Compared to Fractional RF, whose energy just reach epidermis, so can’t treat wrinkles and scar problem in dermis. Needles don’t contact skin to operate, not be influenced by skin resistance.
Compared to Fractional laser, Mjolnir’s investment cost is much more economical, but can cover all the application of laser. Safety risk to operator and patient both are much lower, and can be used more widely, no any medical limits.
Compared with normal plasma, whose current excitation is performed at a lower frequency, and the plasma column has poor directivity and low power. Single plasma’s treatment needs much longer time, the energy is difficult to control, un-even treatment depth, and dots’ consistency is poor, so more dangerous and bigger damage risk to skin.
