Seboregulation activity test and count of closed and open comedones

Regulatory reference: Guidelines to Commission Regulation (EU) No 655/2013
Claim: Non-comedogenic and Seboregulating
Application field: Visage and body cosmetics for oily skin.
Description of the test: Sebometric measurements in triplicate performed with Sebometer® at T=0 and T=X days after the treatment. Measurements will be performed on the cheeks after treatment. The untreated forehead will be used as a control. The measurements will compensate for circadian rhythms and will therefore be performed at the same time during the day. Open and closed comedones will be counted under Wood’s lamp illumination. Clinical evaluation of high resolution imaging will be performed using a contrast system at T=0 and after X days of treatment.
