• How Long Does Botox Last?

    Botox is a FDA approved injectable that reduces the muscles that cause wrinkles. Although it’s only FDA approved for certain facial muscles, it’s often injected in areas that may cause aesthetic concern, such as the forehead muscles, the muscles between the eyebrows, and the crows’ feet areas of the face.

    Botox lasts about 3 months, as per FDA labeling. However, it can last longer, depending on the location of the facial muscles, how big the muscles are, and how often it’s given. All of these reasons are anecdotal, or not based on science or evidence. Rather, it’s simply my opinion and some common sense observations.

    Botox works by weakening and temporarily paralyzing muscle. If it’s injected into a thick muscle, the muscles will still function but not as well. This effect is temporary, and your muscle will recover to normal strength and function in about 3 months.

    Depending on the location of your muscles, Botox may last longer in certain areas than others. Botox will tend to work for a shorter period of time in very strong, thick muscles. Botox will last longer, or appear to last longer, if the muscle is thinner. For example, the muscles around the crows’ feet area is not as thick as the muscles in the between the eyebrows, so Botox may appear to last longer in the thinner muscle area.

    If given on a consistent basis, Botox may weaken your muscle, resulting in future injections lasting longer than your first injection. Although anecdotal, it may appear that repeated Botox injections may result in a need to get them less often.
