INFO
Anti-wrinkle injections are a cosmetic procedure that has been in use for decades. Their main purpose is to soften the appearance of wrinkles on the skin. Sometimes people refer to anti-wrinkle injections as “injectables” or “anti-wrinkle treatments”. For deep lines, your consultant may choose to use dermal filler in conjunction with injectables. The substances used in anti-wrinkle injections are dermal fillers and botulinum toxin Type A, which is available in Australia under several brand names.
When the toxin is injected into the muscle, it blocks the nerve impulses that cause the muscle to contract. As the muscles relax, the overlying skin becomes smoother, resulting in a more refreshed appearance. Anti-wrinkle injections can be given to people aged 18 to 65. In Australia, the cosmetic use of botulinum toxin Type A is primarily approved for treating frown lines between the eyebrows.
Botulinum toxin Type A can also be used for non-cosmetic issues, such as excessive sweating (hyperhidrosis). It can effectively reduce underarm perspiration. Other therapeutic uses include treating conditions such as cross-eyes (strabismus), muscle spasms, and overactive bladder.
The history of botulinum toxin Type A dates back to 1977 when it was first used to treat strabismus. It was approved as an anti-spasmodic agent in the late 1980s. Its wrinkle-reducing effects were first observed in patients being treated for facial muscle spasms. Doctors began using it for aesthetic purposes in 1996, and the FDA approved its cosmetic use in 2002. Since then, it has become a leading treatment for temporarily softening wrinkles.

Good Candidates for Anti-wrinkle Injections

• Those showing early signs of ageing

• People with frown lines or lines that make them look sad, angry, or tired

• Those who cannot undergo invasive cosmetic facial procedures

Contraindications
You must inform your doctor about any medication you are taking to avoid cross-reactions. A skin sensitivity test to the ingredients is also recommended. Anti-wrinkle injections should not be used by:

• Pregnant or breastfeeding women

• People with neuromuscular disorders

• People with egg allergies

Pre-requisites
Some medications (e.g. anti-inflammatories, aspirin) should be stopped at least two weeks before the procedure, as advised by your doctor.

The Procedure

Anti-wrinkle injections are quick and do not usually require anaesthesia. The botulinum toxin Type A solution is injected with a fine needle into targeted facial muscles where wrinkles are most prominent. It can also be injected into other muscles for therapeutic reasons. The procedure causes only minor discomfort and can treat frown lines, crow’s feet, and bunny lines.
The effects typically become noticeable within 3–7 days, with full results in up to two weeks. Results generally last for about six months, after which repeat treatments can be performed. Over time, wrinkles often reappear less severely as muscles remain more relaxed.

Risks and Complications
Side effects are usually mild and temporary. They may include injection site pain, bruising, flu-like symptoms, or headaches. Bruising is the most common but is generally harmless and resolves within a week. Rarely, eyelid drooping (ptosis) or allergic reactions may occur.
Other possible complications include neck pain, dry mouth or eyes, double vision, fatigue, blurred vision, and swelling of the eyelids. Although extremely unlikely, there is a small risk of the toxin spreading beyond the treatment area.
