What is Photodynamic Therapy?

Photodynamic Therapy (PDT) is a non-invasive treatment that combines a photosensitising agent with a specific wavelength of light. When applied to the skin, the agent is activated by the light, creating a reaction that selectively targets damaged or abnormal skin cells. This process not only addresses surface-level concerns like acne and sun damage but also stimulates the skin’s natural healing processes, promoting collagen production and improving skin elasticity.

What results can I expect?

Results from PDT can be significant, especially in treating acne, reducing pore size, and diminishing the appearance of fine lines and sunspots. Many patients report smoother, more even-toned skin following treatment. The benefits of PDT accumulate over time, with optimal results typically observed after a series of treatments. It’s important to note that while PDT offers impressive results, it may not be a complete substitute for more invasive procedures in cases of severe skin conditions.

What are the potential risks / side effects of this procedure?

Photodynamic Therapy is generally considered safe, but as with any cosmetic procedure, there can be side effects. Common immediate side effects include redness, swelling, and sensitivity to light —tall of which usually pass within a few days.

During the healing process, some patients may also experience temporary skin peeling or flaking. More serious potential risks include:

• Prolonged skin sensitivity: The treated area might remain sensitive to light for a period after the procedure, necessitating careful sun protection.
• Pigmentation changes: There’s a possibility of hyperpigmentation (darkening) or hypopigmentation (lightening) of the skin, especially in individuals with darker skin tones.
• Infection: Although rare, there is a slight risk of infection, as the treatment involves making the skin more susceptible to light and environmental factors.

If you’re concerned about these risks, it’s best to speak with one of our experienced specialists. They can provide detailed information about the procedure and ensures it’s tailored to your specific skin type and condition.

How do I prepare for the treatment?

Proper preparation is key to maximising the effectiveness of PDT and minimising risks. Here are some steps to follow:

• Consult with a skin specialist at the medical spa. They will evaluate your skin and discuss your goals to ensure PDT is the right choice for you.
• Avoid sun exposure and tanning treatments for a few weeks before the procedure to reduce the risk of adverse pigmentation changes.
• You may be advised to stop using certain skincare products or medications that increase light sensitivity.
• Maintain a healthy lifestyle leading up to the procedure, including staying hydrated and avoiding smoking, to enhance your skin’s healing abilities.

What happens during treatment?

During the PDT session, the photosensitising agent is applied to the skin and left for a period to be absorbed by the target cells. The skin is then exposed to a specific type of light, activating the agent. This process typically takes about 15 to 30 minutes. Patients may feel a mild stinging or warming sensation during light exposure, but discomfort is generally minimal. The procedure is carefully controlled to target only the desired areas, preserving the surrounding healthy skin.

What should I do after my treatment?

After your treatment, it’s best to take the following precautions. These steps will ensure the best results and minimise potential risks:

• Follow any specific instructions provided by the medical spa, such as applying soothing creams or avoiding certain activities.
• Avoid direct sunlight and apply broad-spectrum sunscreen regularly. This helps protect the treated area and prevents hyperpigmentation.
• Use gentle, non-irritating skincare products. Avoid exfoliating agents, retinoids, and other harsh substances for a period as advised.
• Keep your skin hydrated both internally, by drinking plenty of water, and externally, with suitable moisturisers.
• Avoid strenuous exercise and activities that might cause excessive sweating for a few days.
• Attend follow-up appointments to allow your skin specialist to monitor your healing and progress.
