Trichloroacetic acid chemical reconstruction of skin scars showed efficacy in ice pick scars. Grade 4 scars improve poorly with resurfacing procedures, where punch excision and punch elevation can be tried. Platelet-rich plasma therapy was effective in combination with lasers and microneedling. Overall there is lack of high-quality data in the management of post acne scars. Combination treatment has shown better efficacy compared to single modalities.The diagnosis of aging based on the morphogeometric changes experienced by the face, measured by the application of facial stratigraphic semiology by thirds, could become a novel approach that guarantees an efficient replacement of aged tissues through minimally invasive aesthetic medicine strategies. Facial aging should be analyzed by thirds, because not all thirds grow old at the same time. Owing to this is necessary go giving solve the aging problems each one of them, by means of therapies of the facial restructuring into sequential treatment appointments, with the purpose of being go giving time to the tissues rearrangement of the face, so that it is perceived as a subtle progressive reversal of aging and so generate a comfortable social acceptance of the resulting changes of said facial rejuvenation. This article intends to present the practical approach of the concepts and guidelines illustrated in the routine aesthetic diagnosis, the anatomical changes in the various tissue layers that are externally appreciated, but detailing them under a regional approach (upper, middle, and lower thirds). Our paradigm seeks that as professionals of aesthetic and regenerative medicine we identify facial aging not only as the obvious wrinkles and other changes in the skin, but that we diagnose acc
