结局指标
主要结局
Change in POH severity
时间窗: 3 month follow up
POH improvement of at least 1 point evaluated by the investigator at the 3-month follow up compared to baseline using the POH severity in comparison to surrounding skin scale where score of between 0 and 4 will be assigned (0-Normal (Skin color comparable to other facial skin areas); 1- Trace (Faint pigmentation of infraorbital fold (bilateral)); 2- Mild (Pigmentation more pronounced); 3- Moderate (Deep dark colour, all four lids involved): ; 4 - Marked (Grade 3 + pigmentation spreading beyond infraorbital fold)
次要结局
- Aesthetic improvement(3 month follow up)
