Wavelength decides who you can treat
A laser emits one coherent wavelength; IPL emits a filtered band. That single difference drives skin-type safety, treatment speed, consumable cost and the fluence you need.
Output compared, 600–1100 nm
Strong melanin absorption, fast clearance on fine and light hair. Not the first choice for deeper phototypes.
The general-purpose wavelength. Good depth, high repetition rates, large applicators for in-motion work.
Deeper penetration than 808 nm with lower epidermal absorption. Usually blended in a platform rather than sold alone.
Lowest melanin absorption, so the safest option on deep skin. Needs higher fluence and effective cooling.
