Top 10 most popular cosmetic procedures in U.S.

How popular is cosmetic surgery in the U.S.?

That number rose 1 percent from 2010 - and over 197 percent since 1997. Just what procedures are people so keen on having? Keep clicking to see the top 5 surgical and top 5 nonsurgical procedures in 2011...

Surgical - 5. Breast lift

Number of procedures in 2011: 127,054

During a breast lift, a surgeon makes incisions around the breast and areola to remove excess skin and shift the nipple and areola to a higher position. Skin that was formerly located above the areola is brought down and together beneath it to reshape the breast. Risks include bleeding, infection, reactions to anesthesia or asymmetry, says the ASAPS.

Surgical - 4. Cosmetic eyelid surgery aka blepharoplasty

Number of procedures in 2011: 147,540

A blepharoplasty is performed on people with excess skin on the eyelids that may impact vision or on folks with a "puffy appearance" or bags and circles under the eyes. Incisions are made in the upper or lower eyelids to remove excess skin and fatty tissue. Risks include hematoma (an accumulation of blood under the skin), infection, scarring or damage to underlying structures and impaired eyelid function.

Surgical - 3. Tummy tuck aka abdominoplasty

Number of procedures in 2011: 149,410

An abdominoplasty is a procedure that removes excess or sagging abdominal skin. Generally, a horizontal incision is made above the pubic area or above the belly button, depending where the loose skin resides. To tighten the abdominal wall, the surgeon brings loose underlying tissue and muscle together with sutures. Risks include bleeding, infection, tissue loss along the incision or fluid buildup under the skin.

Surgical - 2. Breast augmentation

Number of procedures in 2011: 316,848

During breast augmentation, an incision is made by a surgeon who creates a pocket underneath the pectoral muscle for the implant to be inserted. Women can get either a saline or silicone-filled implant. Risks include scarring, infection and a potential need for the implants to be removed in the future, the society says.

Surgical - 1. Liposuction aka lipoplasty

Number of procedures in 2011: 325,332

Liposuction removes areas of fat deposits around the body via a hollow metal suction tube that is passed through the fatty tissue. Sometimes an ultrasound is used to break down fat cells for removal. Complications are infrequent, but include hematoma, infection, scarring or other indentations or skin irregularities.

Nonsurgical - 5. IPL laser treatment

Number of procedures in 2011: 439,161

Treatment with "intense pulsed light" can remove skin pigmentation problems such as birth marks or age spots. The light is applied to the skin's surface to change the skin's melanin (brown pigment) making them less visible. Skin irritation is a potential risk.

4. Microdermabrasion

Microdermabrasion: 499,427

Microdermabrasion removes crow's feet, age spots and acne scars through a mechanical handpiece that is applied to the skin and removes dead skin cells and stimulates new cell and collagen growth. According to the ASAPS, there are virtually no side effects.

3. Laser hair removal

Number of procedures in 2011: 919,802

Laser hair removal often utilizes a low-energy laser beam that passes through a patient's skin down the hair shafts, disabling hair growth. Patients may experience slight redness of the skin or mild swelling around the hairs and patients with darker skin may not respond as well, the ASPS says.

2. Hyaluronic acid (including hylaform, juvederm, perlane/restylane)

Number of procedures in 2011: 1,206,186

Hyaluronic acid includes a class of soft tissue fillers used to treat wrinkles or facial aging. The compound is injected into the skin - results last for 3 months in "high mobility" areas such as the lips, and up to a year for "smile lines" around the nose. Risks include bruising, lumpiness, redness, and in rare cases local infections.

1. Botulinum toxin type A (including Botox and Dysport)

Number of procedures in 2011: 2,619,739

This class of injections use botulinum, a neurotoxin that blocks nerve signals to temporarily weaken or paralyze the muscle causing a wrinkle. Risks include bruising, infection (more rare), and the possibility of affecting nearby muscle groups.
