The following washout periods for prior medications apply: 14 days for topical treatment, 1 month for oral antibiotics, and 6 months for oral isotretinoin. Patients using oral contraceptive must have used the same product and dose for at least 3 months and agree to stay with the same product and dose during the study participation. Patients that have had facial procedures like dermabrasion, chemical or laser peels within the last month will be excluded. Patients using testosterone, any other systemic hormonal treatment or hormonal contraceptives solely for control of acne will be excluded.

E.5 End points |
E.5.1 | Primary end point(s) |
Absolute change from baseline in facial inflammatory lesion count (nodules, papules, and pustules) 12 weeks after the first treatment. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
12 weeks after first treatment |
|
E.5.2 | Secondary end point(s) |
Absolute change from baseline in facial non-inflammatory lesion count (open and closed comedones) 12 weeks after the first treatment.
Percent change from baseline in facial inflammatory (nodules, papules, and pustules) and non-inflammatory (open and closed comedones) lesion counts 12 weeks after the first treatment.
Proportion of patients with success according to IGA scale based on the facial assessment at 12 weeks after the first treatment. One scale will be used including inflammatory and non-inflammatory lesions. Success is defined as an improvement of at least 2 grades from the baseline score.
Pain during illumination using a Visual Analogue Scale (VAS) from 0 to 10, where 0 indicates no pain and 10 indicates the worst pain imaginable.
Percent of patients with local (facial and non-facial treatment site) and non-local adverse events.
