How does laser tattoo removal work
In: Biology
Different colors absorb different wave lengths of light. The laser is set to one of these wave lengths (1064nm for black, 755nm for free, and 532nm for red are the best). The pigment in the tattoo absorb the light, heat is created, and it explodes the pigment within the cell. Your body is already working to remove these foreign bodies anyway (which is why tattoos fade over time anyway) but now that the foreign bodies are much smaller (having been exploded), they are much easier to remove. So your white blood cells are removing the foreign bodies and you excrete them as you would anything else.
Black is the easiest color to remove (black absorbs all wavelengths, same reason a black car gets hottest in summer). Blue next. Green is the toughest. Professional tattoos are more predictable than amateur ones as the pigment is inserted at a consistent level within the skin. You should space out treatments significantly, allowing your body plenty of time to do it’s thing. Doctors that bring you back once/month are just trying to get more money out of you. Every three months, max.
Tattoos on your core go away faster than on your extremities. More blood flow in your core so it can be excreted faster.
