Crows Feet Medical Options

Crows Feet are wrinkles that extend from the outer corner of the eyes. They are part of aging. As the skin ages, it becomes drier, thinner, and less elastic. Crows feet and other types of wrinkles are the result of these changes. Genetics, age, exposure the UV light, and smoking are all factors that contribute to wrinkles. A doctor might treat crows feet by injecting a filler or by injecting Botox. A filler is a substance that smooths out wrinkles by increasing the volume under the skin. Botox is a paralyzing toxin that comes from a bacterium. Lasers, chemical peels, dermabrasion, microdermabrasions, and face lifts are other ways to combat crows feet.

 Filler Injections
Soft tissue fillers are one way to address crows feet. A soft tissue filler is a substance that plumps up the injection site. It is injected just beneath the skin to smooth out wrinkles such as crows feet. Common fillers include human collagen from a lab, human collagen from the patient, collagen from the donated tissue of dead humans, collagen from cows or pigs, fat cells from the patient, hyaluronic acid from birds or bacteria, synthetic polymers, calcium hydroxlapatite, and miscroscopic plastic beads. The effects of most filler injections will fade with time as the body breaks down the filler. Filler injections side effects may include infections, bleeding, bruising, allergic reactions, lumpy skin, and other problems.

Botox Injections

Botox(r) is the common name for botulinum toxin, a paralyzing toxic chemical that is produced by a bacterium called Clostridium botulinum. It is a registered trademark of Allegan Corporation. Doctors inject small amounts of Botox to temporarily weaken or paralyze the muscles underneath the skin. This then reduces the appearance of wrinkles. The US Food and Drug Administration approved Botox for adults under the age of 65 to treat eye muscle disorders, abnormal neck and shoulder contractions, vocal cord spasms, and frown lines. Many doctors use Botox to reduce other types of wrinkles. The effects of a Botox injection may only last a few months, possibly necessitating repeated injections if a patient does not want the wrinkles to return. Reported side effects associated with Botox include headaches, bruising, drooping eyes, flu-like symptoms, temporary facial pain, nausea, redness at the injection site, and weakness in the muscles of the face. The long term risks of repeated Botox injections are not currently fully understood.

Crows feet appear at the corners of the eyes as a person grows old. These wrinkles happen, because aging skin becomes thinner, drier, and less elastic. Several factors contribute to the appearance of crows feet. There are many different ways to address crows feet. Filler injections smooth out the skin by making the area underneath it plumper. Botox injections reduce crows feet by weakening or paralyzing the muscles just below the skin. Both of these procedures for crows feet may offer only temporary results and have certain side effects that should be discussed with your physician.
