Objectives: How can we analyze pigmentation based on objective assessment methods?

Introduction: Changes in skin color provide important clues to disease progression or response to treatment. The assessment and perception of skin color is often subjective.

Conclusion: Skin pigmentation analysing tools must be quantitative and independent of the observer and the skin color. We present our daily practice using different techniques including Wood's light, dermoscopy, reveal imager and colorimetry.

Objectives: The Q switched lasers have become one of the most versatile devices in laser practice in the recent past. The objective of this presentation would be to bring forth the latest techniques employed in the use of the Q switched Nd:YAG lasers and to demonstrate the versatility of these newer systems.

Introduction: The Q switched lasers have become one of the most versatile devices in laser practice in the recent past. The objective of this presentation would be to bring forth the latest techniques employed in the use of the Q switched Nd:YAG lasers and to demonstrate the versatility of these newer systems.

Materials / method: The 532nm wavelength has always been a difficult wavelength to use in darker skin considering its absorption into both the melanin and the oxyhemoglobin. This leads to a greater generation of heat in the epidermis that can lead to more collateral damage in the dark skins with resultant likelihood of post laser complications like hypo and hyper pigmentation and scaring
The availability of the dye kit hand pieces in the newer QSLs has made it possible to produce 660 nm wavelength which is safer than the 532nm due to its specificity of absorption into the melanin sparing the hemoglobin

The avail

Results: The epidermal lesions like freckles and lentigines can be treated easily in the darker skins without the likelihood of post laser complications

We have been using the 660 nm wavelength to treat the epidermal pigmented lesions like freckles and lentigines in our patients with dark skin and have found that it is equally efficacious as the 532 nm wavelength and at the same time is associated with lesser post laser complications

Conclusion: To conclude the newer additions to the QSLs has made these machines extremely versatile and useful in the present day derma laser practice. The availability of the 660 nm wavelength has reduced the possibility of serious post laser complications in skins of colour while maintaining the efficacy of treatment
