Alexandrite Q-Switched Laser

The Alexandrite laser uses a 755 nm wavelength that is strongly absorbed by melanin and certain tattoo pigments. Our Q-Switched Alexandrite laser can treat brown spots, sun spots, freckles, café-au-lait macules, selected birthmarks, and certain forms of hyperpigmentation. It is also used for tattoo and permanent makeup removal, especially when black, blue, or green pigment is present. Short, high-energy pulses break pigment into smaller particles that your body gradually clears.
A typical Q switch laser treatment takes about 5 to 30 minutes, depending on the number and size of treated areas. We may apply numbing cream or inject local anesthetic for tattoos and permanent makeup. Protective eyewear is worn during treatment. Immediately after the laser pulse, the treated pigment often develops temporary whitening or “frosting,” followed by redness or darkening.
Dr. Rokhsar selects treatment settings after examining your skin tone, pigment depth, and diagnosis. Brown spots and freckles may need fewer sessions than tattoos. Conditions such as melasma require more caution because heat and inflammation can sometimes worsen pigmentation. For some patients, another laser or a combined treatment plan is more appropriate. Sessions are spaced to allow the skin to heal and pigment particles to clear between visits.

At the New York Cosmetic, Skin & Laser Surgery Center, Q switch laser NYC treatments are performed under the direction of Dr. Cameron Rokhsar. He is double board-certified in dermatology and micrographic dermatologic surgery and fellowship-trained in laser surgery. Dr. Rokhsar was involved in developing Fraxel laser technology and has conducted research involving several laser and energy-based systems.
Dr. Rokhsar completed his undergraduate education at Harvard College and earned his medical degree from NYU School of Medicine. He is an Associate Clinical Professor of Dermatology at Mount Sinai Hospital and has trained physicians in cosmetic dermatology and laser procedures. Our Manhattan office at 121 East 60th Street offers the Alexandrite laser NYC for carefully selected pigment and tattoo concerns.
Choosing between a Q-Switched Alexandrite laser and a picosecond device such as PicoSure or PicoWay depends on the target. The 755 nm Alexandrite wavelength has strong absorption by melanin and certain dark, blue, and green tattoo pigments. Pico lasers can also be useful for tattoo and pigmentation treatment. Dr. Rokhsar selects the device based on pigment color, depth, skin tone, prior treatment, and clinical diagnosis rather than using one laser for every patient.
Good candidates may include patients seeking laser pigmentation removal NYC treatment for freckles, sun spots, age spots, selected birthmarks, or unwanted tattoos. Darker skin requires careful laser selection because pigment changes can occur after treatment. Dr. Rokhsar may perform a test spot or recommend a different wavelength when appropriate. Our facilities are Quad A accredited, and each treatment plan is based on your individual skin and pigment characteristics.
* Results May Vary.

Results from the Q switched Alexandrite laser appear gradually as treated pigment clears. Brown spots often darken first, then flake or fade during the following one to two weeks. Some discrete sun spots respond after one treatment, while other lesions require additional sessions. Your response depends on pigment depth, location, skin type, and the condition being treated.
Tattoo and permanent makeup results develop more gradually. Each session breaks additional pigment into smaller particles for the body to remove. Tattoo color, ink density, depth, age, and location affect the number of treatments required. Black, blue, and green inks may respond well to the Alexandrite wavelength, although some tattoos require another laser wavelength for complete treatment.
Results from laser pigmentation removal NYC treatment can be long lasting when the targeted pigment clears. However, new sun spots can develop after future ultraviolet exposure, and conditions such as melasma can recur. Daily sun protection helps reduce new discoloration. Tattoo ink that has been successfully cleared does not regenerate, although complete removal cannot be guaranteed for every tattoo.
Downtime after a Q switch laser treatment is usually limited, but the healing response depends on what we treat. Brown spots commonly become white immediately after treatment, then turn darker before flaking away. Redness and mild swelling can occur. Tattoo and permanent makeup treatment may cause more swelling, crusting, or occasional blistering during the early healing period.
After treatment, we give you instructions based on the treated area. You may need to apply ointment and keep tattoo sites covered with a clean dressing. Avoid picking crusts or scabs because this can increase the chance of pigment changes or scarring. Many treated brown spots heal within one to two weeks, while tattoo sites can take longer.
Potential side effects include temporary hyperpigmentation, hypopigmentation, redness, swelling, blistering, and uncommon scarring. Patients with darker skin may have a higher risk of pigment change with melanin-targeting wavelengths. A test spot or different laser may be recommended. Dr. Rokhsar’s fellowship training in laser surgery helps him select settings based on your skin tone, diagnosis, and treatment history.
