What is 'line (kJ)' in Onda Lifting? Is it different from the number of shots?

Procedures like Ultherapy or Serf typically calculate in 'shots', but Onda indicates the total amount of energy delivered in 'Joules'. For example, 60,000 Joules (60kJ), 100,000 Joules (100kJ), etc. Having a high number of Joules does not necessarily mean it is better; it is more important to design the appropriate amount based on skin condition and goals (whether it focuses more on collagen stimulation or fat reduction).
