Both IPL and diode laser devices rely on the pigment of the hair follicle to lessen or completely remove it from your skin, but diode lasers are generally more precise, making them a safer option for most skin types and tones.
However, it's important to use caution when trying out any at-home laser hair removal device. Those with lighter hair or darker skin should carefully consider their options regarding their tool of choice. Karavolas notes that the preferred type of wavelength to use on skin of color in professional laser treatments is about NDYAG 1064 nm.
"I recommend that my clients first test spots in less conspicuous areas, like the arms or legs, to see if burning or hyperpigmentation occurs before proceeding to treat the face or more prominent areas of the body," Anthony Rossi, a dermatologist and Mohs surgeon at Memorial Sloan Kettering Cancer Center in New York City, says.
Having more pigment in your skin may confuse the laser, Zeichner cautions, leading to discoloration in the skin. "In general, at-home laser hair removal devices are not optimal for those with sensitive skin or skin of color as the potential risk of irritation, hyperpigmentation, or scarring is increased," Garshick adds. "For individuals with sensitive skin and darker skin types, it's especially important to ensure the selected device is appropriate and should always be discussed with a board-certified dermatologist prior to use."
