Hundreds of thousands of baby boomer women who think they've found an antidote to aging in cosmetic facial fillers must be better informed of possible risks, government health advisers said Tuesday.
A panel of independent advisers urged the Food and Drug Administration to revise the labeling to include the possibility of long lasting reactions such as bumps under the skin, blotches and scars.
"It is almost a no-brainer," said Dr. Michael Bigby, a Harvard Medical School dermatologist. "The current label is not adequate." The gel-like fillers, which have become hugely popular in the last few years, are injected into the face to smooth away wrinkles.
Manufacturers and plastic surgeons say fillers have an excellent safety record. But Tuesday's FDA hearing raised questions about unapproved uses, untrained technicians giving injections, and a lack of long-term safety data. The hearing was a first step as the FDA considers whether to regulate fillers more closely.
Plastic surgeons pledged to help the government track safety, improve training and provide clearer information to consumers.
Women, and even some men, are drawn to skin fillers by the promise of youthful good looks at far less cost and trouble than a face lift. A touchup two or three times a year can boost deflated middle-age egos. Unfortunately, for some patients, the result can be blotchy skin, bumps on the face and worse.
Different from Botox, which is derived from a toxin that acts on facial muscles, wrinkle fillers are like the biological equivalent of a bit of spackle, except they're injected into the face. They include such products as Juvederm, made by Allergan, Inc., and Restylane, from Medicis Aesthetics Holdings.
FDA officials are concerned that fillers are being used for purposes they were never tested and approved for, such as plumping the lips, which are extremely sensitive.
There are also questions about a lack of clinical evidence on how darker-skinned patients fare with the beauty treatments. More black, Latino and Asian patients are trying plastic surgery, and some information suggests they may be susceptible to unsightly blotches and other complications from fillers.
"The trouble is that once this material is in the hands of physicians, there's really not much control over how it's used and where it's placed," said Dr. Scott Spear, a Washington plastic surgeon. "That creates the potential for a certain amount of mischief.
"But the good news is that, by and large, these are very safe materials," Spear added. "They have a very healthy risk profile."
FDA scientists will present the advisory panel with data on 823 patients who suffered serious reactions after treatment with fillers between 2003 and this September. The overwhelming majority were women, and the most common age group was 50- to 60-year-olds. Plastic surgeons performed some 1.5 million cosmetic surgery procedures with fillers last year alone.
Although no deaths were reported to the FDA, the complications were troublesome enough that 638 of the patients required follow-up medical treatment.
Most reactions involved minor swelling and redness, complications that could be expected. But the FDA said it also received reports of "serious and unexpected" problems, including facial, lip and eye paralysis, disfigurement, vision complications and some severe allergic reactions.
A small number of patients -- 19 -- went to the emergency room with life-threatening allergic reactions, such as difficulty breathing. Twelve developed infections that required hospitalization.
"The FDA has been rushing these products to market as if they were lifesaving medical products," said consumer activist Diana Zuckerman, president of the National Research Center for Women & Families. "They should be requiring better studies since these products have only cosmetic benefits but potentially lethal risks."
Some problems reported to the FDA may be due to unapproved or "off-label" use of fillers. For example, the FDA does not recommend them for plumping the lips, but some doctors see no problem with that.
Another challenge is the sheer variety of fillers. Most are eventually absorbed into the body, but one type contains tiny, round, smooth plastic particles that the body does not absorb. Some are made from natural substances and others are not. That means they may react differently in the body.
