What happens to target tissues when chromophores absorb laser energy?

When chromophores absorb laser energy, the target tissues can undergo significant changes depending on the amount and type of energy absorbed. Chromophores are molecules within the tissues that are capable of absorbing specific wavelengths of light, including those produced by lasers. The absorption of laser energy by these chromophores leads to various thermal effects in the target tissues, such as heating, photochemical reactions, or other biological processes.

These changes can result in various outcomes, including tissue alteration, remodeling, or even destruction if the energy level is sufficiently high. For instance, in medical or aesthetic procedures, this mechanism is often utilized to target and treat specific areas, allowing for controlled outcomes like tissue tightening or scar reduction. The precise response varies with the chromophore type, the energy delivered, and the duration of exposure, making this interaction crucial for effective laser therapies.
