Ageing and Wrinkles

As a person ages, their skin cells divide more slowly, and the inner skin (dermis) thins. Important proteins in the body, which allow skin to stretch and give volume, decrease. As a consequence, skin loses its elasticity, sagging to form furrows or wrinkles. The skin’s ability to retain moisture also diminishes as sweat and oil-secreting glands degenerate, leaving skin dry and scaly.

In addition, habitual facial expressions, such as frowning and smiling, form characteristic lines due to repeated small muscle contractions.

Skin can also age prematurely due to prolonged exposure to ultraviolet (UV) radiation from the sun (photo-ageing). Sun damage is one of the most important causes of skin ageing and skin cancer. Protecting the skin from sun damage, through the use of sunscreen and protective clothing, is one of the most important ways to reduce wrinkles and prevent skin cancer. People who work outdoors are obviously at greatest risk of UV related skin damage. Certain complexions, especially those with red or blond hair and fair skin, are more susceptible to photo-ageing that those with darker skin and hair. Other environmental factors, such as cigarette smoke, may accelerate skin ageing by producing free radicals. Weight loss can also contribute to wrinkles by reducing the volume of fat cells that cushion the face, causing the skin to sag.

Dynamic versus Static Wrinkles

Dynamic wrinkles are lines that occur when we use our muscles to form facial expressions. Young skin springs back to its original position at rest when we finish making the facial expression. As we age, dynamic wrinkles remain on the skin to form static wrinkles, due to the factors described earlier.

Treating Wrinkles: Anti-Wrinkle Cosmetic Injections

At WPRS, Anti-Wrinkle Cosmetic Injections are used to treat dynamic wrinkles by relaxing the wrinkle-causing facial muscles. Once relaxed, the muscle cannot contract. This gradually smooths wrinkles and prevents worsening of them. After injection, it takes 2 to 3 days to start working, up to 14 days for full effect. Treatment typically lasts 2 to 4 months and depends on the dose administered and the patient’s facial muscle strength. The most common areas for use are in the upper face, into the muscles associated with frowning (above brow), smiling (around eyes, ‘crow’s feet’) and looking surprised (forehead). Treatment at WPRS is individualized, with Cosmetic Physician, Dr Emma Renouf, generating a treatment plan based on each patient’s unique facial features.

Potential Side Effects

The side effects of these wrinkle treatments are generally temporary and localised to the area of injection. Mild discomfort, swelling, bruising and redness are common. Full explanation of the procedure, side effects and expected treatment outcome occurs prior to treatment and pre-treatment photos recorded confidentially.

At WPRS, Dr Emma Renouf administers these injectable treatments. She is a trained Cosmetic Physician with a detailed knowledge of facial anatomy and the ageing process that causes wrinkles, and tailors treatments to the patient’s unique facial structure, unlike some clinics where are blanket “formula” is applied.
