Here's the thing, though: Because the drug has only been around for 30 years, there aren't a lot of stories about the long-term effects of Botox. Which are legitimate concerns.
To find answers, that have been consulted Weinstein, as well as the legendary dermatological surgeon Patricia Wexler, MD. Curious about the effects that Botox can have on your skin after 10 or more years of use?
Long-Term Effects of Botox...
* Your skin might become visibly thinner
Wexler says that some patients complain of a visible thinning of the skin after many years of Botox use. That might mean exposure of subdermal veins between areas of normal thickness. This isn't common, but Wexler says that patients who start Botox "too early," like in their early 20s, can be at risk for this side effect. In these cases, "The skin of the forehead [can] get prematurely thinner, and muscles weaker," she says. Sometimes, after many years of use, this can even result in the look of heavier brows and eyelids, "making the toxin actually more difficult to continue using."
* The muscles will weaken from lack of use
If you didn't move your legs for 20 years, eventually those muscles would shrink and become quite weak. The same thing can happen to the muscles in your face. "If used regularly, over a prolonged period of time, without interruption, eventually the muscle will atrophy from lack of use," says Wexler. That's not to say your entire face will atrophy: "As the Botox is injected in discrete locations on the face, eventually only those treated muscles will atrophy, leaving other muscles to maintain full volume," Wexler maintains.
The weakening of those wrinkle-forming facial muscles isn't inherently bad, but in some cases, side effects can occur…
* Mild discoloration or a "wavy" texture could appear
Again, not typical, but Wexler says that with the skin thinning, some patients notice "a visible waviness of the skin overlying the muscles treated," as well as discoloration. "On expression, the forehead may even appear like hills and valleys," she says.
Luckily, this side effect is totally preventable. "[It] can be avoided by changing the pattern of injection to give smaller amounts of toxin in a more uniform distribution to get an identical effect without this problem, or stopping the toxin for an extended period of time," Wexler says.
* Your skin will look brighter and less wrinkled
Aside from what "can" happen after long-term use of Botox, one thing is for sure: "If you continuously get Botox for 10+ years you will certainly look much younger and have fewer wrinkles," promises Debra Jaliman, MD, a New York City-based dermatologist and author of Skin Rules: Trade Secrets from a Top New York Dermatologist. "Your skin will look much smoother and the appearance of fine lines and deep wrinkles will be greatly diminished."
Weinstein agrees, adding, "You can age gracefully without having any wrinkles on the forehead, glabella, or around the eyes, when you may have had the propensity to develop them. That’s the beauty of Botox."
Another point is Long-Term Effects of Botox According to FDA and medical research, Botox® injections paralyze muscle functions to stop signs of aging and this, in the long run, can cause people to experience loss of muscle control and also decrease of strength in the muscle area which has been injected with Botox®. Don't forget to consider the long-term effects of Botox.
