EFFICACY - In vivo efficacy tests
EFFICACY TEST N°. 1
Type of study: Clinical test conducted on women suffering from recently formed stretch marks.
Aim: to clinically, structurally and objectively assess, under medical supervision, the efficacy of Labo Stretch Marks on stretch marks after a 2 month period of treatment. The testing conditions adopted (skin treated area, quantity of applied product, frequency and duration of application) reproduced the normal conditions of use of the treatment.
Type of test: In vivo test on 20 subjects.
Test duration: 2 months.
Date carried out: November 2006.
The results obtained from the study confirm that the products being tested showed good cosmetic efficacy in treating stretch marks. The elastimetry test in particular demonstrated a noticeable increase in skin elasticity thus confirming the efficacy of the products in treating stretch marks that, generally speaking, usually have poor elastic properties. The colorimetry test demonstrated that treatment with the products being tested led to a noticeable reduction in the redness of recently formed stretch marks thus making them less obvious. This factor was further confirmed by photographs taken during the study. Volunteers' opinions about cosmetic efficacy bear out the results and underline that the products being tested were highly praised as they reduced stretch marks, made them less obvious and softened their colour as well as moisturising the skin and making it more elastic and smoother.
Cosmetic efficacy was also assessed by means of taking macrophotographs of the areas of skin recently affected by stretch marks at the beginning of treatment then after 4 and 8 weeks.
A comparison of photos taken at differing times during the observation period clearly shows the cosmetic efficacy of Labo Stretch Marks in treating stretch marks.
Most significant photos:
Volunteer n. 4 - Age 24
Photo of the skin on the abdomen of volunteer 4 before treatment.
Photo of the skin on the abdomen of volunteer 4 after 4 weeks of treatment.
Photo of the skin on the abdomen of volunteer 4 after 8 weeks of treatment.
EFFICACY TEST N°. 2
Type of study: self-assessment conducted on women with recent stretch marks.
Aim: To establish a customer satisfaction index regarding the efficacy of Labo Stretch Marks on stretch marks. The testing conditions adopted (skin treated area, quantity of applied product, frequency and duration of application) reproduced the normal conditions of use of the treatment.
Type of test: self-assessment conducted on 91 subjects with recent stretch marks.
Test duration: 1 month.
Date carried out: February 2007.
- 75% of the women interviewed for this survey stated that they had noticed a reduction in their stretch marks following the application of the product. The difference between the percentage of women who noted a reduction in their stretch marks (75%) and those who had not noticed any reduction (25%) is statistically significant.
- Almost all members of the sample cohort felt that use of the product rendered the skin more supple, and smoother. Likewise in this instance, the difference between the percentage of women who noticed an improved suppleness and smoothness of the skin (99%) and the percentage perceiving no such benefit (1%) is statistically significant.
- Almost 42% of the women sampled found the product easy to apply. 32% consider the method complicated but functional, whilst 19% state that application of the product is complicated, and 8% claim that it is difficult. The number of "easy" answers is greater and statistically significant as opposed to the number that felt application was "complicated" or "difficult".
