Trilogy commissioned an independent clinical study to test the effect of the topical application of Trilogy Certified Organic Rosehip Oil on scars.

- A photographic record was kept of the scar area appearance at each time point.
- For one test subject, two areas were chosen and separately monitored to allow for intra-subject comparison.
- Trilogy Certified Organic Rosehip Oil was applied twice daily.
- Concurrent use of other skincare products was not permitted in the skin area under study.
