Microneedling is a relatively new minimally invasive procedure involving superficial and controlled puncturing of the skin by rolling with miniature fine needles.
Over a short period of time, it has gained mass popularity and acceptance as it is a simple, office-based, cheap, safe, and effective technique. Traditionally used as a collagen induction therapy for facial scars and skin rejuvenation, it is also widely used now as a transdermal delivery system for therapeutic drugs and vaccines. It was initially introduced for skin rejuvenation, however, now it is being used for a very wide range of indications including acne scar, acne, post-traumatic/burn scar, alopecia, skin rejuvenation, drug delivery, stretch marks, and many more.
Micropunctures are created using microneedles which produce a controlled skin injury without actually damaging the epidermis leading to wound healing cascade with release of various growth factors such as platelet-derived growth factor (PGF), transforming growth factor alpha and beta (tgf-î± and tgf-î²), connective tissue activating protein, connective tissue growth factor, and fibroblast growth factor (FGF).
This percutaneous collagen induction leads to an overall youthful appearance of the skin by reducing fine lines and wrinkles, reducing pore size, more suppleness, elasticity and collagen production.
