The skin is our largest organ and reflects both our health and our lifestyle. As we age or due to sun exposure, changes can occur that affect the appearance of the skin. Tattoos can also go out of style over time or become a source of discomfort in one’s personal life or professional setting. This can lead to a desire to have the tattoo removed.

At ROC Derma, your private dermatology practice in Aschheim near Munich, the focus is on providing the highest standard of aesthetic and medical skin care. With the introduction of the NanoStar® R laser, the practice is expanding its range of services to include state-of-the-art laser therapy, which enables the effective, precise, and gentle treatment of tattoos and pigmented skin lesions. The system complements ROC Derma’s existing services and sets new standards in skin treatment, as it is both medically sound and patient-friendly.
In this in-depth article, you’ll learn everything about how the NanoStar® R laser works, its applications for tattoos and pigmented lesions, the treatment process, aftercare, potential risks, and the scientific background.
The NanoStar® R laser is an innovative laser system based on ultrashort light pulses in the nanosecond range. This technology is specifically designed to selectively break down pigments in the skin without damaging the surrounding tissue. The laser energy is absorbed by the pigment particles, causing them to break down into tiny fragments, which are then naturally eliminated by the body via the lymphatic system. This procedure allows for highly precise treatment of tattoos and pigmented lesions while minimizing stress on the skin.
The laser’s wavelength is optimally tailored to different types of pigment. Dark pigments, such as black or blue tattoo ink, absorb the laser energy safely and efficiently. For patients, this means that each treatment is planned individually and tailored to their skin type, pigment color, and depth.
The laser works on the principle of selective photothermolysis, in which the laser energy is specifically absorbed by the pigment while the surrounding tissue remains unharmed. The pulse duration, measured in nanoseconds, ensures that the energy acts precisely on the pigments without causing thermal damage to the skin. Thanks to this precision, tattoos of any size and pigment color can be effectively treated, while the skin’s recovery time remains minimal.
Tattoo removal is one of the main applications of the NanoStar® R laser. At the ROC Derma clinic in Aschheim, both black and blue tattoos can be treated.
The effectiveness of the treatment depends on various factors, including the color and intensity of the tattoo, the age of the tattoo, the depth of the pigment in the skin, the size of the tattooed area, and the individual’s skin type. Every tattoo is unique, which is why the treatment is planned in close consultation with the treating dermatologist, Dr. Horváth. Before treatment begins, a comprehensive dermatological consultation is conducted to discuss potential risks, the number of sessions required, and the expected results.
A typical treatment involves several steps. First, the treating physician analyzes the tattoo and the skin. The patient is then given a detailed explanation of the treatment process, the expected results, and possible side effects. During the treatment, the NanoStar® R laser is applied with pinpoint precision to the tattoo pigments, while the skin is continuously cooled to minimize redness and swelling. After the session, the skin is treated, cooled, and special ointments or bandages are applied. Consistent aftercare with sunscreen and skin care is crucial to achieving optimal results.
Most patients require between four and ten sessions to achieve satisfactory results. Sessions are typically spaced four to eight weeks apart to give the body enough time to break down the destroyed pigments. Larger, deeper, or particularly colorful tattoos may require more sessions.
In addition to tattoos, the NanoStar® R laser can also be used to treat pigmented spots. The treatment is based on the same principle as for tattoos: the laser energy is specifically absorbed by the pigments, causing them to break down into small particles that are then eliminated by the body via the lymphatic system. The surrounding skin remains unharmed, making the treatment particularly gentle on the skin. Through multiple sessions, an even, healthy complexion can be achieved that highlights the skin’s natural beauty.
Patients often report that their skin appears significantly brighter and more even-toned after treatment. The treatment is particularly suitable for sensitive areas such as the face, hands, or décolletage, as it can be performed on an outpatient basis and causes minimal stress to the skin. In most cases, two to three sessions are sufficient to achieve noticeable results.
The success of laser treatment depends largely on the Fitzpatrick skin type. Fair-skinned patients (types I and II) respond very well to laser therapy and have a low risk of pigment changes. Patients with medium skin types (III and IV) may require adjusted treatment intervals to achieve optimal results. Darker skin types V and VI require special caution, as the risk of hyper- or hypopigmentation is increased in these cases. The treating physicians at ROC Derma adjust the laser parameters individually to ensure both safety and effectiveness.
Aftercare following laser treatment is crucial to the success of the procedure. Immediately after the session, the skin should be cooled to reduce redness and swelling. Mild redness and blistering are normal reactions that subside within a few days.
In the weeks following treatment, the treated skin areas should be consistently moisturized with hydrating creams and protected from sunlight. Sunscreen with a high sun protection factor (SPF 50+) is particularly important to prevent pigmentation issues. Aggressive cosmetics or self-tanning products should be avoided. In the long term, it is recommended to regularly monitor the treated areas and consult with the treating physician if any abnormalities are noticed.
Laser treatments have been thoroughly clinically studied and are considered a safe, effective method for removing tattoos and pigmented lesions. Selective photothermolysis makes it possible to specifically target and break down pigments without damaging the surrounding tissue. Nanosecond lasers, such as the NanoStar® R laser, achieve particularly good results because they efficiently break down fine pigment particles. Numerous studies confirm the effectiveness of this treatment method and high patient satisfaction.
Patients interested in a consultation or treatment with the NanoStar® R laser can schedule an appointment at ROC Derma in Aschheim at any time. During the consultation, we will discuss your skin type, the nature of the pigmentation issue or tattoo, and your individual expectations in detail. Together, we will create a customized treatment plan that includes the number of sessions, the intervals between appointments, and aftercare.
