GentleMax Pro Plus and LightSheer Quattro sit in the same hair removal lasers category but take different approaches. GentleMax Pro Plus (Candela (Syneron)) uses Dual-Wavelength Alexandrite (755nm) + Nd:YAG (1064nm) while LightSheer Quattro (Lumenis) uses High-Speed Diode Laser (805nm, 1060nm dual wavelength). Both received FDA clearance (2020 and 2021 respectively) and both are actively sold in the US market. The decision between them is rarely about which is objectively better. It's about which fits your specific practice.
Physicians end up comparing these two devices when they're shopping in the $115,000-$175,000 to $90,000-$140,000 price range and want a category leader. Both devices are commonly recommended by sales reps from competing manufacturers, which means physicians often hear inflated claims about one and dismissive claims about the other. This comparison strips out the marketing and looks at pricing, mechanism, evidence, and practice fit side by side.
Technology: Dual-Wavelength Alexandrite (755nm) + Nd:YAG (1064nm). Dual-wavelength platform combining 755nm Alexandrite (fastest hair removal wavelength on fair to medium skin) and 1064nm Nd:YAG (only wavelength with adequate depth for Fitzpatrick V-VI) in one console. The 27mm spot size is the largest in the laser hair removal category as of 2026, reducing treatment time on back and leg areas by 30-40% versus 18mm competitors. Dynamic Cooling Device (DCD) sprays cryogen 30ms before each pulse, which is what allows the high fluences needed for permanent hair reduction while managing epidermal thermal damage. Clinical training and service are available at any of Candela's four US service centers.
LightSheer Quattro
