Reducing Skin Cancers with Photodynamic Therapy (PDT) in Bondi Sydney

Photodynamic Therapy (PDT) is a revolutionary treatment combining a photosensitising agent with light activation to improve skin texture, tone, and health. Initially developed for medical purposes, particularly treating pre-cancerous lesions like solar or actinic keratosis, PDT has proven invaluable in reducing the risk of skin cancer. It has also gained popularity in the cosmetic realm for rejuvenating skin and addressing various concerns.

What Does Photodynamic Therapy Set Out to Achieve?
PDT is a preventative treatment for individuals with significant sun exposure or a family history of skin cancer, helping reduce the formation of cancerous cells. Additionally, Photodynamic Therapy can help to improve skin quality and address concerns such as:

Sun damage and pigmentation
Fine lines and wrinkles
Acne and acne scars
Rosacea and redness
Enlarged pores

PDT promotes healthier, clearer, and younger-looking skin by targeting these issues. 

How Can PDT Help Reduce Skin Cancer Risks?
Australia has one of the highest rates of skin cancer in the world, with approximately two in three Australians being diagnosed with skin cancer by the age of 70. Prolonged sun exposure, particularly during childhood, significantly increases the risk. PDT effectively targets and destroys pre-cancerous lesions, such as solar keratoses, before they develop into malignant skin cancers. For those who spent significant time in the sun without adequate protection or have a family history of cancer, PDT offers a proactive approach to skin health.

What Results Can I Expect from a Photodynamic Therapy Treatment?
Patients can expect smoother, more even-toned skin with a reduction in fine lines, pigmentation, and redness.
For acne-prone skin, PDT minimises breakouts by targeting sebaceous glands and killing acne-causing bacteria.
When used for pre-cancerous lesions, PDT significantly reduces the likelihood of these lesions progressing to skin cancer.
Most patients notice visible improvements within weeks.

How Does Photodynamic Therapy Work?
PDT involves applying a photosensitising agent (such as aminolevulinic acid or methyl aminolevulinate) to the skin. This agent selectively accumulates in damaged or abnormal skin cells. When exposed to a specific wavelength of light, the agent activates, destroying these cells and stimulating collagen and elastin production. This dual action rejuvenates the skin, enhancing its overall health and preventing disease progression.

How Does Photodynamic Therapy Improve My Skin?
PDT improves skin health and appearance by:

Targeting damaged cells: The photosensitising agent ensures precise and effective treatment.
Stimulating collagen production: The light-activated process boosts collagen synthesis, producing firmer, more youthful-looking skin.
Reducing inflammation: PDT is ideal for conditions like rosacea and acne and for calming redness and irritation.
Destroying pre-cancerous cells: By targeting solar keratoses, PDT prevents their progression to skin cancer.

What Can I Expect During My Photodynamic Therapy Treatment? Is It Painful?
During treatment, the photosensitising agent is applied to your skin and left to absorb for up to three hours. Following absorption, your skin is exposed to a specialised light source. Depending on the extent of damage, discomfort levels can vary. Some patients experience mild tingling or a warming sensation, while more severe cases may require pain management, such as oral medications, Nitronox (happy gas), or the green whistle (Penthrox).

How Long Does a Photodynamic Therapy Treatment Take?
A PDT session typically takes around 90 minutes. This includes time for application, absorption of the photosensitising agent, and the light activation phase. For more aggressive treatments targeting extensive sun damage or pre-cancerous cells, longer application times may be required to enhance results (upwards of 3 hours).

What Is the Downtime After a Photodynamic Therapy Session, and What Kind of Aftercare Is Required?
Downtime varies but is usually minimal. For cosmetic applications, redness, peeling, or sensitivity may last a few days. When treating severe sun damage or pre-cancerous cells, downtime can extend to about a week. Aftercare includes:

Avoiding direct sunlight and using high-SPF sunscreen.
Keeping the treated area moisturised.
Avoiding harsh skincare products for at least a week.

How Many Treatments of Photodynamic Therapy Will I Need?
The number of treatments depends on the condition being addressed. For acne-prone skin, 2-4 sessions spaced several weeks apart are often required. To treat severe sun damage and prevent skin cancer, a single session every 18-36 months is typically recommended, depending on the extent of damage.

How Long After Photodynamic Therapy Will I See Results?
While some improvements may be noticeable within a week, optimal results generally emerge over 4-6 weeks. The most significant changes occur as collagen regenerates and skin heals.

How Long Do the Results Last from a Photodynamic Therapy Session?
Results can last several years, depending on your skin condition and maintenance routine. Regular follow-up treatments and diligent sun protection can extend the benefits.

What Is the Typical Cost of a Photodynamic Therapy?
Costs vary based on the area treated and the condition being targeted. At Beauty by Doctor, a partial face treatment for sun damage starts at $660, while treatments for acne typically cost $495. Pricing is confirmed during a personalised consultation.

Does the Whole Face Need to Be Treated, or Can Just Particular Areas Be Treated with Photodynamic Therapy?
PDT can target specific areas of concern, such as sun-damaged spots or acne-prone regions. This ensures a customised approach tailored to your skin’s needs.
