The natural ageing process causes skin to lose both volume and elasticity. Muscle contraction during facial expression, such as frowning and smiling, causes the skin overlying the muscle to crease. Loss of elasticity means that the skin does not bounce back in the same way it once did, and loss of volume means that these wrinkles become increasingly prominent, even when the muscle is relaxed. This leads to the formation of facial lines and wrinkles visible at rest, which are identified as a classic sign of ageing.

Small Botulinum toxin injections under the skin help to relax the muscles responsible for causing these facial lines and wrinkles. By preventing muscle contraction, the skin overlying the muscle does not crease when making certain facial expressions, and therefore the skin stays smooth and the expression appears more youthful. This helps to prevent facial wrinkles from forming if they have not yet become visible at rest, and helps to smooth out and reduce the appearance of wrinkles which have already become prominent.

At Brookside Dental, we use Azzalure® rather than the more commonly known Botox®. Both products are compounds of Botulinum toxin, however experience has lead us to favour the results using Azzalure®.

Treatment Areas

Frown lines

These are the vertical wrinkles which form in the centre of the forehead between the eyebrows. These significantly deepen when frowning or squinting, and can commonly lead to in a vertical line in the skin visible at rest even when the muscle is relaxed.

Botulinum toxin treatment helps to relax this muscle and therefore prevent this line from forming or becoming deeper, and can help to smooth out a line which has already formed. Treating the frown area also helps to achieve a subtle eyebrow raise and thereby help to open up the eyes and give a fresher look.

Smile lines

These are the horizontal lines which spread out from the corner of the eyes when smiling.
Botulinum toxin treatment helps to relax the muscles around the outside of the eyes, thereby preventing these lines from forming even when giving a big wide smile.


Forehead lines

These are the horizontal lines which form across the forehead when raising the eyebrows. When these lines become present at rest, they are often very noticeable and can cause un-even tan lines or difficulty with make-up application as it falls into the creases.

Botulinum toxin treatment helps to relax the forehead muscle and thereby stop these lines from appearing when the eyebrows are raised. Existing lines will be smoothed out offering a more youthful and rejuvenated appearance.


Botulinum toxin injections are very small injections using insulin needles, therefore they are virtually painless and the most that can be felt is a small pinprick or slight discomfort as the needle enters the skin.

Treatment using Azzalure® usually starts to take effect between 2-5 days following the injections, with the full effects visible at two weeks post-treatment. The effects will then last for approximately 3 months in the forehead and around the eyes, and up to 5 months in the frown area, however this is also dependent on the strength of your facial muscles.

Like all medicines, Azzalure® can cause side effects, although not everyone experiences them. Any reactions are generally minimal, temporary, and typically relate to the injection itself. There is possibility of bleeding, bruising, redness, itching, rash, or stinging at injection sites, and headaches may occur for the first couple of days following treatment. There is also a small possibility of slight drooping of the eyelid or visual problems. Other potential side effects are listed in the Azzalure® patient information leaflet. Please ask your practitioner for this at your consultation appointment.

Prior to injecting, your practitioner will remove all make-up and the skin will be cleaned. We recommend to avoid drinking alcohol 24 hours before treatment as alcohol intake can promote more bleeding and bruising following the injections.

Your practitioner will tell you how to look after your skin following the treatment, but outlined below is the key information.

For at least 4 hours following treatment:

  • Keep upright
  • Do not bend excessively

For 12 hours after treatment:

  • Avoid extreme facial expressions
  • Avoid excessive alcohol consumption
  • Avoid wearing make-up

For 2 days after treatment:

  • Do not rub or massage the treated areas as this may displace the injected solution into nearby muscles
  • After washing the face, pat the skin dry very gently with a soft towel

For 2 weeks after treatment:

  • Avoid exposure to strong sunlight, very cold temperatures, saunas and steam rooms
  • Do not have any beauty treatments on your face e.g. facials, massages, eyebrow treatments
