Fractional laser skin rejuvenation has recently gained a lot of interest due to the fact that the remaining healthy tissue around the fractional damage spots can act as healing centers. The approach, to date, has been forming the fractional pattern as a two-dimensional matrix; resulting in the illuminated columns below the spots being damaged uniformly (see Fig.1 b). For ablative and skin-surface treatments this approach is very effective as it allows a ‘lighter' variant of the traditional ablative procedure to be completed, with a lower density effect and faster recovery times. However, for non-ablative, deeper, skin-volume treatments this technique is non-selective with regard to local skin imperfections, and is therefore less suited for these particular procedures.
For this reason Fotona is also pioneering the novel FRAC3 laser treatment, based on their Nd:YAG Accelera pulse mode characteristics. The method produces a three-dimensional, fractional pattern within the epidermis and dermis, with damage islands located predominantly at the sites of minute skin imperfections and/or inhomogeneities (See Fig.1c). This self-induced fractionality has been found to be especially pronounced in skin with a higher number of aging imperfections.
