What happens to the tissue during absorption of laser energy?

When laser energy is absorbed by tissue, a fundamental reaction occurs that leads to structural changes within the cells and extracellular matrix. This absorption of energy causes molecular bonds to break, leading to alterations in the chemical structure of the tissue components.

In particular, the energy from the laser can result in processes such as denaturation of proteins, which changes their structure and function. This transformation is crucial in various medical applications, such as in laser surgery where precise cutting and tissue shaping are required. Additionally, the changes can also promote healing responses or the desired effects in therapeutic applications.

While vaporization of the tissue can occur at certain energy levels, and cooling or reflection might take place under different circumstances, the key effect of absorbed laser energy is indeed the structural change in the tissue itself. This understanding is essential for effectively utilizing laser technology in medical and aesthetic procedures.
