Comparison of SHR Mode IPL System with Alexandrite and Nd: YAG Lasers For Leg Hair Reduction

Abstract

Objective: Multiple lasers and light sources are currently available for hair removal and many studies comparing efficacy and safety exist. SHR mode IPL is a technique that gives the total energy in divided doses with fewer side effects. We compared a SHR mode IPL system with alexandrite and Nd: YAG lasers for leg hair reduction Material and Methods: Twenty-five female participants with skin types II–IV, underwent treatment of unwanted hair on the cruris. Three selected areas were randomly treated with the SHR mode IPL system, Alexandrite laser and Nd: YAG laser in three sessions. Hair reduction was evaluated with digital photography by a blinded assessor every 6 weeks and 6 months after the last session. Pain severity, side effects and patient satisfaction analysis were also investigated. Results: Twenty-one participants completed the trial. The mean hair reductions in 6 weeks after the last treatment were 50% for the IPL system, 53% for Alexandrite and 39% for the Nd: YAG lasers. However after 6 months; 40%, 49% and 34% hair reduction was observed, respectively. The Alexandrite laser was the least painful system. Conclusion: Although there is no obvious advantage of one laser system over the others in terms of treatment outcome, the Alexandrite laser is still the most efficient and reliable way of hair removal in fair skinned individuals. Turkish Başlık: Bacak Kıllarının Azaltılmasında SHR Mod IPL Sisteminin Alexandrite ve Nd:YAG Lazer ile Karşılaştırılması Amaçlar: günümüzde epilasyon amaçlı kullanılan çok sayıda lazer ve ışık kaynağı mevcut olup; etkinliği ve güvenliği karşılaştıran birçok çalışma bulunmaktadır. SHR mode IPL toplam enerjiyi bölünmüş dozlarda vererek daha az yan etkiye neden olan bir tekniktir. Bacak kıllarının azaltılmasında shr mod ıpl sistemini alexandrıte ve nd:yag lazer ile karşılaştırdık. Hastalar ve Metod: cilt tipi ıı-ıv olan 25 bayan hasta istenmeyen bacak kılları nedeniyle tedaviye alındı. Seçilmiş 3 bölge randomize olarak shr mod ıpl, alexandrıte ve nd:yag lazer ile 3 seans tedavi edildi. Son seanstan sonra kıllardaki azalma 6. Hafta ve 6. Ayda kör bir değerlendirici tarafından dijital foğraflama ile değerlendirildi. Ağrı şiddeti, yan etkiler ve hasta memnuniyeti sorgulandı. Sonuçlar: Çalışmayı 21 katılımcı tamamladı. Son tedaviden 6 hafta sonraki değerlendirmede kıllardaki ortalama azalma ıpl sistemi için %50, alexandrıte için %53 ve nd:yag lazer için %39ʼdu. Diğer yandan 6 ay sonra kıllardaki azalma sırasıyla % 40, % 49 ve % 34 idi. Alexandrıte lazer en az ağrılı sistemdi. Karar: tedavi sonuçları açısından birinin diğerine olan üstünlüğü açıkça gösterilememiş olsa da alexandrıte lazer açık tenli kişilerde epilasyon amaçlı kullanılan lazerler içinde halen daha etkili ve güvenilir lazer olmaya devam etmektedir.
