Viqua® protects the skin — right down to its deepest layers

Collagen and Elastin are macro-proteins which form the structure of the skin’s deeper layers (see picture to the right). They’re also responsible for the skin’s overall firmness and elasticity.

Collagenase and Elastase are the enzymes which prevent the renewal of these deeper layers, and so cause wrinkles to appear.

In in vitro testing, Viqua® was shown to be a potent inhibitor of both Collagenase and Elastase at low concentration, and so helped to significantly reduce the symptoms of ageing associated with them.

  • Elastase inhibition
  • Collagenase Inhibition

Protecting blood micro-circulation

After four weeks of Viqua® treatment, the permeability of the skin’s blood vessels was significantly reduced and blood circulation increased.

Effectiveness inside cells

Viqua® scavenges free radicals from inside the mitochondria

A key in vitro study has shown Viqua® to be intelligently used by skin cells to cleanse free radicals inside their mitochondria, and so to restore healthy metabolism.

Human skin cells, adipocytes, were grown in a medium which also contained Viqua®, whose molecules were tainted with a fluorescent red marker to make them clearly visible under a microscope.

The resultant electron microscopy showed Viqua® to have successfully penetrated the adipocytes and to have localized itself within the mitochondria.

Further experiments subsequently showed Viqua® to be actively using the adipocytes’ mitochondria as a place to scavenge for free radicals.

Clinical results

The efficacy of Viqua® was clinically assessed in a trial involving thirty volunteers over a four-week period against a placebo. At the start of the trial, half of the participants chose Viqua® capsules, the other half placebo pills — no-one knowing which contained which.

At the end of the trial, the results gave scientific evidence to demonstrate a significant improvement of the Viqua®-taking volunteers’ skins:

  • Skin hydration rose significantly (+40%), whereas the placebo group saw a decrease (–0.3%).
  • The water content of the skin’s upper layers particularly improved with Viqua® (+51%).
  • Skin smoothness improved (+27%) — a significant decrease in depth of fine lines and wrinkles was recorded (volume: –26%).
  • Blood vessel remodelling suggested significant inhibition of inflammation processes.
  • Skin tone became generally brighter, and dark spot/blemish colour attenuated.
  • Moisturizing
  • Skin smoothness
  • Inflammation
  • Whitening

Volunteer self-assessment results mirrored the product efficacy results proven above. The Viqua® subjects also expressed a greater overall satisfaction score for the treatment vs. those given the placebo.
