RESUMO
Following our survey, we can appreciate that a variety of laser platforms exist to rejuvenate the skin by resurfacing the outer layer of the skin as well as heating the lower layers of the dermis. Based on reliable clinical effectiveness and a limited side effect profile, we can confirm that nonablative fractionated technologies greatly improve the appearance of lentigines, rhytids; eliminate sun damage, attenuate scarring due to acne and other causes; and treat hyperpigmentation. The Fraxel (Solta Medical) laser system delivers pulses across a wide range of density and energy levels. We determined that when increasing the pulse energy this led to an increase in thermolysis microzone depth and width without damaging the surrounding tissue. Due to its performance and various clinical applications, Fraxel laser can be optimally considered to be the gold standard for skin rejuvenation.
