There has been considerable interest in using non-ablative methods to rejuvenate the skin. The ThermaCool TC (Thermage Inc.) is a radiofrequency (RF) device that has been introduced to induce tightening of the address the problem of skin via a uniform volumetric heating into the deep dermis tightening, resulting in a 'non-surgical facelift'. Radiofrequency produces a uniform volumetric heating into the deep dermis. Twenty treatment areas in 17 patients were treated to evaluate the efficacy and safety of RF treatment to the brow and jowls. The technique was found to produce gradual tightening in most patients, and there were no adverse effects

Fat transfer is most effective when fresh fat is used, with excess fat frozen and saved for touch-ups. The obvious benefit to using frozen fat is that harvesting does not have to be done each time fat is injected. It is important to be able to easily store the fat in a freezer and be confident that it will not harbor bacterial growth. We studied frozen fat from 10 patients after 12 months and 10 patients after 24 months for sterility. Cultures were negative for all specimens, showing that frozen fat is safe to use and should not cause infection

BACKGROUND: Bovine collagen is extensively used for facial soft tissue augmentation but provides only temporary correction and can cause hypersensitivity reactions. Hyaluronic acid derivatives potentially offer improved longevity of correction and a reduced risk of immunogenicity and hypersensitivity. OBJECTIVE: To compare the efficacy and safety of nonanimal stabilized hyaluronic acid gel (Restylane; Q-Med, Uppsala, Sweden) with that of bovine collagen (Zyplast) for treatment of nasolabial folds. METHODS: One hundred thirty-eight patients with prominent nasolabial folds were randomized to treatment with hyaluronic acid gel and bovine collagen on contralateral sides of the face. Treatments were repeated at 2-week intervals, as required, to achieve "optimal cosmetic result" (baseline). Outcomes were evaluated by a blinded investigator at 2, 4, and 6 months after baseline. RESULTS: Less injection volume was required for "optimal cosmetic result" with hyaluronic acid gel than with bovine collagen, and patients and investigators judged hyaluronic acid gel to be more effective in maintaining cosmetic correction. The investigator-based Wrinkle Severity Rating Scale and Global Aesthetic Improvement Scale assessments at 6 months after baseline indicated that hyaluronic acid gel was superior in 56.9% and 62.0% of patients, respectively, whereas bovine collagen was superior in 9.5% and 8.0% of patients, respectively. The frequency, intensity, and duration of local injection-site reactions were similar for the two products. CONCLUSION: Nonanimal stabilized hyaluronic acid provides a more durable aesthetic improvement than bovine collagen and is well tolerated.

This is a basic overview of liposuction. Liposuction is the removal of fat using cannulas (tubes) inserted through tiny incisions into the adipose tissue. When done correctly, nice results can be safely achieved with a very easy procedure

Tumescent liposuction is a safe and effective procedure. It is best used in normal individuals with localized areas of adiposity and good overlying skin tone. Patients must have realistic goals and expectations. Meticulous surgical technique is essential, and care must be taken to remove the correct amount of fat in the appropriate plane. Careful patient selection following a preoperative assessment will result in a very satisfying procedure for both the patient and physician
