In microneedling a device with many fine needles – a motorised pen or a roller (dermaroller) – is guided across the skin. The tiny, controlled micro-injuries trigger natural wound healing, prompting the body to produce more collagen and elastin. This cosmetic form (collagen induction therapy) mostly uses needle depths of 0.25 to 1.5 millimetres; greater depths are reserved for medical professionals. Active serums such as hyaluronic acid are often worked in during or after treatment, as the channels improve absorption.
The process begins with cleansing and a numbing cream that acts for 20 to 30 minutes. The needling itself takes 20 to 40 minutes. Afterwards the skin is red like a mild sunburn, usually settling within one to three days. During this time sun protection, no make-up on treatment day and gentle care are important. Visible results don't appear immediately but over weeks, because collagen build-up takes time.
Microneedling suits large pores, acne scars, fine lines, uneven texture and early skin laxity. Several sessions four to six weeks apart are usually needed – often a course of three to six treatments. It is unsuitable with active acne, inflammation, eczema or herpes in the treatment area. Hygiene and sterile single-use needle modules are mandatory.
In Switzerland a microneedling session in a beauty studio usually costs CHF 150 to 300 per treatment, depending on the area and serums used (no guarantee). Course packages of several sessions are often discounted. Medical needling with greater needle depth costs more and belongs in a doctor's hands.
