Explore permanent hair reduction technologies including laser hair removal, IPL, and electrolysis. Learn the science behind effective and safe hair removal treatments.
What is Hair Removal Energy?
Hair removal energy technologies use various forms of energy to target and destroy hair follicles, preventing future hair growth. The three main approaches are laser technology (targeting melanin), IPL (broad-spectrum light), and electrolysis (direct electrical current).
Each technology works differently: lasers use selective photothermolysis to target melanin in hair follicles, IPL uses broad-spectrum light for multiple targets, and electrolysis uses direct current to destroy individual follicles. Understanding these differences is crucial for optimal treatment selection.

Skin Type Considerations
Fitzpatrick I-II
Very fair to fair skin
Recommended:
All laser wavelengths, especially 755nm and 1064nm
Considerations:
Lower risk of side effects, may require higher fluence
Fitzpatrick III-IV
Medium to olive skin
Recommended:
755nm, 810nm, and 1064nm wavelengths
Considerations:
Moderate risk, requires careful parameter selection
Fitzpatrick V-VI
Dark to very dark skin
Recommended:
1064nm Nd:YAG laser only
Considerations:
Higher risk of side effects, requires experienced practitioner
