Zein. Selting & Hamblin (2018) reviewed the studies on laser particularly looking at energy and power. They stated some simple principles found throughout the literature:
Different tissues can be divided into different categories for laser
- Higher numbers of mitochondria (muscle, inflammatory cells, nerve)
- = Susceptible to over-dosing
- Lower numbers of mitochondria (skin, tendon, cartilage, bone)
- = Less susceptible to over-dosing
“Although the results showed a high degree of variability. Ineffective studies in cells with high mitochondrial activity appeared to be more often due to over-dosing than to under-dosing.”
