Q-Switched Alexandrite Laser Tattoo Removal in Nairobi, Kenya

Q-Switched Alexandrite Laser Tattoo Removal Overview

• Wavelength and Melanin Absorption:
  – The Alexandrite laser emits light at a wavelength of approximately 755 nanometers.
  – This wavelength is well-absorbed by melanin, the pigment present in both the tattoo ink and the skin.
• Selective Photothermolysis: The principle of selective photothermolysis is applied, where the laser energy is selectively absorbed by the tattoo pigments while minimizing damage to the surrounding skin.
• Pulse Duration:
  – The Q-switching technique allows the laser to produce very short pulses in the nanosecond range.
  – The short pulse duration is crucial for effectively breaking down the tattoo ink into smaller particles without causing excessive heat buildup in the skin.
• Ink Fragmentation:
  – The laser energy is delivered to the tattooed area, and it is absorbed by the ink particles.
  – The intense, short-duration pulses cause a photomechanical effect, where the rapid heating and cooling of the tattoo pigments lead to their fragmentation into smaller particles.
• Body’s Natural Removal Process:
  – The fragmented ink particles are smaller and can be more easily engulfed by immune cells.
  – Over time, the body’s natural processes, such as phagocytosis, work to eliminate these smaller ink particles through the lymphatic system.
• Multiple Sessions:
  – Tattoo removal using Q-Switched Alexandrite lasers typically requires multiple sessions.
  – Sessions are spaced several weeks apart to allow the body to process and eliminate the fragmented ink particles between treatments.

The effectiveness of tattoo removal can vary based on factors such as the type and color of the tattoo ink, the depth of the ink in the skin, and the individual’s skin type. Darker pigments, such as black and blue, tend to respond more effectively to laser treatment.

Here are the key features and applications of the Q-switched Alexandrite laser:

• Gain Medium: The active medium in a Q-switched Alexandrite laser is a synthetic crystal made of alexandrite, which is a form of chrysoberyl that contains chromium ions. The crystal produces laser light at a wavelength of approximately 755 nanometers, falling within the red and near-infrared range of the electromagnetic spectrum.
• Pumping Mechanism: Similar to the Q-switched ruby laser, the Alexandrite crystal is pumped using a flashlamp, often made of xenon. The flashlamp delivers energy to the crystal, causing the chromium ions to transition to higher energy states and emit laser light.
• Q-Switching: Q-switching is a technique employed to produce short and high-intensity pulses of laser light. In the case of the Q-switched Alexandrite laser, the Q-switching mechanism allows for the accumulation of energy within the gain medium followed by a rapid release, resulting in short pulses.
• Short Pulse Duration: One of the advantages of Q-switched Alexandrite lasers is their ability to generate very short pulses, typically in the nanosecond range. This characteristic is valuable in medical and cosmetic applications where precise targeting and minimal thermal damage to surrounding tissues are essential.
• Applications:
  – Hair Removal: Q-switched Alexandrite lasers are commonly used for laser hair removal. The wavelength of around 755 nm is well-absorbed by melanin, the pigment in hair follicles, making it effective for hair removal in various skin types.
  – Pigmented Lesions: The laser is used for the treatment of pigmented lesions such as age spots, sunspots, and freckles.
  – Tattoo Removal: Q-switched Alexandrite lasers can also be utilized for tattoo removal by breaking down the tattoo ink into smaller particles that the body can eliminate.

Q-Switched Alexandrite Laser Tattoo Removal Process

• Consultation:
  – Before the procedure begins, at Rebel Inks Tattoos, Tattoo Removal, and Body Piercings Parlour, you’ll have a consultation with one of our qualified laser professionals.
  – During the consultation, your skin type, the characteristics of the tattoo, and your medical history will be assessed to determine the suitability of the Q-Switched Alexandrite laser for your specific case.
• Preparation:
  – The area to be treated will be cleaned, and a topical anesthetic may be applied to minimize discomfort during the procedure.
  – You may be provided with protective eyewear to shield your eyes from the laser light.
• Parameter Adjustment: The healthcare professional will adjust the laser settings, including the wavelength and pulse duration, based on the characteristics of your tattoo and skin.
• Laser Application:
  – The Q-Switched Alexandrite laser will be directed at the tattooed area, and short pulses of high-intensity light will be delivered to the skin.
  – The laser energy is selectively absorbed by the tattoo pigments, causing them to fragment into smaller particles.
• Immediate Response:
  – You may experience a snapping or stinging sensation during the laser pulses. Some discomfort is normal, but the use of a topical anesthetic helps manage this sensation.
  – Immediate whitening or frosting of the treated area may occur, which is a temporary reaction to the laser energy.
• Post-Treatment Care:
  – After the laser treatment, a cooling agent or soothing gel may be applied to the treated area to alleviate any discomfort and reduce redness.
  – You will receive specific post-treatment care instructions, including guidelines on sun protection and avoiding certain activities that may irritate the treated skin.
• Follow-up Sessions:
  – Tattoo removal is typically not achieved in a single session. Multiple sessions, spaced several weeks apart, are usually required to allow the body to eliminate the fragmented ink particles.
  – The number of sessions needed depends on factors such as the size, color, and depth of the tattoo.
• Monitoring Progress: Your healthcare professional will monitor the progress of the tattoo removal during follow-up appointments and may adjust the laser settings if needed.
