Microneedling
Collagen induction therapy via micro-injuries
About This Treatment
Microneedling (Collagen Induction Therapy) uses 0.25-2.5mm fine needles to create controlled micro-punctures, leveraging natural wound healing for collagen synthesis.
Epidermal barrier recovers within 24 hours while dermal collagen remodeling continues for months. Dermapen 4 uses 16 33G needles at 120 punctures/second.
Mechanism of Action
Needles penetrating the dermal-epidermal junction activate platelets releasing PDGF, TGF-β, and FGF. This activates fibroblasts to produce type I/III collagen. Three-phase wound healing (inflammation → proliferation → remodeling) forms mature collagen network over 6-12 months.
Indications
Expected Results
25-50% improvement in acne scars after 3-6 sessions. 2-4 sessions for pores and texture. Results apparent at 1-3 months, peak at 6-12 months.
