Photodynamic Therapy (PDT) with MultiLite® in London
Consultant-delivered photodynamic therapy in London using MultiLite® technology. We offer both indoor daylight PDT and classic PDT for actinic keratosis, early non-melanoma skin cancer, and severe sun damage. Patients visit us from Maida Vale, St John’s Wood, and Paddington for precise, low-downtime skin cancer care.
Introduction
Photodynamic Therapy (PDT) is a two-step medical procedure that uses a photosensitizer cream—such as Metvix®—applied to the skin, followed by exposure to specific light, which activates a therapeutic reaction. GME’s MultiLite® system enables both conventional red-light PDT and innovative indoor daylight PDT (ADL-PDT), delivering treatment that is more comfortable and efficient.
Unlike natural daylight—which is weather-dependent—the MultiLite® delivers controlled blue, yellow, and red light wavelengths indoors to activate the photosensitiser efficiently across a large treatment area (up to ~500 cm²) in about 35 minutes. This makes it highly suitable for treating extensive sun-damaged skin, actinic keratoses, and cosmetic concerns like pigmentation, acne, and ageing.

How the technology works (technical detail)
PDT involves three components: a photosensitiser, light of specific wavelengths, and tissue oxygen, combining to create reactive oxygen species that selectively destroy abnormal cells.
The GME MultiLite® delivers sequential blue (~420 nm), yellow (~585 nm), and red (~635 nm) LED light to activate the photosensitiser across increasing skin depths, simulating daylight exposure in a controlled environment.
Treatment process step-by-step
- Consultation: skin assessment and PDT suitability check with a consultant dermatologist.
- Photosensitiser application: cream applied to the treatment area and allowed to absorb.
- Light exposure: MultiLite® is positioned to deliver LED light for ~35 minutes over a large area.
- Aftercare: sun avoidance and topical support guiding healing.
Applications & Benefits of GME MultiLite® PDT
- Actinic keratoses (pre-cancerous sunspots).
- Superficial basal cell carcinoma & Bowen’s disease (SCC in situ).
- Diffuse sun damage, pigmentation, and uneven tone.

Recovery & downtime
There may be mild redness, mild swelling, or crusting for 2–5 days. Patients usually return to routine quickly with proper post-care.
Safety & side effects
MultiLite® PDT is typically less painful than traditional high-fluence red-light protocols. Skin photosensitivity may persist for ~48 hours—avoid sunlight and use sun protection accordingly.
Before & After Results
Initial results include reduced redness and a healthier texture within days. Over 2–4 weeks, lesions flatten and fade; skin tone improves and acne lesions decrease. Long-term texture and pigmentation benefits emerge over subsequent months.
