Objectives: Understand the principles of transdermal delivery system using microneedling and mesotherapy techniques Identify advantages of using a multi suction injector for effective transdermal delivery of drugs Introduction: Microneedling or percutaneous collagen induction therapy, has gained so much popularity over the recent years since it is a minimally invasive procedure used to address multiple skin conditions. By stimulating collagen production, microneedling is performed not just for skin rejuvenation but also to address conditions such as acne and acne scar, post-traumatic and burn scar, stretchmarks, alopecia, hyperhidrosis and many others.
