Dr. Esho says the professionals likely to opt for this look tend to be lawyers, bankers and psychiatrists.
The Botox they use, also dubbed Protox, is common among people who have a "hyper-expressive face" and what to still appear at ease, according to Dr. Esho.
"Over time I've noticed a new wave of patients who are pursuing Botox to give them reduced or minimal expression. I've seen a particular trend in professions such as law and banking, where patients in these careers feel that they will be taken more seriously," Dr. Esho said in a recent interview.
In one case, a New York-based plastic surgeon reportedly described how her friend, who is a psychiatrist, got Botox as she struggled to appear non-judgmental while her clients spoke, a key requirement of the profession.
"My friend, who is a psychiatrist, said she spends so much time while patients are talking to her trying to not contract [her facial] muscles, so as to not appear judgmental, that she barely hears what they're saying," Dr. Dara Liotta said in a recent interview.
There are however health reasons behind using Botox, many people opt for this type of treatment in order to stop sweating. Again, this physical sign could indicate nervousness, a trait that most professionals would prefer not to have.
"I have some people come in who are in the public eye and have the sweaty brow or sweaty forehead and they want it just for that reason," dermatologist Dr. Roy G. Geronemus said in a recent interview.
"They're embarrassed because it shows that they're nervous," Dr. Geronemus added.
Although the number of plastic surgery procedures in the UK dropped by 40 percent following the Brexit referendum, non-surgical interventions such as facial injections have become increasingly popular.
