Medical Microneedling — Collagen Induction Therapy

Collagen induction therapy (CIT), commonly called microneedling, works through a carefully calibrated controlled injury to the dermis. When a needle penetrates the dermis, it creates a micro-wound that does not break the epidermis if performed within the papillary dermis (0.5–1.5 mm) — or does produce a controlled superficial breach at reticular dermis depth (1.5–2.5 mm) when deeper collagen remodelling is the target. Either way, the local tissue response…

At Esthé Laser Clinic, the medical microneedling device creates needle entries at a controlled depth using a motorised stamping mechanism rather than a manual roller. This matters clinically: a roller draws the needle through the skin at an oblique angle, creating a tear-drag path rather than a true vertical puncture, which is less predictable in depth and more traumatic to the tissue. A motorised vertical stamping device punches each needle entry…

Before the session begins, topical anaesthetic cream (typically EMLA or equivalent) is applied to the full treatment area and left under occlusion for 45–60 minutes. Once adequately numb, the treatment area is cleaned and the device is passed across the entire face (or targeted area) in multiple directions — typically horizontal, vertical, and diagonal — to ensure uniform channel density across the region. The full pass typically takes 20–30 minutes.
