      Aim of the study was to evaluate the soothing and re-epithelizing activity of a single&#xD;
      application of topical products on experimentally induced erythema by skin stripping on the&#xD;
      forearm (volar surface) of 20 healthy volunteers. In particular the activity of the following&#xD;
      three cosmetic products and the relative combinations (cream and serum) were assessed:&#xD;
      rejuvenating cream, rejuvenating serum, antioxidant serum&#xD;

Aim of the study was to evaluate the soothing and re-epithelizing activity of a single
      application of topical products on experimentally induced erythema by skin stripping on the
      forearm (volar surface) of 20 healthy volunteers. In particular the activity of the following
      three cosmetic products and the relative combinations (cream and serum) were assessed:
      rejuvenating cream, rejuvenating serum, antioxidant serum
allocation: Randomized
intervention model: Single Group Assignment
primary purpose: Treatment
masking: None (Open Label)
measure: Clinical evaluation of skin erythema: change from baseline, 1 hour after products application (T1h vs. T0)
time frame: After 1 (T1h) hour from products application
description: Skin erythema was scored and recorded according to the following grades: 0=no erythema; 0.5=very slight erythema (barely perceptible);1=well-defined erythema;1.5=moderate to severe erythema; 2=severe erythema (beet redness) to slight eschar formation (injuries in depth)

description: The instrumental measurement of erythema was performed by the use of an optical densitometer allowing to quantify, on a logarithmic scale, total reflected optical density (visual=V) and the values of primary subtractive colours of reflected light: cyan(=C), magenta(=M) and yellow(=Y). Calculation of erythema index was done as follows: E.I.=logRmagenta-logRcyan
measure: Optical densitometry: change from baseline, 6 hours from products application (T6h vs. T0)
time frame: After 6 (T6h) hours from products application

measure: Surface microrelief evaluation: change from baseline, after 1 hour from products application (T1h vs.T0)
time frame: After 1 (Th1) hour from products application
description: Morfometrical analysis of cutaneous surface allows the evaluation of the regularity of the microrelief (superficial cutaneous network). It was therefore possible to determinate the alteration of the microrelief caused by stripping.The evaluation of the regularity grade of cutaneous microrelief was possible using Fast Fourier Transform (FFT) on skin replicas obtained using silicone rubber. Skin replicas images were then acquired by a stereo microscope.
