“…3,4). The low rate of C6 related side effects (Table 3) in this study is comparable to other reports showing a rate of hyperpigmentation from 2.2% to 44% [5,6] and hypopigmentation from 0% to 7.6% [7,8]. Notably, there were no cases of textural changes and/or scars while others reported this complication in up to 25% [9].…”

Background and Objectives: Multiple treatments of resistant tattoos often result in fibrosis and visible textural changes that lessen response to subsequent treatments. The aim of this study is to evaluate the influence of beam profile and spot size on clearance rates and side effects in the setting of resistant tattoos. Study Design/Material and Methods: Thirty-six professional, black tattoos (32 patients) were treated unsuccessfully with a Q-switched Nd:YAG laser (MedLite TM C3, HoyaConBio Inc., Fremont, CA). Because of therapy resistance all tattoos were re-treated using a new generation Nd:YAG laser (MedLite TM C6, HoyaConBio Inc.). Maximum energy fluence (E max ), mean energy fluence, mean spot size, level of clearance, side effects and beam profile (irradiance distribution) of both laser systems were assessed and evaluated in a retrospective study. Results: All tattoos were previously treated with the C3 laser at 1,064 nm using a mean E max of 5.8 AE 0.8 J/cm 2 (range 3.8-7.5 J/cm 2 ) as compared with a mean E max of 6.4 AE 1.6 J/cm 2 (range 3.2-9.0 J/cm 2 ) during the C6 treatment course. Corresponding spot sizes were larger during C6 treatments as compared with C3 (5.0 AE 0.9 and 3.6 AE 0.2 mm, respectively). The C6 laser had a ''flat top'' and homogenous profile regardless of the spot size. For the C3 laser the beam shape was ''Gaussian,'' and the homogeneity was reduced by numerous micro-spikes and micro-nadirs. After the C6 treatment course 33.3% of the tattoos showed clearance of grade 1 (0-25%), 16.7% of grade 2 (26-50%), 16.7% of grade 3 (51-75%), 30.5% of grade 4 (76-95%), 2.8% of grade 5 (96-100%). The total rate of side effects due to C6 treatment was 8.3% in all tattoos (hyperpigmentation 5.6%, hypopigmentation 2.7%, textural changes/scars 0%). Conclusion: This clinical study documents for the first time the impact of a 1,064-nm Nd:YAG laser with a more homogenous beam profile and a larger spot size on the management of resistant tattoos. Only a few treatment sessions were necessary to achieve an additional clearance with a low rate of side effects.

“…Q-switched ruby and Nd:YAG lasers have been studied and used safely in the treatment of patients of Ethiopian origin with tribal/religious tattoos. 55,56 In a study involving 404 Ethiopian Jews with SPT V and VI, blue/black charcoal-based tattoos (mostly involving the head and neck) were treated with the Q-switched Nd:YAG (n = 380) or ruby (n = 24) laser. Self-limited mild hyperpigmentation lasting 2-4 months was noted in 177 (44%) patients.…”

“…Self-limited mild hyperpigmentation lasting 2-4 months was noted in 177 (44%) patients. 55 Given the higher risk of pigmentary complications in SPT V and VI (especially when treating complex or multicoloured tattoos), test treatments are recommended. The use of the lowest effective fluence is also a preferred approach to minimize laserinduced dyschromias.…”

SummaryEthnic skin or 'skin of colour', which is characterized by increased epidermal melanin, labile melanocytes and reactive fibroblast responses, poses special challenges for the use of laser and light-based therapies. These therapies are associated with a greater risk of dyspigmentation and scarring in ethnic skin and therefore require careful selection of device and treatment parameters to minimize complications. Whereas early-generation lasers for hair removal and resurfacing were generally contraindicated for individuals with Fitzpatrick skin phototypes (SPT) IV-VI, advances in the past decade have given rise to a range of devices that can be safely used in ethnic skin. Longer wavelength lasers such as the 810 and 1064 nm Nd:YAG; intense pulsed light and monochromatic excimer light (308 nm); fractional lasers; and radiofrequency devices have all been used safely for hair removal, pigmentary abnormalities, resurfacing and skin tightening in ethnic skin, respectively. Notwithstanding these advances, nuances in the laser or light treatment of darker skin types remain and must be considered to ensure safe therapeutic outcomes. The vast majority of published data pertaining to lasers and light treatments in nonwhite skin involve patients of East Asian ethnicity (e.g. Korean, Japanese, Chinese, Thai). By contrast, there is a paucity of studies involving individuals of African ancestry or those with SPT V or VI. This article will review laser and light-based modalities that are considered safe and effective for individuals with richly pigmented skin. What's already known about this topic?• Published data or recommendations on the safe and effective use of lasers in Fitzpatrick skin phototypes (SPT) V and VI are limited. What does this study add?• This review addresses knowledge and practice gaps by summarizing available data on the use of lasers in patients with SPT V and VI, a subset of the population in which the risk of iatrogenic pigmentary and scarring complications is highest.• This provides clinicians with practical knowledge of which devices have been studied in SPT V and VI and offers treatment recommendations to improve outcomes.Traditionally, the literature on cosmetic procedures, especially laser and light-based therapies, has focused on the treatment of individuals of European ancestry with Fitzpatrick skin phototypes (SPT) I-III. Safety limitations of first-generation technologies as well as socioeconomic, demographic and cultural factors may contribute to the relative lack of studies involving the various racial/ethnic groups with constitutively darker skin. Shifts in the aforementioned contributing factors have led to considerable increases in the performance of cosmetic procedures in nonwhite racial/ethnic groups. According

