Wrinkles, also known as rhytides, are folds or creases in the skin that appear as a natural result of aging. collagen and elastin, two essential proteins that help support the dermal structure, begin to decline as we age. As collagen and elastin are depleted, our skin loses its youthful volume as well as the underlying support that creates the smooth, supple appearance of our youth. The loss of these proteins allows for creases to form, which can become quite severe over time. Wrinkling is promoted by habitual facial expressions, aging, sun damage, smoking, poor hydration, and various other factors.
A neuromodulator – commercially known as Botox Cosmetic, Dysport or Xeomin – is an injectable drug that has an active ingredient of Botulinum Toxin Type A that is approved by the FDA for cosmetic and medical purposes. Yes, this is the same protein that causes the condition botulism. However, the active ingredient is purified from the source and is therefore a safe, easy way to reverse the hand of time. An injection of botulinum toxin works to penetrate a site-specific nerve terminal to prevent the release of acetylcholine—a natural compound of the nervous system that acts as a neurotransmitter. Without acetylcholine, your nervous system temporarily loses its ability to communicate with the injected area, preventing the muscle from contracting. When the muscles relax, there is gradual smoothing out of the appearance of overlying skin.
As a consequence, there are reduced or erased wrinkles, providing a younger, refreshed appearance. The effects typically last about three months.
