Key ingredients, explained

The Advanced formula uses Myristoyl Pentapeptide-17, Myristoyl Hexapeptide-16, arginine and plant extracts, among others.

Myristoyl Pentapeptide-17

One of the most widely used peptides in lash serums, included to support the look of longer, thicker lashes.

Myristoyl Hexapeptide-16

A second peptide often paired with pentapeptide-17 in lash and brow formulas. Using several peptides is one reason Qualash scores well on formula.

Arginine

An amino acid, one of the building blocks of proteins such as keratin, which lashes are made of.

Plant extracts

Botanical ingredients that condition lashes and the skin along the lash line.

What to expect, and when

The manufacturer states that first visible changes may appear after about 25 days, and effectiveness was assessed in laboratory and consumer tests. Because each lash grows in cycles, full results take longer than first changes.

Manufacturer's consumer test

According to Qualash, a consumer perception test run by the laboratory J.S. Hamilton found that:

  • 88% of participants noticed longer-looking lashes
  • 86% saw a visible improvement after 25 days of regular use
  • 90% noticed healthier-looking, fuller-looking lashes

Perception tests record what participants report, not measured lash length.

How to use QUALASH® Advanced

  1. Apply once a day, ideally in the evening, on clean, dry skin with makeup and contact lenses removed.
  2. Draw one thin line along the base of the upper lashes, like eyeliner.
  3. Let it dry before applying other products or putting lenses back in.
  4. Use it every day. Skipping days slows visible results.

Follow the directions on the packaging if they differ.
