consistent use.
    What kind of results can I expect?

    In a consumer study:

    - 92% saw visibly longer lashes - 89% noticed fuller-looking lashes
    - 94% felt their lashes looked healthier and stronger
    (Based on self-assessment after 6 weeks of daily use)
    Why is Qualash® so effective?


    The secret lies in our patented QUA-X Complex™ — a next-generation formula combining multi-action peptides, plant-based extracts, and nutrient-rich conditioners that work in synergy to support lash growth.
    Unlike typical serums, Qualash® targets the root of lash development by stimulating follicles, improving strength, and nourishing lashes from within — without prostaglandins or harsh ingredients.
    Is Qualash® safe for sensitive eyes?

    Yes. Qualash® is dermatologist-tested and formulated without prostaglandins. It’s suitable for most users with sensitive eyes or contact lenses.
    Can I use it with eyelash extensions or mascara?

    Yes! Qualash® works well with extensions and mascara. In fact, many users say their natural lashes grow so much that they stop using extensions.
    Is Qualash® cruelty-free and vegan?

    Absolutely. All Qualash® products are cruelty-free, vegan, and made with responsibly sourced ingredients.
    Will my lashes fall out if I stop using the serum?

    No. Your lashes will gradually return to their natural growth cycle, but you won’t experience sudden loss or shedding.
    How long does one bottle last?

    One tube of Qualash® Eyelash Serum lasts approximately 5 to 6 months with daily use. A little goes a long way—just one stroke per day is enough.
    How long does one bottle (3.5 ml) last?

    One tube of Qualash® Eyelash Serum lasts approximately 5 to 6 months with daily use. A little goes a long way—just one stroke per day is enough.
    For comparison, many other lash serums offer only 1 ml or 2 ml for the same price or even more.

    With Qualash®, you get more product, more value, and visible results that last.
