Anti-Wrinkle Injections

While anti-wrinkle injections are predominantly used to soften lines and reduce the appearance of wrinkles, they can also be used to resolve and prevent excessive sweating.

What Is Hyperhidrosis?

Hyperhidrosis is a neurological disorder in which sweat glands are overactive, causing excessive sweating. This can occur throughout the entire body, or in isolated areas such as the hands, feet, underarms, or groin. This can have severe impacts on quality of life, causing distress and self-consciousness in hyperhidrosis sufferers. Excessive sweating can be worsened further in stressful situations or in response to heat, alcohol, exercise, and spicy food. Anti-wrinkle injections can be administered to the face or other areas of the body and stop the sweating in that region for up to 6 months.

How Does It Work?

Anti-wrinkle injections act directly on the nerves in the injected area. When used to combat signs of ageing in the face, the target nerves are those which are attached to facial muscles. Botulinum toxin, the substance used for anti-wrinkle injections, suspends the connection between the nerves and facial muscles in the treated area, therefore reducing muscular contractions and lessening expression lines. This same concept applies to excessive sweating, but instead of suspending the connection between nerves and muscles, this treatment suspends the connection between nerves and sweat glands. This prevents the sweat glands from being over-activated, therefore reducing (or even stopping) sweating in that area.

How Long Do They Last?

The longevity of anti-wrinkle injections is different in every individual, and can be influenced by area of treatment, the depth that the botulinum toxin is administered, and the quantity used. Typically, 100 units of toxin is administered to each underarm. The most effective depth of the injections can be different across individuals, and therefore may require some trial and error. Generally, sweating is significantly reduced for 3-6 months.

What Are The Risks?

There are minimal risks associated with anti-wrinkle injections. As per all injectable treatments, there is a risk of bruising, bleeding and/or swelling at the injection site, and infection if care instructions are not followed. An additional risk of hyperhidrosis injections is the potential for compensatory sweating. This means additional sweating in other areas to compensate for the reduction in the treated area, though this side effect is extremely rare.
