The primary difference between Galvanic and Thermal electrolysis lies in the method they use to destroy the hair follicle: Galvanic employs a chemical reaction, while Thermal uses heat.
Both are methods of permanent hair removal performed by inserting a fine probe into the hair follicle. However, their mechanisms of action differ significantly.
Galvanic Electrolysis
Galvanic electrology creates its effect by converting moisture in the follicle into caustic lye. This lye is a chemical substance that chemically breaks down the walls and structure of the hair follicle, effectively destroying it and preventing future hair growth.
- Method: Chemical process
- Mechanism: Converts moisture into caustic lye
- Action: Chemically breaks down follicle tissue
- Energy Source: Direct Current (DC)
This method involves a slower chemical reaction compared to thermal methods, often requiring more time per follicle.
Thermal Electrolysis (Thermolysis)
In contrast, thermolysis relies on heating the moisture within the hair follicle to the point of electrocoagulation. This process uses high-frequency alternating current to generate heat very rapidly at the tip of the probe, essentially "cooking" and destroying the follicle tissue.
- Method: Heat process
- Mechanism: Heats moisture to electrocoagulation
- Action: Destroys follicle tissue through heat
- Energy Source: Alternating Current (AC) / Radiofrequency
Thermolysis is generally much faster than the galvanic method due to the rapid heat generation.
Key Differences at a Glance
Here is a table summarizing the core distinctions:
| Feature | Galvanic Electrolysis | Thermal Electrolysis (Thermolysis) |
|---|---|---|
| Mechanism | Chemical decomposition | Heat coagulation |
| Agent | Caustic Lye (created from moisture) | Heat (generated from electrical current) |
| Action | Chemically breaks down follicle walls | Thermally destroys follicle tissue |
| Current Type | Direct Current (DC) | Alternating Current (AC) / Radiofrequency |
| Speed | Generally slower | Generally faster |
Understanding these differences is crucial for appreciating the specific techniques used in permanent hair removal procedures.
