Les évaluations cliniques

01. Evaluation of cutaneous hydratation

02. Evaluation of anti-aging effects on fine lines and wrinkles

03. Study on sensitive skin’s cutaneous reactivity

04. Controlled clinical tests on the re-growth and proliferation of hair

05. The protocols for clinical tests at Pitié-Salpétrière Hospital



V. Clinical Evaluations

GREDECO Exclusivity

  • Analysis of the level of hydration
  • antiaging

01. Analysis of the level of hydration (with measuring apparatus)

Percentage of hydration in comparison with a benchmark :

  • Analysis of the level of hydration (with measuring apparatus) :
    - Percentage of hydration in comparison with a benchmark
    - Ultra-macrophotographs of skin with correlation to clinical scores (roughness, flakiness)
  • Trans-epidermal water loss
  • Level of sebum
  • Skin’s pH and temperature

02. Evaluation of anti-aging effects on fine lines and wrinkles

  • Prints evaluated by 3D analysis or by scanning electron microscope

anti-aging effectsEvaluation of anti-aging effects on fine lines and wrinkles

Non-invasive analysis of the skin microdepressionary network so as to create superficial prints of the skin. To measure the area lying between the wrinkles (μm2), pictures are taken for image analysis

03. Study on sensitive skin’s cutaneous reactivity

- By the “stinging test“

  • In order to identify subjects with sensitive skin, a “stinging test“ is conducted using lactic acid
  • “Stingers,“ qualifying subjects testing positive to this test, participate in a controlled study using a soothing moisturizing cream in comparison to the product of reference
  • Auto-evaluation and establishment of scores according to tingling sensation

By remaining (by way of under-treatment) within the threshold of sensitivity to temperature and electricity according to CJLA

  • Measurement of average thresholds of perception and intolerance to temperature stimulants
  • Measurement of tingling sensation after electric stimulation
 

04. Controlled clinical tests on the re-growth and proliferation of hair :

  • Centre specialized in hair grafting
  • Phototrichograms of inclusion and follow-up : number of hairs in different stages (anagen, catagen, telogen), average length, standard deviation, rate of re-growth, and speed of spontaneous growth and that which follows treatment/li>
  • Auto-evaluation of improved appearance and tolerance
