Q-switched lasers are often used for tattoo removal services. Optimal results can be promoted by:
- Assessing the tattoo’s size, colour, ink type and ink depth
- Choosing a suitable Q-switched laser
- Targeting ink pigments using laser wavelengths
Q-Switched Laser for Tattoo Removal
Q-switched lasers are a type of laser technology commonly used for tattoo removal. They work by emitting short, high-energy pulses of light that are absorbed by the tattoo ink. The energy from the laser breaks the ink into smaller particles, which are then naturally absorbed and eliminated by the body.
Treatments with a Q-switched laser are typically performed in a series of sessions, with each session spaced several weeks apart. The number of treatments required can vary depending on several factors, including the size and location of the tattoo, the depth of the ink, and the individual’s skin type.
Q-switched laser tattoo removal is considered to be a safe and effective method for removing tattoos. However, as with any medical procedure, there is a risk of side effects, including pain, blistering, scarring, and changes in skin colour. Dr Yip is qualified to perform this service, and implements safety measures to reduce the likelihood of adverse medical and cosmetic effects.
There are several different types of Q-switched lasers that can be used for tattoo removal, including Q-switched Nd:YAG lasers, Q-switched alexandrite lasers, and Q-switched ruby lasers. The type of laser used for tattoo removal will depend on the colour of the tattoo ink, as well as the individual’s skin type.
Q-Switched ND:YAG Laser
NP:YAG stands for “neodymium-doped yttrium aluminum garnet”. Light is emitted from this laser via two wavelengths: 532nm and 1,604nm. The former allows for the removal of warmer colours such as yellow, orange, red, pink, brown and white. The higher wavelength is absorbed by dark-coloured tattoo inks, such as black, purple and blue. The pulse duration is 5-10ns, the repetition rate is approximately 10 Hz, and there is a 1.5-8mm spot size.
Q-Switched Ruby Laser
Light is emitted from this laser at a 694nm wavelength. The pulse duration is 28-40ns. This laser is usually used to removal unusual tattoo colours, including turquoise and lime green. Resistant ink shades are also removed using the Q-switched ruby laser.
Q-Switched Alexandrite Laser
The Q-switched alexandrite emits light at a 755nm wavelength. This laser has a 50-100ns pulse duration, 2-4mm spot size, and a 10Hz repetition rate. Usually, this laser is used after ND:YAG laser treatment to remove any remaining dark green
