Advanced Lash Treatment Duo Set

QUALASH® Advanced Eyelash Growth Serum Duo Set includes 2 bottles of our advanced, science-developed eyelash serum created with QUA-X Complex™— a proprietary growth-conditioning formula that nourishes, strengthens and visibly improves the appearance of natural lashes, giving them the look of greater length, a fuller lash line, healthy shine and a darker appearance.

What you can expect

With regular use, your lashes become visibly longer, fuller and healthier-looking — while your eyes gain a more expressive, defined and naturally enhanced look. First visible results can be noticed after 4 weeks, while the fuller effect develops throughout a 12-week treatment routine.

QUALASH® was developed for weak, sparse and fragile lashes to support their denser, stronger and more spectacular appearance. After completing the treatment, the serum can be used 2–3 times per week to maintain the effect of more beautiful, expressive lashes.

How to Use

How to apply QUALASH® lash serum

Remove makeup and cleanse the eye area. Make sure the skin along the upper lash line is clean and dry before application.
Apply one thin stroke of serum along the upper lash line, like an eyeliner. One dip is enough for both eyes.
Use once daily, preferably in the evening, and allow the serum to dry before applying other skincare or makeup products.

Treatment routine

First 12 weeks: apply once daily.

Maintenance: after completing the treatment, apply 2–3 times per week to maintain the effect.

Important

Apply only to the upper lash line.
Do not apply to the lower lash line.
Avoid direct contact with the eyes.
Using more product will not improve results and may increase sensitivity.
Do not use if you are pregnant, breastfeeding or under 18.
Keep out of reach of children.
If redness or irritation occurs, discontinue use.
If you have any pre-existing eye conditions, consult your doctor before use.
For full instructions and precautions, read the enclosed leaflet before use.

FAQs

How does Qualash 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 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.

Reviews Summary ✨ ✧

Based on reviews, many customers using QUALASH regularly confirm that their lashes become longer, thicker and visibly darker. Noticeable changes are most often described between weeks 3 and 8, although some users notice a difference after around one month. Customers often mention the precise brush applicator, the fact that one package lasts for several months of use, and confirm accelerated regrowth of new lashes after artificial extensions.

Overall, positive feedback prevails, and regular users frequently make repeat purchases, highly rating the convenience of automatic deliveries in the subscription model.
