The Q-switched Alexandrite laser is a specific type of laser used for various dermatological procedures, including tattoo removal. Here are some key points about the Q-switched Alexandrite laser:
The Alexandrite laser emits light at a wavelength of 755 nanometers, which corresponds to the red part of the electromagnetic spectrum.
The term “Q-switched” refers to the ability of the laser to produce short bursts of high-energy pulses. This rapid and intense energy delivery is crucial for effectively breaking down tattoo pigments. Alexandrite lasers are generally more effective on lighter skin tones. However, advancements in technology have led to the development of lasers with adjustable parameters to cater to a broader range of skin types, including ethnic skin types.
Q-switched Alexandrite lasers are particularly effective in targeting dark pigments, such as black and dark blue ink, commonly found in tattoos. The short pulses of high energy can shatter the ink particles into smaller fragments.
The principle behind Q-switched laser tattoo removal is called selective photothermolysis. This means that the laser energy selectively targets the tattoo pigment while minimizing damage to surrounding skin tissues.
Just like other lasers are typically used in a series of treatment sessions for tattoo removal. These sessions are spaced several weeks apart to allow the body to naturally eliminate the fragmented ink particles.
Common side effects of Q-switched Alexandrite laser tattoo removal may include redness, swelling, and temporary changes in skin pigmentation. These effects are usually transient and part of the natural healing process.
In addition to tattoo removal, Q-switched Alexandrite lasers are used for various dermatological procedures, including treatment of pigmented lesions, age spots, and certain types of birthmarks.
Before undergoing any laser tattoo removal procedure, it’s essential to consult with Dr Kormeili who can assess your individual case, skin type, and the specific characteristics of the tattoo. We can provide personalized advice and determine the most suitable laser and treatment plan for your needs.
