Anti-Wrinkle Injections
Reduces the appearance of wrinkles on the forehead, around the eyes and mouth, and elsewhere on the face, leaving a smoother, more youthful-looking complexion.

How it works
The muscle, not the surface.
Anti-wrinkle injections focus on the facial muscles that create wrinkles and expression lines, those responsible for forehead lines and crow's feet. The treatment reduces muscle activity in specific areas, preventing wrinkles from becoming more pronounced and allowing the skin to appear smoother and firmer. It works by blocking nerve signals to the muscle, giving results that arrive quickly and improve the skin's appearance over the longer term.
Expression lines etched by years of repeated movement soften once the muscle relaxes, and regular treatment limits that movement before deeper lines form.
Expression linesRelaxing the masseter muscles slims the lower face into a more sculpted jawline, and eases the tension that comes with clenching.
Jawline slimmingInjections into the underarms, hands, feet or face reduce excessive sweating, a medical use of the same treatment, not a cosmetic one.
HyperhidrosisDosage and placement are assessed against your own facial anatomy by a consultant dermatologist. The aim is a smooth, natural result, not an absence of expression.
Natural movementWhat areas can be treated
A versatile treatment.
Anti-wrinkle, or muscle-relaxing, injections address a wide range of aesthetic and medical concerns. Commonly treated areas include:
Forehead lines
Smooths the horizontal lines across the forehead, often caused by raising the eyebrows.
Crow's feet
Reduces the appearance of fine lines around the eyes, typically formed from smiling or squinting.
Frown lines
Targets the vertical lines between the eyebrows: the "11 lines" caused by frowning or concentrating.
Bunny lines
Treats the lines at the sides of the nose, visible when scrunching the nose.
Eyebrow lift
Lifts and shapes the eyebrows, creating a more youthful, refreshed appearance.
Smile lines
Softens the lines around the mouth, reducing the appearance of sagging.
Neck bands
Reduces the visible bands or wrinkles in the neck, commonly referred to as "turkey neck".
Chin dimpling
Smooths the dimpled or "orange peel" texture on the chin.
Jawline slimming
Relaxes the masseter muscles to create a more sculpted, slimmer jawline.
Excessive sweating
Injected into areas such as the underarms, hands, feet or face to reduce excessive sweating (hyperhidrosis).
Calves
Slims the calves by relaxing the calf muscles, creating a more contoured leg shape.
Shoulders
Injected into the shoulders to reduce muscle tension, relieving discomfort and improving the appearance of the area.
“Anti-wrinkle treatment is anatomy, not units. Where the muscle pulls, and how strongly, is what decides the dose, and that varies from face to face.”
A common question
Anti-wrinkle or filler?
Dynamic wrinkles caused by facial expression: frown lines, crow's feet and forehead lines formed by repeated movement.
Relaxes the targeted muscle so the skin above it creases less.
Static wrinkles and volume loss, which form as collagen and elasticity decline.
Restores volume and smooths lines that remain when the face is at rest.
Deeper lines and static wrinkles may need filler alongside anti-wrinkle treatment to restore lost volume.
Both dynamic and static wrinkles addressed: a balanced, comprehensive anti-ageing plan.

Your journey, step by step
What actually happens.

Consultation & assessment
Your facial movement is assessed, your medical history reviewed, and a bespoke plan created: areas, units and a detailed cost breakdown, agreed before treatment.
You commit to nothing at this stageThe treatment
A fine needle is used, so most patients experience only mild discomfort. The treatment typically takes less than ten minutes to administer, and any bruising or swelling is minimal and settles quickly.
Back to your day immediatelyThe result appears
Results usually appear within a few days, with full effect visible at about two weeks. Smoothness and wrinkle reduction become more noticeable as the treated muscles relax.
Avoid exercise and sun exposure briefly after treatmentMaintaining it
Results typically last up to six months depending on the individual and the area treated. A follow-up every few months maintains the effect, and regular treatment can prevent deeper lines forming by limiting repetitive muscle movement.
Aftercare
For the best result.
It is advisable not to lie down for three to four hours after the procedure, to avoid affecting the injection site.
Swelling, bruising and slight itching in the injection area are natural and will disappear over time.
Avoid massaging the treated area, using a sauna, or strenuous physical activity for a few days after treatment.
Protect the treated area from excessive sun exposure, and refrain from alcohol and blood thinners for a few days to reduce the risk of bruising.

Both reduce the signs of ageing, but anti-wrinkle injections work by relaxing targeted muscles, reducing dynamic wrinkles caused by facial expression. Dermal fillers restore volume and smooth static wrinkles, which form as collagen and elasticity are lost.
They are most effective for dynamic wrinkles such as frown lines, crow's feet and forehead wrinkles caused by repeated movement. Deeper lines and static wrinkles may require additional treatment, such as filler, to restore lost volume.
