What can they be used to treat?
The term “Photorejuvenation” used to market these light based treatments can be misleading and confusing.
The capabilities of these machines varies significantly between both types of device (laser/IPL/LED) and between equipment within these categories marketed by manufacturers.
In general, most of these systems can reduce the appearance of some pigmented changes and small thread veins on the face.
Claims for improvement in the appearance of actual wrinkles, any tightening of the skin, or reduction in the appearance of acne scars should be carefully questioned.
Although there is evidence that some of these devices can cause improvement in wrinkles, mild scarring and reduction of large pores you need to clearly define what level of improvement is achievable.
What happens during the treatment and how long will it take to recover?
Depending on the area of skin and type of laser or intense pulsed light (IPL) system used, different treatment procedures may be recommended for you by your practitioner.
Your first discussion with a practitioner should clearly set out your expectations. These should be matched by the likely cosmetic outcome your doctor predicts. He or she should be able to prescribe the most appropriate type of light treatment for you.
A medical history should be taken to ensure that there are no reasons why you shouldn’t have the treatment. You would also normally be asked to read detailed information and sign a consent form at this time which means that you have understood the potential benefits and risks associated with the procedure recommended.
Photographs may also be taken by the practitioner for a “before and after” comparison at a later date.
Treatment procedure
This procedure generally requires no special pre-treatment care.
Anaesthetic cream may be applied 20 minutes or so before the treatment to help numb the skin, and you will be required to wear eye protectors for all laser and IPL machines.
Depending upon the type of system used, you may experience a slight stinging sensation in the area treated during the procedure. The treatment usually takes between 15 to 30 minutes.
Repeat procedures
The procedure may be repeated every few weeks or so for 4 or 5 courses to achieve the desired effect. Afterwards, every 6 months for maintenance, as required.
Recovery time
Most patients will be able to return to work immediately following the procedure.
