Tattooing has been practiced for at least two thousand years. Much effort has been exerted in attempting to make tattoos brighter, more colourful and stable. In the present, it is believed that laser therapy is the best method in cosmetic terms of tattoo removal. Aims: Evaluate the efficacy and safety of Q switched ND YAG laser in tattoo removal. Materials and Methods: This was a "randomized, prospective, interventional" single centre study carried out in dermatology outpatient department of GMERS Medical College, Gandhinagar, Gujarat, a tertiary care teaching hospital in western India. Total 89 patients with tattoo of red, green, blue and black colour in scripted on different parts of their body according to inclusion and exclusion criteria were enrolled for a period of 1 year and 5 months (January 2016-May 2017) in our study. Results: Majority of the participants (58.5%) were from 21-25 years of age group. Mean age of participants was found out to be 21.9 years. Amature tattoo 63(70.8%) were outnumbered then professional tattoo 26(29.2%). Blue-black tattoo (92.1%) was more common than red-green (7.9%) colour tattoo. Most common reason for tattooing was fashion (69.7%). More than three fourth participants (78.7%) needed ≥ 6 sittings for tattoo removal. In 13.5% participants, it was ≥10 sittings while in others (7.8%) it was 3-5 sittings. Conclusion: Excellent response was seen in amature tattoo group as comparison to professional tattoo group and almost all of the study participants were either satisfied or very satisfied. Only minor adverse reactions were reported after tattoo removal.

ÖzetDerinin pigmente lezyonları, kozmetik ve psikolojik rahatsızlıklar oluşturabilen sık karşılaşılan durumlardır. Pigmente lezyonların tedavisinde lazer kullanımı Q-anahtarlı lazerlerin kullanıma girmesiyle son yirmi yılda artmıştır. Pigment spesifik ve pigment spesifik olmayan lazerler; lentigo, nevüs, melazma, efelid, cafe au lait makülleri, Becker nevus, postinflamatuar hiperpigmentasyon gibi pek çok farklı pigmente lezyonun tedavisinde etkin ve güvenilir olarak kullanılmaktadır. Pigmente lezyonlar epidermal, dermal-epidermal ve dermal yerleşimlerine göre değerlendirilmekte ve lezyon derinliğine göre uygun lazer sistemi ile tedavi edilmektedir. Pigmente lezyonların tedavisinde olası komplikasyonlar ve malinite riski çok iyi değerlendirilmeli ve hasta için en uygun lazer sistemi tercih edilmelidir. Uygun hastalarda doğru lazer sistemi kullanıldığında tedavi etkinliği ve güvenirliği oldukça yüksektir. (Türk derm 2012; 46 Özel Sayı 1: 23-9) Anah tar Ke li me ler: Deri, pigmente lezyon, lazer, tedavi Sum maryPigmented lesions of skin are common situations that can lead to cosmetics and psychological disorders. In last twenty years, usage of lasers in the treatment of pigmented lesions is increased with the introduction of Q-switched lasers. Pigment specific and pigment nonspecific lasers can be used safety and effectively in the treatment of various pigmented lesions including lentigo, nevus, melezma, ephelides, cafe au lait macules, Becker's nevus and postinflammatory hyperpigmentation. Pigmented skin lesions are evaluated by their epidermal, dermal-epidermal and dermal locations and the most appropriate laser system is chosen by its location. The risk of complications and malignancy should be considered very carefuly before the treatment and the most appropriate laser system should be chosen for the patient. Efficacy and safety of the laser treatment is very high in selected patients which were treated by appropiate laser systems. (Turk derm 2012; 46

“…6 Pigment-specific QS lasers like QS ruby, alexandrite, and Nd: YAG lasers have also been used, but their effectiveness is inconsistent. 7 Nanosecond-pulsed QS lasers can target and disrupt individual pigment-containing cells through selective photothermolysis, but they cannot effectively treat groups of nevomelanocytes. 7 Depending solely on QS lasers is insufficient for complete nevus removal.…”

In addition, QS lasers often cause pigment changes post-treatment because of photomechanical damage around the treated area and direct stimulation of melanin in people with darker skin tones.…”

BACKGROUND Acquired melanocytic nevi are common benign skin lesions that require removal under certain circumstances. Shave removal is a straightforward treatment modality with a risk of recurrence. OBJECTIVE To evaluate the outcome of dermoscopy-guided shave removal of acquired melanocytic nevi in the face of dark-skinned individuals who are more liable to postsurgical complications. METHODS The study was conducted on 64 patients with acquired facial melanocytic nevi. Serial shave removal using a razor blade guided by dermoscopic examination was done until nevus-free tissue was seen, followed by electrocauterization of the base. Cosmetic outcome, patients' satisfaction, and recurrence rate were evaluated during follow-up. RESULTS Excellent cosmetic outcome was achieved in 54.69% of patients, while 39.06% had an acceptable outcome, and 6.25% of patients had poor cosmetic outcome. Meanwhile, the recurrence rate was noticed in 5 cases only (7.8%). CONCLUSION Dermoscopic-guided shave removal provides an easy procedure of treating common melanocytic nevi with an acceptable cosmetic result and a lower rate of recurrence even in patients with darker skin phenotypes.
