What is one important factor to assess before performing laser tattoo removal?

One important factor to assess before performing laser tattoo removal is the colors of the tattoo ink. Different ink colors absorb laser energy differently, which significantly affects the effectiveness of the removal process. Lasers are specific to certain wavelengths of light; for example, black ink can absorb a wide range of wavelengths, making it easier to remove. However, colors like green or light blue require specific lasers, as they do not respond as well to the same wavelengths suitable for darker inks. Understanding the colors used can help the practitioner choose the appropriate laser and settings, ensuring a more effective treatment and minimizing the risk of skin damage or incomplete removal.