ÖzetDünyadaki birçok farklı kültürde yüzyıllardır tatuaj yapılagelmektedir ve tatuajların giderilme çabaları tatuaj tarihi kadar eskidir. Geçmişte sıklıkla uygulanan destrüktif yöntemler taşıdıkları yan etki riski ve tedavi yetersizlikleri nedeniyle modern tatuaj tedavisinde önerilmemektedir. Minimal yan etkiyle tatuajların etkin bir şekilde tedavisine olanak sağlayan Q-anahtarlı lazerler son yıllarda yaygınlaşmıştır. Bu amaçla en sık kullanılan Q-anahtarlı lazerler; Q-anahtarlı ruby, Q-anahtarlı Nd-YAG ve Q-anahtarlı alexandrite lazerlerdir. Her bir Q-anahtarlı lazerlerin avantajları yanında yetersizlikleri ve yan etkileri de mevcuttur. Hekim, tatuajın yapısı ve etiyolojisi ile hastanın cilt tipine göre doğru tedavi yaklaşımını belirlemelidir. Doğru cihaz seçimi ve uygun tedavi parametrelerine rağmen, dispigmentasyon, pigment koyulaşması ve allerjik reaksiyonlar gibi bir çok yan etki karşımıza çıkabilir. Daha spesifik lazer sistemlerine yönelik gelişmeler tatuajların daha hızlı ve daha etkin bir şekilde giderilmesini sağlayacaktır. Sum maryTattoo is being practised for centuries in many cultures throughout the world and attempts to remove tattoos is as long as the history of tattoos. The destructive modalities, frequently used in the past, are not recommended for modern tattoo removal because of the risk of side effects and treatment failures. Q-switched lasers, allowing efficacious removal of tattoos with minimal side effects, have become widespread over recent years. The most common Q-switched lasers being used for this purpose are the Q-switched ruby, Q-switched Nd-YAG and Q-switched alexandrite lasers. Each Q-switched laser has some side effects and inabilities beside its own advantages. The physician has to determine the correct treatment modality according to the structure and etiology of the tattoo and patient's skin type. In spite of the correct device and appropriate treatment parameters, many side effects, such as dyspigmentation, pigment darkening and allergic reactions, can be encountered. Technological developments leading to more specific laser systems will let the tattoos to be more quickly and better removed. Gi riflTatuaj uygulamalarının tarihçesi bronz çağ kadar eskiye dayanmaktadır 1 . Deriye farklı yapı ve renklerdeki pigmentlerin enjeksiyonu ile çeşitli şekil ve işaretlerin kalıcı hale getirilmesi işlemi olarak tanımlayabileceğimiz tatuajlar, kişilerin dini inançları, fikirleri, duyguları ve aidiyetleri gibi pek çok özelliklerini içinde bulundukları topluma ve kendilerine ifade etme şekli olarak kabul edilebilir. Başlangıçtaki amaçları her ne olursa olsun, zamanla kişiler kalıcı olması niyetiyle yaptıkları bu şekillerin vücutlarından çıkarılmasını isteyebilmektedirler ve bu talep, toplumdaki tatuaj yaygınlığı ile doğal olarak ilişkilidir. Tatuajda yerleştirilen pigmentlerin büyük bir bölümü özellikle kan damarları çevresinde yerleşen dermal fibroblastlar ile makrofajlarda bulunur ve fibrotik bir yapı ile çevrelenir.
