Brunelli 4 Techniques As applies to the rest of the body, the aging hand is affected by both genetic and environmental factors (photoexposure, climatic and toxic external agents). In the last years, cutaneous rejuvenation techniques have found many solutions to correct simultaneously the several factors responsible for aging. For hand aging in particular, many photorejuvenation techniques have been proposed, such as pulsed light, radiofrequency, cutaneous biostimula- tion, injection of autologous and heterologous materials for remodeling and filling, and chemical peels. Since the aging- related hand defects are variable in number and of varying nature, the techniques are numerous and each one has spe- cific limitations and indications. Photoaging using laser (photorejuvenation) or pulsed light at high intensity aims to eliminate from the face skin (or hands, neck, and décolleté) the signs of phototoxic and aging factors such as age spots, solar lentigines, rosacea, enlarged pores, and fine superficial wrinkles. Photorejuvenation exploits a laser energy beam or pulsed light at high intensity, shooting selectively all the cutaneous benign pigmentations, thus eliminating them progressively and stimulating new collagen formation. The skin to be treated must be as fair as possible, since the light ray targets the melanin and the dark component of the lesion (rosacea, cutaneous freckles, hyperpigmentations, hyperkeratosis). The operator, after a correct evaluation of indication and an accurate anamnesis, must apply on the zone to be treated a transparent gel that carries the light beam to the lesion, thus F i g. Visible is the cutaneous irritation and erythema of the hyperpigmented lesions avoiding thermal damage. The pulses are established on the basis of the areas to be treated and the type of aesthetic defect to be eliminated. This technique allows one to selectively treat the defect without damaging the surrounding tissue, according to the selective photothermolysis principles. The laser applications must be repeated at intervals of 1 month until the defect disappears (generally after 3–6 ses- sions). With photorejuvenation the freckles and the superficial cosmetic defects of the skin are progressively removed, definitively and with very satisfactory results. Major complications consist of superficial burns and persistent edema, which are often transitory and sporadic phenomena (Figs. This procedure treats the superficial pigmented lesions of the skin, and is therefore the ideal treatment in association with deep rejuvenation of collagen using bipolar radiofre- quency. The electric field produced by a radiofrequency tool crosses the tissue, thus determining molecular electric charge modifications according to the Ohm’s law, which states that F i g. Although some authors state that this concept began two centuries ago, it was only in 1950 that the first article on the use of autologous fat (harvested from the patient) for body contouring [5] was published. Since then this technique, soon named lipofilling, has been widely per- formed, albeit with several limitations (above all that there are no long-lasting results) and some contraindications [6]. The idea of enlarging body areas using the fat that is natu- rally in excess was so attractive that many surgeons tried to improve this technique to optimize results in terms of patients’ satisfaction and duration of correction [7, 8 ]. In 1998, Sidney Coleman reported the results obtained with a special technique of preparation and infiltration of Fig. The radiofrequency effect is visible lipostructure may be understood only if the aspects concern- above all at the level of dermal collagen and the deeper ing the original operation and the limitations that the new structures, its main purpose being to improve the tissue laxity technique proposes to go beyond are clear.
