Clinical Studies

Clinical Trials Summary

Our belief in the naturally active properties of Tamanu Oil is also backed by modern cosmetic research.

We have tested our formulations in volunteer studies for clinical efficacy in the following important cosmetic end-points:

wrinkle reduction  stretch mark reduction  skin firmness  skin elasticity

skin moisturisation  scar reduction  skin softness and skin smoothness

wrinkle reduction

Using the PRIMOS(Phase-Shifting rapid in vivo measurement of the skin) technique the Crow’s Feet area next to the eyes was recorded as a 3D topographical image before and after treatment. After 28 days the depth of wrinkles was reduced by over 14%.  Recommended to use Tamanu Care™ Intensive Therapy Cream or Regenerating Cream.

stretch mark reduction

Subjects with visible stretch marks applied the product twice daily for 28 days and evaluated effectiveness by direct self assessment.  65% of the subjects attributed a reduction in visibility of the stretch marks to application of the product.  Recommended to use Tamanu Care™ Scar and Stretch Mark Cream or Intensive Therapy Cream.

skin firmness

The skin’s bio-mechanical properties are assessed using the Cutometer SEM 575.  Measurements are based on the vacuum-suction principle:  1 second suction(450 mbar vacuum) followed by 1 second retraction; penetration depth of skin recorded optically.

After 28 days skin firmness had increased by up to 10%.  Recommended to use Tamanu Care™ Regenerating Cream.

skin elasticity

Also assessed using the Cutometer SEM 575(see skin firmness above).  After 28 days skin elasticity had increased by 14%.  Recommended to use Tamanu Care™ Dry Skin Cream or Skin Soothing Cream.

skin moisturisation

The moisture level of the skin was measured using the Corneometer CM 825 PC which works on the basis of measuring electrical capacitance of the skin.  After 28 days the moisture level of the skin was shown to have increased by over 10%.  Recommended to use Tamanu Care™ Dry Skin Cream or After Sun Lotion.

scar reduction

Patients with aged scars were treated over a 9 week period and used a Visual Scoring system which referred to scar appearance characteristics(colour, roughness and difference to surrounding skin) and scar length and width.  In a scoring system where 0 is normal skin and 4 is scarred skin, the collective average was to move from 3.7 to 1.5 over a 9 week period.  Recommended to use Tamanu Care™ Scar and Stretch Mark Cream or Intensive Therapy Cream.

skin softness

Subjects with visible stretch marks applied the product twice daily for 28 days and evaluated effectiveness by direct self assessment.  90% of the subjects found the skin to have become softer.  Recommended to use Tamanu Care™ Dry Skin Cream or Foot Cream

skin smoothness

Assessed utilising PRIMOS(Phase-Shifting rapid in vivo measurement of the skin) – a non-contact measurement device which allows for real time 3D measurement of the micro-topography of human skin.  After 28 days skin smoothness had improved by over 14%.  Recommended to use Tamanu Care™  Hand & Body Lotion or Intensive Therapy Cream.
