What Causes a Wrinkle and How Does a Wrinkle Relaxer Work?


In prior posts we have discussed the importance of skin care and adjunct procedures to prevent premature aging, a hallmark sign of which is wrinkling.

But, how do wrinkles form?

In the simplest explanation, wrinkles develop due to a loss of real estate. Consider your forehead. The only muscle found in the forehead is the frontalis. Responsible for raising your eyebrows, when the frontalis muscle contracts, its fibers shorten, and the eyebrows are pulled upward. What happens to your forehead skin? With the now shortened frontalis underneath, the skin of the forehead compensates and accordions into horizontal wrinkles. A similar phenomenon occurs to create crow’s feet and the “11’s” between a person’s eyes.

So, how do wrinkle relaxers work?

There are three main wrinkle relaxers on the market today: Botox, Dysport, and Xeomin. All three use the same compound, BTX-A, whose cosmetic effects on wrinkles was first recognized in 1989. Botox was the first approved wrinkle relaxer, and is the most commonly used today.

In order for a muscle to contract, a nerve must first release small packets of chemicals, termed neurotransmitters, into the space between the nerve and the muscle. Receptors on the muscle then grab on to these neurotransmitters leading to muscle contraction. Contrary to popular belief, Botox does not directly cause muscle paralysis. Botox is instead absorbed by the nerve, and prevents release of the neurotransmitters, thereby preventing muscle contraction. After 3-4 months, Botox levels within the nerve have dropped low enough that neurotransmitters are again released, resuming muscle contraction.
