- Percent of participants that experience pain during treatment
Based on responses to an investigator-developed survey completed by each participant within 5 days of treatment completion, participants will rate their pain from 1 to 5 where 1=no pain, 2= very mild, 3=mild, 4=moderate (requiring pain medication), 5=severe (requiring pain medication or physician contact). The number of participants with scores of 2 or higher will be divided by all participants.
- Severity of pain during treatment
Based on responses to an investigator-developed survey completed by each participant within 5 days of treatment completion, participants will rate their pain from 1 to 5 where 1=no pain, 2= very mild, 3=mild, 4=moderate (requiring pain medication), 5=severe (requiring pain medication or physician contact). Mean pain ratings will be calculated with higher mean scores suggesting more severe pain.
- Percent of participants that experience redness during treatment
Based on responses to an investigator-developed survey completed by each participant within 5 days of treatment completion, participants will rate their overall redness from 1 to 5 where 1=no redness, 2= very minimal, 3=minimal, 4=moderate, 5=severe. The number of participants with scores of 2 or higher will be divided by all participants.
- Severity of redness during treatment
Based on responses to an investigator-developed survey completed by each participant within 5 days of treatment completion, participants will rate their overall redness from 1 to 5 where 1=no redness, 2= very minimal, 3=minimal, 4=moderate, 5=severe. Mean redness ratings will be calculated with higher mean scores suggesting more severe redness.
- Day of worst redness
For participants who experienced any redness, the mean day after treatment when the redness was worst will be calculated.
- Percent of participants who experienced scaling/flaking
Based on responses to an investigator-developed survey completed by each participant within 5 days of treatment completion, participants will be asked if they experienced any scaling/flaking. The number of participants who responded 'yes' will be divided by all participants.
- Percent of participants who experienced skin itching

- Percent of participants who experienced skin burning
Based on responses to an investigator-developed survey completed by each participant within 5 days of treatment completion, participants will be asked if they experienced any skin burning. The number of participants who responded 'yes' will be divided by all participants.
- Participant compliance with treatment
Compliance with treatment will be assessed by weighing the medicine tubes after treatment completion and comparing the weight, estimated in grams from fingertip units (FTU), with the expected weight based on the how much medicine should have been used given the treatment regimen. The closer this difference is to zero, the greater the compliance.
- Participant satisfaction with treatment
Based on responses to an investigator-developed survey completed by each participant within 5 days of treatment completion, participants will rate their satisfaction with the treatment from 1 to 5 where 1=very dissatisfied, 2= dissatisfied, 3=neutral, 4=satisfied, 5=very satisfied. Mean satisfaction ratings will be calculated with higher mean scores suggesting more treatment satisfaction.
