Peptides. Small Molecules, Powerful Results. Powered by QUALASH QUA-X Complex®

Peptides are short chains of amino acids — the essential building blocks of proteins in the human body. In the world of advanced cosmetics, they’re renowned for their ability to stimulate, repair and renew.

When applied to the lash and brow area, peptides work by signalling the skin to produce key structural proteins like collagen and keratin. These proteins help nourish the follicle at its root, creating the perfect environment for visibly fuller, stronger, and longer hairs.

In short: peptides don’t just coat lashes and brows — they support them from within.

Our formulas are powered by advanced peptide technology, carefully selected to boost growth, protect against breakage, and restore density to thinning or sparse lashes and brows.

Each product is enriched with QUA-X Complex® — an optimized blend of the most effective and luxurious peptides for superior lash and brow transformation.

“Peptides show synergy and work well together, so I would look for a serum with a combination of peptides.”
