Skin Tightening (PIANO® Mode)

This treatment leverages Fotona's patented PIANO® mode, which delivers super-long Nd:YAG laser pulses in the seconds regime—well beyond the thermal relaxation time of the outer skin layer. This unique method avoids high temperature peaks on the skin surface, instead driving safe, homogeneous "bulk heating" (42.5°C to 43°C) deep into the dermal tissues. This controlled thermal environment triggers immediate contraction of loose collagen fibers while stimulating protective heat shock proteins, kicking off a long-term healing cascade (neocollagenesis) to gradually lift, tighten, and firm loose or saggy skin.
