Overview
The National Institutes of Health characterizes wrinkles as a natural sign of aging. They develop as a result of thinning skin coupled with the loss of elastin, collagen and fat under the epidermis. These factors contribute to the aging of the skin and the development of wrinkles. Though there isn’t a medical need to treat wrinkles, a number of products and procedures are available to provide a more youthful appearance to the skin. For wrinkles developing under the eyes, you can often see an improvement with Botox, also known as botulinum toxin or onabotulinumtoxinA.
Identification
The botulinum toxin used in Botox is derived from bacteria. When injected into the muscles under the eyes, it blocks nerve signals used to contract these muscles, according to the American Academy of Dermatology. Without these impulses, the muscles temporarily weaken and relax, improving the smoothness of the skin and lessening the appearance of wrinkles under the eyes.
Time Frame
Results typically take about three to seven days to manifest, and they last anywhere between three and four months, indicates the Mayo Clinic. This means that subsequent sessions are necessary to maintain results. If you fail to go in for further injections, the skin under the eyes returns to its original appearance as the muscles regain their ability to contract.
Effects
While repeated injections are known to maintain a more youthful appearance, they can also lengthen the efficacy of botulinum toxin. The American Academy of Dermatology explains that repeated injections can actually cause treated muscles to atrophy, or thin. When facial muscles thin, the effects of Botox are often longer-lasting, which means fewer treatments are necessary to maintain results.
Risk
According to the Cleveland Clinic, there are very few risks to the use of Botox. Those that do develop are typically temporary. For some people, injection sites experience redness, bruising, soreness or even stinging. Others may develop a slight drooping of the eyelid, though this is relatively rare.
Considerations
If you decide to use Botox to improve the appearance of wrinkles under the eyes, make sure the individual administering the injection is licensed and trained. Improper administration could result in infection or injury to injection sites. Stick with a doctor or dermatologist when having Botox injections.
Expert Insight
The American Academy of Dermatology recommends using Botox in combination with other cosmetic procedures. When used in conjunction with dermal fillers, chemical peels or laser therapy, you can further reduce the appearance of wrinkles and crow’s feet while improving the overall tone and texture of the skin.
