Participants' quality of life regarding facial spots for participants with Melasma assessed through a Quality of Life Questionnaire (MELASQoL)
時間枠:Before and after Visit 2 (14+2 days), Visit 3 (28+2 days), and Visit 4 (56+2 days) of IP use
|
Melasma Quality of Life Scale (MELASQoL) will only be answered by participants enrolled in Melasma group. The participant will answer a questionnaire with 10 questions regarding the condition of their skin, using a rating scale from 1 to 7, in which: 1 means "not at all bothered" and 7 means "bothered all the time". A total score will be generated by summing the scores of the 10 questions answered by the participant. The total score ranges from 10 to 70. The lower the score, the better the participant's quality of life. |

Participants' quality of life regarding facial spots for participants with Solar Lentigo or Post-Inflammatory Hyperpigmentation assessed through a Quality of Life Questionnaire (DLQI)
時間枠:Before and after Visit 2 (14+2 days), Visit 3 (28+2 days), and Visit 4 (56+2 days) of IP use
|
Dermatology Life Quality Index (DLQI) will only be answered by participants selected for the Solar Lentigo/PIH Group.
The participant will answer a questionnaire with 10 questions regarding the impact of their skin on their quality of life.
Each question is scored on a four-point Likert scale: very much = 3 points, much = 2 points, a little = 1 point and nothing/not relevant = 0 points.
Questions answered as nothing and not relevant are equivalent to 0 points.
The total score ranges from 0 to 30.
The lower the score, the better the participant's quality of life.
