Yes, when used by appropriately qualified practitioners, these treatments are relatively very safe. All practitioners at our doctor-led clinic have had certified training specifically, with some also having higher qualifications in laser treatment such as the core of knowledge. Unlike certain UV rays from the sun, the bright light used in treatments is not thought to be cancer-forming, as it utilises visible and infrared light that is outside the ultraviolet range that causes sunburn, skin cancer and ageing of the skin.
The flashes of bright light that are produced may damage the eyes, so goggles have to be worn during the treatment. The treatment is generally well tolerated but some patients find it more uncomfortable. Exposure is limited to an extremely short flash that feels like the warm flick of a rubber band. Occasionally there is some swelling that will subside in a day or two. Bruising is unlikely but if it occurs, it will settle in a few days. There is a small chance that pigment changes may occur in the skin, either dark marks (hyperpigmentation), or pale marks (hypopigmentation). This is usually temporary and typically self-resolves. To help reduce the risk of this it is very important that sun exposure is avoided for 4 weeks before your treatment and throughout the course of treatment. Crusting and blistering may rarely occur after the treatment, but this is best left to heal undisturbed so as to reduce the risk of scarring. It is important that you follow any aftercare instructions carefully. This form of treatment is extremely popular in many countries and most patients tolerate it very well when performed at an appropriate clinic.
