SCHOTT Vitryxx® Bioactive Glass 

Product Description

Chemically, bioactive glass is an amorphous structure (like all glasses) that consists solely of elements found in the body - silicon, calcium, sodium, phosphorous and oxygen. Decades of research and studies have demonstrated that bioactive glasses are highly biocompatible. For cosmetics and cosmeceutical products, the unique biocompatibility of bioactive glasses translates to absolute skin compatibility, as has been demonstrated repeatedly in several long- and short-term human skin patch tests. When activated with water, bioactive glass releases the ions of its composition as they possess a high bioavailability. Due to the mineral and inorganic character of SCHOTT Vitryxx® bioactive glass, this class of anti-aging ingredient is insensitive to light and temperature extremes.


In recent years, bioactive glass has been discovered to exhibit the following properties within cosmeceutical products:

1. Reduces redness on the skin
In cosmeceutical products, tests have shown, e.g., reduction of redness induced by UV treatment or chemical skin barrier damage.

2. Reduces visibility of wrinkles
Fast optical in-vivo topometry of human skin shows a significant reduction in visibility of wrinkle length and depth within a short period of time when using bioactive glass within cosmeceutical products.

3. Mineral enrichment
The mineral enrichment effect of bioactive glass is triggered by small amounts of water. This leads to the release of minerals, mainly calcium and silica, which can bind to nails.


As of today, a broad range of cosmeceutical products have been successfully formulated with SCHOTT Vitryxx®. These include:
  • Powder- and cream-based make-up
  • Skin care (e.g. facial cream, skin gel, after shave products)
  • Sun care 
  • Nail care (e.g. nail enamel, base coat)
  • Deodorants (e.g. stick, spray)
  • Permanent make-up colours

Technical Details

SCHOTT Vitryxx® Bioactive Glass Technology

In an aqueous environment a rapid ion exchange between the sodium ion of the bioactive glass matrix and the hydrogen ion from the water takes place. 
The fast release of sodium ions is accompanied by a somewhat slower release of bioavailable species like calcium ions, silica and phosphorous.
