Photodynamic therapy (PDT) is a medical treatment that utilizes a photo-sensitising molecule such as a topical light-sensitising liquid or cream that becomes activated by light exposure. It can be used to treat abnormal skin cells including pre-cancerous cells, sun-damaged skin, actinic keratosis, acne and rosacea.

The results of PDT include improved skin tone, smoother skin texture, and reduced appearance of pores.


“Rosacea had really dented my confidence and self-esteem; PDT has really helped to to improve it and keep it under control.”

What can photodynamic therapy do for me?

PDT can help remove sun damage, fine lines, and blotchy pigmentation. The treatment can also reduce oil gland function and so is helpful in treating acne and rosacea.

Who is suitable?

You will be given a full consultation with Dr Joney De Souza, who will take your medical history and assess your suitability for the treatment.

What’s the treatment like?

Skin is cleansed to remove any excess oil and impurities so that it may absorb the applied topical medication more readily. A topical photo-sensitiser liquid or cream is then applied to the treatment area (this may be the entire face, scalp, back of the hands, etc).

After being allowed to dry and absorb for up to 20 minutes, the medication is then activated using a specific wavelength light source for approximately 20 to 40 minutes.

Patient experience during PDT varies, but can include sensations of warmth, tingling and heat. The treatment area is then cleansed and a sunscreen applied. Instructions will be given on how to care for the skin at home.

What happens afterwards?

Patients should avoid sun exposure for at least 36 hours. Mild skin redness and peeling can be expected for one or two days following treatment, but patients can typically go about their daily activities
