Anti-wrinkle injections

What are anti-wrinkle injections?

• Anti-wrinkle injections work by blocking nerve signals to muscles, which temporarily relaxes specific muscles in the face. When these muscles are relaxed, the overlying skin appears smoother, which helps reduce the appearance of fine lines and wrinkles - especially those caused by repetitive movements like frowning, squinting, or raising the eyebrows.

• The effects of these injections are temporary and require ongoing treatment for maintenance.

What are the common areas treated?

• These include:

  • Forehead wrinkles

  • Frown lines

  • Crow’s feet

  • Plastysmal bands (bands in the neck)

  • Hyperhyidrosis (excessive sweating)

How long does the effect last for?

• The effects last for 3-4 months on average. Ongoing treatments are required to maintain the effect.

Who shouldn’t have anti-wrinkle injections?

• It is generally not recommended if:

  • You are pregnant or breastfeeding.

  • You have neuromuscular conditions e.g. multiple sclerosis, myasthenia gravis, Bell’s palsy.

  • You are on certain medications e.g. aminoglycoside antibiotics, penicillamine, calcium blockers.

What are the possible side effects?

• These might include persistent discomfort at the injection sites, redness, swelling or bruising. Headaches can occur and you may take paracetamol for this. Other side effects can include facial muscle weakness, drooping of the eyelid or eyebrow, rashes and allergic reactions.
