Resumen

Objectives: Understand MLA and LIOB/LIC effects in skin of color when combined with mnrf and tca cross to treat acne scars. Use of nanosecond laser to achieve picosecond laser end points and exploring it as a new and effective avenue as a less downtime combination treatment in skin of color Introduction: As acne scar is a result of deep inflammation Multiple treatment modalities for surgical to nonsurgical, peels to lasers and energy-based devices, and ablative to nonablative fractional and nonfractional are available in our armamentarium to improve acne scars Of all the various modalities available, nanosecond lasers are available for the longest period and now with the latest advances are able to improve most acne scars. Combination of technologies when used sequentially or rotationally improves outcome, thus minimizes side effects. The results are better lasting. Materials / method: We have achieved picolaser end points with nanosecond lasers to improve acne scars and skin texture as a monotherapy and conjunct therapy with mnrf and tca cross. With the advantage of short pulse durations and gaussian beam profile we have treated patients of darker skin type on the highest of energy with varying passes till the end points achieved keeping the scar type and skin type of patient in mind. Results: Results were appreciable in skin texture improvement as a monotherapy alone and were great in acne scars when combined with mnrf and tca cross and the beauty was having lesser downtime.We have been able to achieve appreciable results in improving texture of the skin even in patients with rosacea also. Conclusion: Nanosecond mla toning induced LIOB/LIC can give picosecond laser end points without any adverse events in skin of color with the gaussian beam profile 10mm spot size even on the highest of the energy if the laser Power supply is constant,with the pulse duration of 2-3ns.,which further gives improvement in skin texture and acne scars as a monotherapy and combination therapy with mnrf and tca cross as and when required with the Lowest downtime and offers a new avenue with the same device with the cost affordability specially in countries like india.
