The Pulsed Dye Laser is used for the treatment of prominent blood vessels in the skin, and is used for conditions such as port wine stains (birth marks), thread veins on the face and spider naevi.
The Pulsed Dye Laser emits laser light in very short pulses. The light is absorbed by red blood cells and the blood vessels are destroyed.
The treatment is carried out in the Dermatology Department. At your first consultation, the treatment and any possible side effects will be explained in detail. At this consultation please bring full details of any medications you are taking with you.
On the day of your treatment please do not use any of the following:
If you are wearing make-up on the area to be treated please bring some unperfumed soap with you so that you can wash it off.
A test patch, where a small area of skin is treated, is normally carried out at this stage, to see how the skin reacts to the laser light.
A follow-up appointment is then made 8 to 12 weeks later when, if there have been no problems with the test patch, a larger area of skin will be treated.
A number of treatment sessions will normally be required and these are at about 8 to 12 weekly intervals.
When the laser light hits the skin it feels like a rubber band twanging against it. If needed, some local anaesthetic cream can be applied to the area to be treated, but this must be done at least one hour before the treatment.
Goggles must be worn during the treatment to protect the eyes from the laser light. As soon as the laser light hits the skin the bruising appears and this is entirely normal with this treatment.
Laser treatment cannot be carried out on sun tanned skin so a tan must be allowed to fade before treatment.
Immediately after treatment you can use either Aloe Vera gel or ice packs to ease any discomfort in the skin. Take Paracetamol for any discomfort within the next few days (not Aspirin). Unless the area being treated is around the eyes and there is swelling you can carry on as normal.
The skin may be washed gently. Make up can be used over the treated area 2 or 3 days after treatment if the skin is not broken.
During the treatment period and for 6 months after a sun block must be used on the treated area. Avoid swimming and contact sports while bruising is present.
If you have any concerns or worries at any time, please contact the Dermatology Department on 01709 424514.
