Sclerotherapy: A glycerin or saline solution injected into spider veins causes them to collapse; they're then reabsorbed into the body. Three to six treatments may be needed, depending on the size of the area. Cost: $300 and up per treatment.

Sculptra: A poly-L-lactic acid injectable that is considered a "dermal stimulator" because it triggers skin cells to make more of their own collagen. Requires three to four injections over several weeks; lasts about two years. Cost: $850 per injection.

Silicone: A permanent filler used mostly for wrinkles, acne scars, and lip enhancement. Banned in the early '90s for safety reasons, but now FDA approved for ophthalmological uses. Lasts forever. Cost: $500 to $1,000 per injection.

Thermage: Radiofrequency energy heats the lower layers of the skin, causing tightening of collagen. Usually only one treatment is required. Cost: $1,200 to $2,500 (depending on areas being treated).

Thread lift: Barbed sutures are threaded into the tissue of the cheeks, jowls, brow, or neck and then pulled to lift the skin. Cost: $2,500 to $4,000.

Titan: An infrared laser that tightens collagen. Considered less painful than Thermage but requires three to five treatments. Cost: $700 to $2,000 per treatment.
