Laser Energy Absorption: Nd:YAG laser emits light specifically absorbed by tattoo pigment.
Heat Induction: This absorbed energy heats pigment particles, causing them to fragment.
Immune Response: Immune cells engulf and remove fragmented pigment particles.
Fading Process: Over multiple sessions, the body gradually clears the pigment, leading to tattoo fading.
Considerations: Factors like pigment color, depth, and skin type affect treatment effectiveness.
