Aging Prevention by Cosmetic Procedures
Posted on: September 8, 2009

In aesthetic dermatology, filling and laser treatments are two essential techniques. Several recent studies on calcium hydroxyapatite in filling treatments and facial volumetry, in esthetics, but also in HIV patients, have been published. It was also tested in accentuated melomental folds where it is superior to hyaluronic acid.

In aging of the skin of the dorsal aspect of the hands, hyaluronic acid provides slightly better results than collagen. Filler rhinoplasty can correct minor deformations of the nose. Lipofilling is advantageous for linear scleroderma of the face, at least in the forehead region, and adipocyte stem cells may be a future solution for facial aging or lipoatrophy.

The risk of local and/or general sarcoid reactions related to interferon in patients having undergone filling injections has been reported.

In the field of laser treatment, fractionated photothermolysis has motivated much more research and seem particularly valuable in treating acne scars, aging of the dorsal aspect of the hands, and, more anecdotally, in colloid milium and pearly penile papules. Laser is also useful in preventing surgical scars where a mini-diode can also be used. For axillary hyperhidrosis, subdermic Nd-YAG laser competes with botulinum toxin, with longer-lasting results.

Solutions are appearing for treatment of red or white striae cutis distensae. Intense pulsed light is the reference technique for poikiloderma of Civatte, and seems effective, with new devices, for melasma. However, inappropriately used by nonphysicians, IPL can cause serious ocular accidents; one case of uveitis has been reported.
