     It is also important to avoid getting a sun tan over the tattoo lesion. UV rays increases epithelial melanin which may interfere with Laser therapy and increase the risk of hypopigmentation and hyperpigmentation. If the skin is already tanned or sunburned, it is best to delay the treatment until the sunburn is resolved.  


     Oral retinoids taken within the past 12 months of treatment can also increase the risk of scarring as it interferes with wound healing. Herpes infection on or near the treatment area is another contraindication. In patients with history of herpes infection, preventive oral antibiotics can be used along with the removal treatment.



    Laser Selection

     In general, the Q-switched alexandrite Laser(755nm), Q-switched ruby Laser(694nm), or Q-switched Nd:YAG Laser(1064nm) is used in black to dark gray tattoos. However, Lasers with a longer wavelength is advised in patients with Fitzpatrick type IV – VI in order to reduce damage to the epidermis. I use the Q-switched Nd:YAG Laser(1064nm) as the primary choice in black and dark tattoo ink.  

     The Q-switched ruby Laser(694nm) is suitable in green tattoo ink and Q-switched Nd:YAG Laser(532nm) in red ink. However, caution is advised in patients with a darker skin tone due to a raised risk of hypopigmentation and hyperpigmentation.

    Laser Tattoo Removal Process


     Depending on the patient conditions and lesion type, the pulse duration of Laser can cause various degrees of pain from instantaneous pain, deep, cutting pain, and burning sensation. Topical anesthetic cream or subcutaneous injection is used for anesthesia. For tattoo removal over an extensive area, general anesthesia can be carried out.
