RF Microneedling Depth & Needle Guide
RF microneedling depth is adjustable from 0.5 to 3.5mm and should match the treatment area: 0.5–1.0mm for peri-orbital and delicate skin, 1.5–2.5mm for full-face rejuvenation and acne scars, and 2.5–3.5mm for stretch marks and body tightening. Correct depth — not just power — is what separates safe, effective results from complications.
Depth by indication
Eyes/neck: 0.5–1.0mm. Full face/scar: 1.5–2.5mm. Stretch marks/body: 2.5–3.5mm. Always start shallow and increase by tolerance.
Needle configuration
Non-insulated needles heat deeper; partially insulated concentrate energy at the tip for superficial work. Choose handles that let you vary both depth and energy per zone.
Safety essentials
Sanitised single-use tips, topical anaesthetic for deeper settings, post-care recovery cream, and sun protection. Avoid active acne or active infection areas.
