What does PDT for Acne involve?
- Pre-treating the skin for 2 weeks with topical medication
- Photos are taken on the day of treatment
- The skin is degreased with acetone
- 20% ALA is then placed on the face from 30-60 minutes
- The skin is then exposed to an LED light to activate the ALA
- Sun avoidance for 48 hours
How effective is PDT for Acne?
PDT helps to reduce the number of sebaceous glands as well as the bacteria (P. Acnes) that causes acne. The greatest improvement can be seen in those who have cystic or inflammatory acne.
What are the Contraindications for PDT?
PDT is not suitable for those who:
- Are pregnant or breast feeding
- Have a history of Keloid Scarring
- Have taken Roaccutane in the past 6 months
- Have a history of porphyria
What is the recovery time and how many sessions are needed?
Depending on the intensity of your treatment, the recovery time is approximately 3-7 days post treatment.
Best results are attained with 2-4 sessions at intervals between 30-45 days.
What are the side effects of PDT?
Immediately following your treatment session your skin will appear red and sun-burnt, lasting between 3-7 days and you may experience some flaking, crusting or peeling of skin over this period.
Depending on the intensity of your treatment, there may be some mild swelling in the treatment area for 48-72 hours, as well as a sensation of heat, discomfort and/or itching.
**Occasionally you may experience an initial worsening (or flare up) of your acne, about 3-5 days after treatment.
Note that sun exposure MUST be avoided for 48 hours and sunblock MUST be used at all times.
What Light is used for activating the ALA?
At Newin Institute, we use a blue light (LED) of 425nm wavelength to activate the endogenic porphyrins and naturally destroy the P-Acne bacteria, to sterilise the sebaceous follicle and slow sebum production.
