This is an important question but has not been properly studied clinically (to my knowledge). When my research group first developed the Q-switched ruby laser treatment of tattoos in Canniesburn Hospital, Glasgow, in the early 1980s they established that a minimum four-week period was the optimum time between repeat laser sessions. This became the standard… Continue reading How long should you leave between laser tattoo removal treatments?
The ‘standard’ definition of penetration depth in skin only considers the incident wavelength and optical properties of the skin. While this may be useful from a physics perspective, it is not particularly useful when considering clinical treatments. A more useful definition must include wavelength, anisotropy, spot diameter and incident fluence. All of these have an… Continue reading Laser-IPL Penetration Depth – a more useful definition
