Botox has been around for quite some time now, and while it’s most commonly known as one of the best and least invasive ways to relax lines and wrinkles on the face, it can also be used to serve other purposes. Though it has not been approved by the FDA to treat dark circles or bags under your eyes, studies have suggested that it may be an ideal treatment option in some cases.
When a medication is used for a purpose that is not specifically indicated by the FDA, this is considered off-label use. Such uses of drugs have not been studied in the same way as primary uses, and this means there may be more risk to patients. Due to this, a drug company cannot promote any of its drugs for off-label uses, but doctors are allowed to prescribe and use medications in this way if they so choose as long as their patients are made aware of the potential complications and risks.
