What is the best laser for dark skin?
A 1064nm Nd:YAG laser is the best choice for dark skin. Melanin absorbs 1064nm weakly, so energy reaches the follicle without overheating a heavily pigmented epidermis. Pair it with long pulse widths, conservative starting fluence, sustained contact cooling and a 24-hour patch test.

Why wavelength decides this
Melanin absorption falls as wavelength rises. At 755nm, epidermal melanin competes strongly with the hair shaft for energy, which on Fitzpatrick V–VI produces burns and post-inflammatory hyperpigmentation. At 1064nm that competition is far weaker, so the same fluence deposits proportionally more of its energy at the follicle.
This is a physical constraint, not a technique one. No amount of operator skill makes 755nm the right primary wavelength for Fitzpatrick VI.
The protocol that goes with it
Patch test at intended settings at least 24 hours ahead. Start below your expected working fluence and step up across sessions based on response, never within a single visit. Use the longest practical pulse width. Maintain contact cooling at or below 0°C through the whole pass, and verify the machine holds that temperature during a long in-motion pass rather than only on the first shot.
What about IPL?
IPL should not be used on Fitzpatrick VI. Broadband output deposits too much energy in a pigmented epidermis regardless of filter choice. With long pulse durations and conservative fluence, trained operators use IPL up to Fitzpatrick IV.
