An independent study was designed to obtain objective evidence of the effects of the Vibra-Sonic® cleansing brush after one use and seven days use.

It was clinically proven that the Vibra-Sonic® cleansing brush helped skin to appear clearer + smoother, firmer + tighter, brighter + more radiant.


  • Twenty five volunteers aged 18 to 40 were recruited. The volunteers had healthy skin.
  • Instrumental and imaging-based measurements were made, together with volunteers’ self-assessment.
  • Subjects used the test product once in the clinic under supervision and daily at home for seven days. Assessments were made after a single use and after 7 days use.

Poryphrins / Texture - Canfield Visia®

Canfield Visia® is an image-based skin analysis system. Both left and right-side images were analysed and the parameters derived for each side.

The system detected differences both after first use and after a week’s use. In particular, the parameters Porphyrins* and Texture** were decreased significantly compared to Pre-Treatment values.

*Poryphrins - bacterial excretions lodged in the pores), therefore reduction is poryphrins = reduced bacteria in pores.
**Texture - primarily an analysis of skin smoothness, therefore decrease indicates reduced appearance of rough, dry skin.

Translucency - TLS Translucency Meter

The Translucency Meter (TLS) assesses how light interacts with the skin structure and pigmentation, absorption levels and sub-surface scattering phenomena.

Significant results across parameter Alpa, K and Area showed the use of the device leads to a more translucent (clear) skin supporting the claims of “Reduced appearance of dull skin” and “Improved skin radiance”, particularly with prolonged use.

The clinical study demonstrated that the Vibra-Sonic® cleansing brush was able to significantly improve skin parameters associated with blemish improvement, skin texture improvement, skin radiance and translucency.
