"PDT effectively treats acnes, psoriasis and
other blemishes through light exposure."
PDT (Photodynamic) Therapy involves three key components; a photosensitizer, a light source, and tissue oxygen. The specific wavelength of the light source excites the photosensitizer applied to the target area to produce reactive oxygen species, which leads to the chemical destruction of tissues. PDT is widely used to treat skin conditions such as acne, psoriasis, and skin cancer by applying the photosensitizer topically and locally exciting with a light source. Compared to normal tissues, defective tissues actively uptake and accumulate photosensitizers, which makes them vulnerable to PDT treatment. Blue light of wavelengths between 407nm and 420nm heat up blue pigments in the acne bacteria and burst their membrane, which leads to 99.99% of all acne bacteria to die within 48 hours of light exposure. Red light heats sebaceous glands that cannot be reached by blue light and shrink them to stop the production of new whiteheads and blackheads.
Procedures of PDT Therapy
1. A photosensitizer is applied to your skin and left for 15~60 minutes.
2. A special light is applied to the skin for 8~10 minutes to activate the photosensitizer.
Advantages of PDT Therapy
• Significantly improves acne breakouts and skin texture
• Softening and reducing acne scars
• Rapid treatment of acne lesions all over the face
Post Management of PDT Therapy
• You may experience redness and/or peeling for several days after the treatment.
• 2~3 sessions with the interval of 2~3 weeks are required to obtain optimal result.
• Avoid sun exposure as you are photosensitive for about 24 hours after PDT treatment.
• Avoid sun exposure or tanning for 1 month prior to the treatment as well.
