Effects of Application LED Therapy and Laser Therapy in Facial Rejuvenation: Pilot Study

This is a pilot study seen the lack of studies on the subject chosen for a sample calculation accurately be defined. This will be done by 32 volunteers, respecting the criteria for inclusion and exclusion previously cited by reading and signing the Informed Consent and Clarified. The sample comprises a total of 30 subjects, divided randomly into two groups with 16 subjects in each. The first group will make use of both techniques in combined study: Infrared Laser and Led Amber. The second group, in turn, will use only the Led Amber.These will be allocated randomly and intervention will be simple blind.They will be held 10 sessions in individual applications, both group 1 (Laser and LED) and group 2 (LED) and applications for two groups will occur once per week. Group 1 will make the application of the two techniques on the same day session. Both will be applied in the following areas of the face: chin / perioral, nasolabial folds, periorbital, frontal and glabellar region. Both groups act as their own controls before starting the sessions, to ensure that the changes observed in the skin is caused by the treatment of fact and not the environment. For this, the volunteers will be accompanied during the first month, with completion of a photograph at the beginning of the month to another month-end, as well as a questionnaire at the end of 30 days.

To monitor the results, will be held 4 shoots of the subjects in the study. The first session will take place at the first meeting with the patients, who will undergo a 4-week follow-up without using any methodology. After these four weeks, a new shoot will be held to determine whether the environment was able to promote changes in the skin of patients or not. After this, it will start to bare-sessions. After five sessions of treatment, a new picture for monitoring will be held, and repeated this procedure at the end of treatment for so yes, compare the images and get search results.

To carry out the photos, there will be a standard procedure in order to maintain quality, the angle and the light always the same, so that the results observed can be truthful fact. Initially, the face of the patient will be cleaned, particularly aiming at the removal of cosmetic and excess oil on the surface to be photographed. This will precede the photographic record in at least 5 minutes so that friction marks and flushing fall apart.

Afterwards, the patients with the prisoners hair (or using burrows), will be photographed standing in front and lateral planes (both sides), parallel to the plane of the camera sensor. To better guide them, will be applied on the floor marks with the positions of the feet, to be followed.A camera mounted on the tripod, level and horizontal position, with the 105mm lens will be placed in proper height for framing the mouth, forehead and brows. The framework of each area will follow the alignment of facial landmarks to the camera's viewfinder grid in live view mode.

To photograph the brow area both iris will be aligned with the intersections between the line dividing the room and the lower horizontal lines that divide the extreme vertical side rooms of the grid. To shoot the mouth area "Cheilion" the two points will be aligned respectively with the intersections between the line that bisects the grid and the lines that divide the extreme horizontal side rooms. To photograph the area of the forehead (both sides) and the "Exocanthion" and "Otobasion Superious" points will be aligned with the intersections between the line that bisects the grid and the lines that divide the extreme horizontal side rooms. The flash is mounted on the hot shoe of the camera, set in TTL mode with the driven diffuser and will have its head directed forward. The camera will be displayed in manual mode, with f5.6 aperture, shutter speed to 1/60 second and 200 ISO.
