For intense pulsed light treatment a thin layer of chilled gel is applied to the skin to aid light absorption by the vessel. The light applicator is then placed on the skin and a short pulse of light is released. The applicator is then moved to the neighbouring area and the process is repeated until the entire area is treated. The chilled gel is removed and the area cooled. A similar process is carried out for laser treatment except the chilled gel is not required. During treatment, protective eye wear will be provided.

Typically 3 to 5 treatments are needed for maximum results, though small lesions may clear in just a single session. Repeat treatments are spaced every 4 to 6 weeks.

Treatment is mildly uncomfortable but there is no need for anaesthesia and the procedure is actually quite quick. Sensations vary but most describe it as a very quick hot pin prick.

After treatment the area may feel warm for a few hours. Rarely some delicate skin areas such as the cheeks or decollete can be red and slightly swollen for up to 48 hours. Though very rare, there is a chance a small blister may form and there could be temporary lightening or darkening of the skin.
