Fractionalised laser skin resurfacing (FLSR) has become an important component of facial rejuvenation surgery as patients continue the trend of seeking less invasive procedures with low downtime and low risks. This behavioural change in attitude has also been prompted by a realisation of both doctors and patients that the recent much hyped non-ablative methods are not comparable with ablative skin resurfacing and were often subject to extravagant claims in terms of efficacy. * During the nineties, CO2 laser resurfacing was considered the ‘gold standard’ for the treatment of acne scarring, deep rhytids and photo-damaged facial skin. It was one of the earliest gas lasers to be developed (invented by Kumar Patel of Bell Labs in 1964).
