Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Selected patient will have bilateral accordion (cheek) wrinkles and will be randomized to receive 20 units of intradermal onabotulinumtoxin A injection on one side of the face and placebo (equal volume of intradermal normal saline injection) on the contralateral face. Patient will be monitored at 2, 4, 8, 12, and 16 weeks post injection for improvement of accordion wrinkles based on serial photographs assessed by the investigator who is blinded and also changes to the skin elasticity measured by a skin cutometer.

Treatment: Drugs
Comparator / control treatment
The contralateral side of the face will serve as control with a placebo where equal volume of normal saline is injected intradermally.

Summary
Brief summary
This study aims to evaluate the efficacy of intradermal onabotulinumtoxin A injection for the treatment of accordion (cheek) wrinkles as compared to placebo in a split face randomized and double blinded trial, in terms of improvement of wrinkles based on serial photographs, improvement in skin elasticity and patient's satisfaction. The hypothesis is that intradermal onabotulinumtoxinA is effective in treating accordion wrinkles and improving the skin elasticity, and with good patient's satisfaction.
