The Sterex Insulated Two‑Piece F4I Short Needles (50PCS) are premium electrolysis needles engineered for exceptional precision, comfort, and skin protection. Manufactured from medical‑grade stainless steel and coated with a specialist insulation material, these needles deliver targeted energy directly to the follicle while shielding the surrounding skin from unnecessary heat exposure.
The insulated coating releases current only from the tip, making these needles ideal for sensitive skin types and clients who are more prone to hyper‑pigmentation. This includes Afro‑Caribbean and Asian skin tones, where minimizing surface trauma is especially important. The result is a smoother, safer treatment experience with reduced irritation and improved post‑treatment appearance.
The F4I Short size is designed for treating fine to medium hairs in areas requiring shallow insertions. The two‑piece construction provides excellent rigidity and smooth insertion, giving electrologists superior control and consistent performance. These needles are intended exclusively for Short Wave Diathermy, ensuring optimal precision and treatment efficiency.
Trusted by professional electrologists worldwide, Sterex insulated needles deliver reliable, high‑quality results with every use.
