CIDP specialises in the conduct of anti-acne studies on various skin panel (Indian, Asian, Caucasian, African). The tests are designed under dermatological control and the study design can be adapted over a period of 1-3 months depending on claim substantiation. 

Background pic


  • Acne Count (in vivo or from digital photographs) by Dermatologist using IGA, GEA scales
  • Digital Photographic Techniques followed by Image Analysis for the measurement of different acne parameters (with VISIA-CR®, Photobecnch®, Colorface®)
  • Clinical Scoring of acne severity and density according to pre-defined scales such as Acne Leeds Grading. 
  • Fringe Projection and 3D Photographic Technique to obtain 3D images of acne lesions followed by Image Analysis
  • 2D Profilometry: Skin imprints on silicon followed by Imprint Analysis
  • Skin Microbiome sampling: A microbial sampling can be done at the end of the study to study the skin microbial flora


It is also possible to evaluate the anti-seborrheic efficacy of the products during the study by:

  • Instrumental Technique:

–  Sebutape (coupled with the QuantiSeb Software),

–  Sebumeter® to measure the sebum secretion

–  VisioScan® (Coupled with sebum sensitive foil)

  • Digital Photographic Technique followed by Image Analysis
  • Coupled with subjective evaluation by volunteers


The determination of Astringent effect of a product is also coupled in Anti-Acne study which aims at determining the property of the product in cleansing the skin and tightening the pores.  

Evaluation of the Astringent Effect of your Products by: 

  • Digital Photographic Technique or High Resolution Dermoscopic Picture followed by Image Analysis
  • Fringe Projection and 3D Photographic Technique to obtain 3D images followed by Image Analysis
  • Dermatological Evaluation according to Photographic scales
