Fractional RF Depth Guide: Choosing the Right Cartridge

Fractional RF uses micro-needles to deliver radiofrequency energy into precise skin layers. Choosing the right needle depth improves treatment results, reduces downtime, and minimizes risk. This guide helps beauty clinics match cartridges to common indications and patient needs.

Why Depth Selection Matters

Each cartridge controls needle penetration, targeting different skin layers:

• superficial (epidermis)

• mid-dermis

• deep dermis + subcutaneous tissue

Selecting an appropriate depth ensures controlled coagulation and collagen remodeling without overtreatment.

Recommended Needle Depths for Common Concerns

Choosing the Right Depth by Treatment Area

Face

• peri-orbital areas: 0.5–1.0 mm

• cheeks: 1.5–2.5 mm

• jawline tightening: 2.5–3.5 mm

Neck + décolleté

• avoid aggressive deep passes

• recommended: 1.0–2.0 mm

Body

• abdomen or thighs with laxity: 2.5–3.5 mm

Dual-pass Layering Technique

Clinics often combine depths for enhanced results:

1. first pass at deeper level for tightening

2. second pass at shallow depth for texture refinement

This reduces trauma while maximizing collagen stimulation.

Patient Comfort & Safety Tips

• lower energy for thinner/sensitive skin

• use insulated needles when treating near bony areas

• apply topical anesthetic before treatment

• avoid excessive overlap of shots

• consider contraindications such as pregnancy or metal implants

Conclusion

Fractional RF outcomes depend heavily on selecting the right cartridge depth. By matching penetration levels to treatment zones and indications, clinics can achieve optimal collagen induction while minimizing discomfort and downtime. A structured, layer-specific approach helps deliver predictable, safe, high-value results.
