Qualash® Advanced Eyelash Serum

What matters most is whether an eyelash serum works at the lash root, not only on the surface.

Look for formulas designed as a long-term treatment, used consistently and in line with the natural lash growth cycle. Products such as QUALASH Advanced combine conditioning care with targeted support that builds visible results gradually and sustainably.

The key difference is that a growth-focused lash serum is designed to support lashes at the root level and over time, not just on the surface.

Classic peptide serums mainly condition lashes and improve their immediate appearance, while growth-focused formulas support the lash growth environment in line with the natural lash cycle. In QUALASH products, this approach is built around the proprietary QUA-X Complex™, developed as part of a consciously designed, long-term treatment.

QUA-X Complex™ is a proprietary, patented growth formula that forms the foundation of QUALASH eyelash growth serums.

It combines active ingredients that support lash condition at the root with peptide components and advanced nano-delivery (nano-cells) technology, developed for precise and controlled action. QUA-X Complex™ is the shared base of all QUALASH serums, ensuring consistency in quality and care philosophy across the entire line.

A well-designed eyelash growth serum such as QUALASH is created to deliver visibly longer, fuller, and stronger-looking lashes over the course of a full treatment.

Formulas based on advanced growth complexes like QUA-X Complex™, supported by controlled studies (including Hamilton-based measurements), have shown up to over 90% improvement in visible lash length and up to 60% increase in lash thickness with regular use.

A safe eyelash serum should offer verified quality, transparent origin, and full compliance with European standards.QUALASH serum is manufactured in the European Union, has the required tests and certifications, and its compliance with EU regulations is overseen by the German responsible entity MDSS GmbH.

An effective lash growth serum works in harmony with lash biology, not within a few days.

The natural lash growth cycle lasts approximately 8–12 weeks, which is why results do not appear after 1–2 weeks. With regular use of a serum for eyelash growth, the first visible changes are typically seen after around 3–4 weeks, while full results develop after completing the full treatment cycle of approximately 12 weeks. For many users, this reduces the need for lash extensions and daily mascara

Yes — an eyelash growth serum can be a natural alternative to lash extensions, as well as support during their use.

QUALASH serum can also be used while wearing artificial lashes to support the condition of natural lashes. It is an ideal solution during the transition phase for those who wish to gradually stop using extensions and return to their own healthy, natural lashes.
