Trilogy commissioned an independent clinical study to test the effect of the topical application of Trilogy Certified Organic Rosehip Oil on stretch marks.
The study was conducted at an independent laboratory in Australia during 2009, in accordance with ICH Guidelines for Good Clinical Practice.
Conclusions of Study
Self assessment
All 10 test subjects reported an improvement in the overall appearance of the stretch mark at the 8 week and 12 week time points. All subjects reported a reduction in the appearance of their stretch marks and improvements in the firmness, smoothness, colour and tightness of the stretch marks.
Expert Clinician Assessment
Apparent area, erythema (colour) and appearance of the stretch marks were all observed to significantly and consistently improve over the duration of the study.
- 43% improvement in visible area of stretch marks
- 32% improvement in depth of stretch marks
- 31% improvement in width of stretch marks
- 26% improvement in colour of stretch marks
Expert assessment of the improvement of the appearance of stretch marks
- 10 subjects between the ages of 20 and 60.
- Subjects showed evidence of discrete stretch marks on the upper leg or torso of mild to severe intensity.
- Assessments of the test sites were completed pre-application and following use after 4, 8 and 12 weeks.
- A photographic record was kept of the stretch mark area appearance at each time point.
- For one test subject, two areas were chosen and separately monitored to allow for intra-subject comparison.
- Application was twice daily.
- Concurrent use of other skincare products was not permitted in the skin area under study.
- No adverse responses were observed during the study.
Individual results may vary.
