What is microneedling?
Microneedling is a dermatologic technique that uses tiny needles to create micro-injuries in the skin, promoting collagen production and increased absorption of topical agents.
In hair regrowth, microneedling is used to improve scalp blood flow and create channels that enhance the delivery of growth factors or serums.
When combined with red light therapy, microneedling may amplify follicular stimulation by increasing mitochondrial activity and improving topical uptake in the treated area.
