What is Photodynamic Therapy?

Commonly referred to as: PDT, light therapy for skin cancer, non-surgical skin cancer treatment, red light treatment, actinic keratosis light therapy.

Photodynamic therapy (PDT) is a well-established non-surgical treatment for precancerous skin lesions and low risk skin cancers that is increasingly popular across the UK. It involves applying a special light-sensitizing gel to abnormal skin cells, which are then exposed to a targeted light source. This process selectively destroys damaged cells while leaving healthy tissue untouched.

PDT skin treatment is most often used for pre-cancerous lesions and superficial skin cancers, offering an effective solution without the need for cutting or stitching. At Apex Skin Clinic, our consultant skin cancer specialists and consultant dermatologists deliver photodynamic therapy UK patients can trust — providing safe, clinically effective care for a range of early skin cancers and cosmetic concerns.

Because photodynamic treatment preserves the surrounding skin and avoids scarring, it is especially suitable for visible areas such as the face, scalp and chest. It can also treat large areas at one time in a single session, providing efficient and effective treatment.

What Are The Benefits Of Photodynamic Therapy?

PDT skin treatment offers many advantages. It is completely non-invasive, with no incisions or stitches required. This makes it particularly beneficial for treating areas such as the face, scalp, chest and hands, where preserving the skin’s appearance is important.

Because photodynamic treatment targets only abnormal cells, it spares healthy tissue and minimises the risk of scarring. Patients can often have multiple lesions treated during a single session, improving efficiency and reducing overall treatment time.

PDT also provides a valuable option for patients who prefer not to undergo surgery, or who may not be suitable for surgery due to medical conditions. It is a well-established, effective treatment with excellent cosmetic outcomes for carefully selected skin cancers and pre-cancerous lesions.

Who Should Consider Photodynamic Therapy?

If you have been wondering what is PDT skin treatment?, it is designed to treat pre-cancerous changes and early skin cancers on the skin’s surface. We most commonly use PDT light treatment for skin to manage actinic keratosis, Bowen’s disease (squamous cell carcinoma in situ), and superficial basal cell carcinoma (BCC) in patients where surgery may not be suitable or preferred.

Some patients are offered PDT skin treatment when surgery might affect cosmetic outcomes, or where multiple lesions need treating. The treatment is also occasionally used to rejuvenate sun-damaged skin and reduce inflammation in selected cases of acne. However, PDT is not appropriate for invasive cancers or large nodular BCCs, where surgical management remains the best option.

How Photodynamic Therapy Works

Photodynamic therapy works by applying a photosensitising gel directly to the treatment area. This cream is absorbed by abnormal skin cells, making them highly responsive to light. After a waiting period of around three hours, a controlled PDT light treatment for skin is performed using either red or day light, depending on the type of lesion being treated.

The light triggers a chemical reaction within the sensitised cells, causing them to break down naturally over the following days and weeks. The healthy surrounding skin remains unaffected.

As the skin heals, old damaged cells are replaced by new, healthy skin — leaving behind a clearer, smoother appearance. Because UK dermatology guidelines recommend this targeted approach, it helps patients avoid unnecessary surgery, particularly in cosmetically sensitive areas.
