INTRODUCTION : The use of light in the treatment of various dermatological conditions is known to human beings since ancient times. Light was used by Hindu and Greek physicians along with plant extracts in the treatment of Vitiligo. Neils Finsen was awarded the 1903 Nobel Prize in Medicine for establishing the scientific basis of using light to treat skin disease. Since then light therapy has advanced in leaps and bounds with the advent of lasers, photodynamic therapy and phototherapy. Lasers were first conceived in 1917 through the vision of Albert Einstein, when he hit upon the possibility of stimulated emission of radiation. The world had to wait another ten years for the first laser –the RUBY laser to be built by T.Maiman. Lasers expanded into medicine in the early 1960s with focus on the skin and eye, as they were easily accessible. Lasers have now revolutionized the practice of dermatology, promising innovative treatment for a host of skin conditions including vascular and pigmented birthmarks, tattoos, scars, rhytids and unwanted hair. Intense Pulsed Light (IPL) technology burst into the scene in the mid 1970s. They were first introduced for the treatment of vascular disorders, but are now popular among both cosmetologists and physicians for the treatment of unwanted hair, pigmented blemishes and more. Unlike lasers, they use broad band non coherent light: Like lasers, they work on the principle of selective photothermolysis of target chromophores. In spite of their extreme popularity, they do have limitations, which has to be kept in mind .They are not a panacea for all cosmetological skin conditions. Most studies based on IPL published in the literature stem from the western world and use patients with Caucasian skin types. There are a few reports on Asian skin from the Far East. Unfortunately, there are almost no published studies of IPL done on Indian skin types. Even as the popularity of IPL increases, lack of such vital data is of concern to all. This study aims to be a preliminary study gauging the effect of these light systems on Indian skin. It aims to ascertain the efficacy, the tolerability and the adverse effects of IPL when used for patients of Indian skin types. We hope to obtain preliminary data, comparing the study results with western data. IPL is becoming extremely popular and widely used in India these days. Hence the knowledge of this data is essential to Indian Dermatologists. AIMS OF THE STUDY : 1. To study the effect of broad band intense pulse light source for various dermatological indications. 2. To study the efficacy of the intense pulsed light in patients with dark skin types (Fitzpatrick 3 – 5) 3. To study the incidence of side effects in dark skinned patients following the IPL treatment procedure. CONCLUSIONS : 1. IPL is an effective and versatile tool in the treatment of different dermatological problems. 2. Efficacy was noted to be highest in the treatment of unwanted hair followed by acne vulgaris and pigmentary disorders in that order. 3. Average number of sessions required for excellent response in hair removal was 2.9. 4. In the treatment of acne vulgaris inflammatory lesions responded the best. Poor response was seen in the removal of comedones. An average of 3.4 treatment sessions was used. 5. An average of 3.3 treatment sessions was used in treatment of pigmentary disorders. Good results were seen in lentigenes, freckles, post acne hyper pigmentation and melasma. 6. Results close to that obtained in Caucasian skin can be obtained in Asians through proper patient selection and strict adherence to pre treatment and post treatment therapeutic protocol. 7. Adverse effects with IPL were minimal and transient. Hence IPL appears to be safe for use on Indian skin.
