Treatment groups
Trial outcomes
Primary outcomes
Skin collagen and elastin quantification
Assess with biopsy based histological examination
Facial wrinkles
Wrinkle severity score measured by Facial Image Analysis System (BTBP 3D image analysis system). Higher scores indicate worsened wrinkle severity and lower scores represent improvement in wrinkle severity.
Secondary outcomes
Pigment intensity score
Change in the appearance of facial pigmentation by high resolution photography (BTBP Clarity Pro) and measures intensity of facial pigmentation. Higher scores indicate darker pigmentation.
Pigment intensity score
Change in the appearance of facial pigmentation by high resolution photography (BTBP Clarity Pro) and measures intensity of facial pigmentation. Higher scores indicate darker pigmentation.
Expression of enzymes that either degrade collagen (MMP1) or inhibit collagen degradation (TIMP1) on skin biopsies
Assess through biopsy based histological examination
Plasma for potential AGE (advanced glycation end products) analysis
Blood samples will be collected
