    Estudo do microrelevo cutâneo após o uso da dermaplanagem por meio da fotogrametria digital tridimensional
    (Universidade Brasil, 2021) Ventura, Danielle Bastos da Silva; Frade-Barros, Amanda Farage
    The skin surface is a barrier and can selectively communicate with the internal biological environment and the external environment, it is not flat and contains several straight grooves that can be classified according to depth, and therefore, these conditions that define its micro relief are related to its exchanges and its breathing, so the photogrammetric analysis instruments allow its amplification, making it possible and necessary to describe them. Dermaplaning is a technique used in qualified aesthetic protocols, facial rejuvenation and the treatment of atrophic scars, based on the concept of physically removing the superficial layers of the skin by dragging a blade of sterile, disposable butter from a scalpel. The three-dimensional photogrammetry analysis instruments are modern resources of current tissue bioengineering and allow a form of tissue enlargement in a precise and non-invasive way. Two dermaplaning intervals with 21-day intervals were performed in women between 18 and 38 years old, divided into 2 groups (control n = 21, test n = 21) with complaints of skin texture alteration. The effectiveness of the treatment was evaluated using three-dimensional digital photogrammetry and photothermographic imaging before and after the preparations. The group showed decreased oiliness, local hydration and increased count of elastic and collagen fibers, as well as surface pigmentation, through arbitrary measures provided by the equipment. This study was of fundamental importance to verify, in addition to the changes in the biotype, that there were topographic changes in the cutaneous microrelief after the use of dermaplaning and showed that the technique is a possible effective dermatological or aesthetic therapy to improve the microrelief, but it is necessary its post-procedure skin management.
