Microneedling
A minimally invasive procedure using fine needles to create controlled micro-injuries in the dermis, stimulating collagen and elastin production.
Full Definition
Microneedling (also called collagen induction therapy) involves passing a device studded with fine needles across the skin surface, creating thousands of micro-channels that trigger the wound-healing cascade and neocollagenesis. Depth of needle penetration varies by treatment area and indication. Editors should note that 'microneedling' is written as one unhyphenated word in current clinical literature, distinguishing it from 'radiofrequency microneedling', which combines the mechanical stimulus with RF energy. 'Micro-needling' (hyphenated) is an older variant that should be standardised to the current unhyphenated form.
Usage
Usage note: Write as one unhyphenated word: 'microneedling'. Clearly distinguish from 'radiofrequency microneedling', which is a separate, more advanced modality.
