Procedure
A solution is applied to the skin which is preferentially taken up by sundamaged
or inflamed cells and makes them more sensitive to light. Laser, IPL or other
constant light sources may be used to activate the solution and destroy these abnormal cells. May be used for superficial non-melanoma skin cancers, pre-cancers and acne.
Length
The solution is applied for between 1 hour and overnight. Light is applied for
up to 20 minutes.
Anesthesia
Usually cold air.
Side Effects
Sensitivity to light, especially in first 2 days after treatment. Exaggerated
swelling and redness in some cases. Incomplete clearance of sun damage may require
further treatment.
Recovery
Redness, swelling and crustiness for up to a week for the face, longer for the
body - degree depends on the amount of damage to be treated.
Duration
Skin checks for skin cancers should still be routine. Effects on acne are very
variable.
