Fractional scanner to treat the cheeks, chin and nose areas with 2cm diameter round field, 1.2mm spot size, 60Hz, random mode and 70% coverage.

Case Study 2 A 57 year old female presented with moderately severe photodamage from chronic sun-exposure. She had broken capillaries, solar lentigines and multiple actinic dysplasias and keratoses. She underwent a single session combination treatment with the 532nm laser and IPL, in conjunction with amino levulinic acid (ALA) photodynamic therapy. The skin was pre-treated with 20% topical ALA 60 minutes prior to the laser treatment. Topical lignocaine/tetracaine anaesthesia was also applied for increased patient comfort. The discrete capillaries were treated with the 532vascular laser on standard handpiece mode (1.2mm spot size, 10j/cm², 15ms, 5-10Hz, contact cooling, standard mode). This was followed with IPL field treatment to further activate the ALA photo sensitizer. There was a significant improvement in the photo damage and overall appearance and texture of the skin with noticeable reduction in the telangiectases, lentigines and dysplastic lesions.
