Exclusion criteria
Participants will wash their face with the study cleanser (Neutrogena Ultra Gentle Daily Cleanser with Pro Vitamin B5) for up to 14 days.
Participants will cover their closed and popped pimples in the evening with one or two bandages from Days 0 through 6.
Time frame: Baseline (Day 0) up to Day 14
Change from baseline in general wound appearance of the popped pimple will be assessed. It is evaluated on a scale from 0 to 4 with 0=poor (new or fresh wound with the epithelium layer missing, wound bed appears raw and possibly oozing); 1=fair (epithelial growth is starting to occur, wound bed is dry); 2=good (epithelial growth is clearly evident, wound bed color is no more than moderate erythema, scabbing may be present); 3=very good (wound bed indentation is slightly visible, wound area is mostly covered with epithelial regrowth, slight scabbing may be present); 4=excellent (fully healed, skin flush against surrounding skin, slight color mismatch may be present), with higher scores indicating a better outcome.
Time frame: Baseline (Day 0) up to Day 14
Percentage of healed popped pimples is defined as general wound appearance score greater than or equal to (>=) 3.5. General wound appearance is evaluated on a scale from 0 to 4 with 0=poor (new or fresh wound with the epithelium layer missing, wound bed appears raw and possibly oozing); 1=fair (epithelial growth is starting to occur, wound bed is dry); 2=good (epithelial growth is clearly evident, wound bed color is no more than moderate erythema, scabbing may be present); 3=very good (wound bed indentation is slightly visible, wound area is mostly covered with epithelial regrowth, slight scabbing may be present); 4=excellent (fully healed, skin flush against surrounding skin, slight color mismatch may be present), with higher scores indicating a better outcome.
Time frame: Baseline (Day 0) up to Day 14
Change from baseline in full face cutaneous tolerance as assessed by trained graders will be reported. It is evaluated on 3 criteria's: erythema, edema and dryness/scaling, all with a range of 0=none/absent, 1=mild, 2=moderate, and 3=severe, with higher scores indicating a worse outcome.
Time frame: Baseline (Day 0) up to Day 14
Change from baseline in full face cutaneous tolerance as assessed by participants will be reported. It is evaluated on 3 criteria's: burning/stinging, itching and tight/dry feeling, all with a range of 0=none (no burning/stinging or itching or no skin tightness/dry feeling of the treatment area); 1= mild (slight burning/stinging sensation or itching or definite tightness or dry feeling of the treatment area; not really bothersome); 2=moderate (definite warm burning/stinging or itching or tightness or dry feeling of the treatment area that is somewhat bothersome) 3=severe (marked burning/stinging sensation or itching sensation or tightness/dry feeling of the treatment area that causes definite discomfort and may interrupt daily activities and/or sleep), with higher scores indicating a worse outcome.
Time frame: Baseline (Day 0) up to Day 14
Change from baseline in clinical grading of wound healing of a popped pimple will be reported. Grading of edema will be evaluated on a scale of 0 to 4 with 0=none/absent, 1=mild, 2=moderate, 3=marked; and 4=severe, with higher scores indicating a worse outcome.
Time frame: Baseline (Day 0) up to Day 14
Change from baseline in clinical grading of wound healing of crusting/scabbing of a popped pimple will be reported. Grading of crusting/scabbing will be evaluated on a scale of 0 to 4 with 0=none; 1=slight (up to 30 percent [%]); 2=moderate (31% to 60%); 3=extensive (61% to 90%); and 4=almost complete or complete (91% to 100%), with higher scores indicating a worse outcome.
Time frame: Baseline (Day 0) up to Day 14
Change from baseline in clinical grading of wound healing of smoothness of popped pimple as assessed by trained grader will be reported. Grading of smoothness will be evaluated on a scale of 0 to 4 with 0=rough, uneven wound, 1=mild smoothness, 2=moderate smoothness, 3=extensive smoothness, and 4=complete smooth, even wound, with higher scores indicating a better outcome.
Time frame: Baseline (Day 0) up to Day 14
Change from baseline in clinical acne grading of erythema of a closed and popped pimple will be reported. Grading of erythema will be evaluated on a scale of 0 to 4 with 0=none, 1=slight, 2=mild, 3=moderate, and 4=severe, with higher scores indicating a worse outcome.
Time frame: Baseline (Day 0) up to Day 14
Change from baseline in clinical acne grading of size (diameter) of a closed and popped pimple will be reported. Grading of size will be evaluated on a scale of 0 to 4 with 0=no visible lesion, 1=slightly visible lesion; less than (<) 2 millimeters (mm), 2=small lesion; 2.0 mm to 3.0 mm, 3=medium lesion; 3.1 mm to < 5.0 mm, and 4=large lesion; greater than or equal to (>=) 5.0 mm, with higher scores indicating a worse outcome.
Time frame: Baseline (Day 0) up to Day 14
Change from baseline in clinical acne grading of elevation of a closed and popped pimple will be reported. Grading of elevation will be evaluated on a scale of 0 to 4 with 0=completely flat, 1=slightly raised, 2=mildly raised, 3=moderately raised, and 4=severely raised, with higher scores indicating a worse outcome.
Time frame: Baseline (Day 0) up to Day 14
Change from baseline in clinical acne grading of dryness/scaling of a closed and popped pimple will be reported. Grading of dryness/scaling will be evaluated on a scale of 0 to 4 with 0=none, 1=mild, 2=moderate, and 3=severe, with higher scores indicating a worse outcome.
Time frame: Baseline (Day 0) up to Day 14
Change from baseline in IGA of acne severity will be reported. The IGA scale for acne reflects the Investigator's assessment of the severity of a participant's acne on a scale from 0 to 5 with 0 (clear skin), 1 (almost clear), 2 (mild), 3 (moderate), 4 (severe), 5 (very severe). Each of these gradations is based upon a lesion count by the Investigator.
Time frame: Baseline (Day 0) and Day 7
Microbiome analysis of closed and popped pimple for Days 0 and 7 will be reported. Microbiome sample swabs will be used to collect bacteria from the skin surface and will be processed by CosmosID Inc using spike-in quantification controls and shallow shotgun metagenome sequencing at 3-4 millions (M) reads per sample.
Time frame: Up to Day 13
Consumer perception will be assessed quantitatively by consumer perception questionnaire which consists of some questions regarding how participants feel about using the bandages. In order to capture this information, a smartphone app called dscout will be used that will allow the participants to easily provide the information with a glimpse of the experience. In each research activity, participants will be asked to answer a set of questions and submit a photo and/or video of him/her.
Time frame: Baseline (Day 0) up to Day 14
Standardized digital photographs of full face (right, center, left) will be captured using the Johnson & Johnson (J&J) Lab Imaging System for qualitative image analysis. It will assess visual improvements in closed and popped pimples.
