When you change a laser parameter you should ask yourself a number of questions:
1. How does this affect the depth of penetration? (wavelength, spot size, energy density)
2. Will it affect the absorption in the ink (colour, wavelength)?
3. How will it affect the absorption in the melanin layer? Or the capillary plexus?
4. Will a higher fluence/energy density adversely affect the dermis? Or the epidermal
melanin?
Laser parameters must be chosen to maximise efficiency according to the tattoo ink colour, depth and location and the patient's skin colour.
Clearly, it is important to understand how varying one parameter affects the result. This can only be done if we understand how each individual parameter changes the outcome.
Hope this helps. Mike.
