Modality Application and Technique (Galvanic, Thermolysis, Blend)
Technique fundamentals
Correct insertion follows the hair shaft angle into the follicle without puncturing the skin or bending the needle. Insertion depth should reach the bulb region appropriate to the site. Current is applied for a controlled duration, then the hair is removed with minimal traction.
Galvanic requires a dispersive electrode and sufficient time for lye to form; it is slower but effective for curved or distorted follicles. Thermolysis is faster but relies on precise timing; too much energy causes blanching, pitting, or scarring. Blend balances both: lower galvanic current plus thermolysis heat, often used for coarse or distorted hairs.
Traps in questions
- Never force a hair; resistance suggests poor insertion or wrong angle.
- Over-treatment signs include blanching, excessive erythema, and tissue crusting.
- Needle size should match hair diameter; too large a needle increases trauma.
- Settings are individualized, not copied from a chart.
Rule of thumb
"Insert gently, treat precisely, remove without traction." If the hair does not release easily, the follicle was likely under-treated; increase treatment appropriately rather than pulling.
