E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
We aim at investigating if pretreatment enhances delivery of gold microparticles to the skin. |

To investigate the bio-distribution of gold microparticles in pretreated skin and compare it to the bio-distribution in non-pretreated skin by non-invasive imaging techniques |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
1. Patients with a clinical diagnosis of acne vulgaris, IGA score 1-3 2. 18-45 years of age at baseline 3. Legally competent, able to give verbal and written consent 4. Communicate in Danish verbally as well as in writing 5. Fitzpatrick skin phototype I-III 6.

E.4 | Principal exclusion criteria |
1. Subjects with a known allergy to gold microparticles or Epiduo 2. Individuals with other skin disease than acne or skin lesions in the area of research interest 3. Subjects with tattoo in the treatment area which may interfere with or confound evaluation of the study 4. Subjects with moderate-severe to severe acne (IGA 4-5 and those presenting with either cysts or nodules) requiring continuation of systemic treatment during the study period 5. Subjects with a history of keloids which is deemed clinically relevant in the opinion of the investigator 6. Subjects with active skin disease or excessive scarring that, in the opinion of the investigator, would impact the ability to administer the gold microparticles or use of OCT/RCM in the areas 7. Pregnant and lactating women 8. Subjects who have received investigational drugs or were treated with investigational devices within 30 days prior to baseline 9. Treatment with oral retinoid 3 months prior to baseline 10.
