Unlike lasers, IPL devices produce a broad spectrum of light in a range of wavelengths. The emitted light is further adjustable through the use of filters, allowing any skin colour to be treated. This versatility allows the characteristics of the light energy to be adjusted according to each patient’s skin type, specific condition and location of the condition.
Another difference is in the area that can be treated in one session. Generally IPL treatment heads are up to eight times larger than the small spot produced by lasers, so treatments are quicker but not as targeted as laser.
In terms of safety, the two types are similar, but with lasers both the practitioner and the patient need to use eye protection. Light from IPL systems may also be harmful to the eyes so protection should be worn for IPL treatments.
While lasers and IPL treat many of the same conditions, IPL is a single technology for a multitude of applications – from unsightly veins and birthmarks to ageing and sun-damaged skin, unwanted hair and rosacea.
During the procedure pulses of intense light are fired at the skin through varying filter which isolate specific wavelengths of light. Various targets (such as haemoglobin in the blood to remove vascular lesions, or melanin to treat hyperpigmentation) are preferentially absorbed, heated and selectively destroyed by certain light wavelengths (called selective photothermolysis) without damaging surrounding tissues.
IPL treatment cannot typically address extensive sun damage and skin discolourations but it can reduce surfaced capillaries, brown spots, as well as help revitalise and even out the overall complexion. Typically four to six treatments are required for optimal results.
The usual downtime with IPL modalities is minimal to none, depending on the intensity of the treatment. However, full recovery can take around two weeks in some cases. Straight after IPL a slight burning sensation can occur for a few hours but there is generally little discomfort. Temporary discolouration can occur for around three to four days after the procedure and will flake off slowly. Short-term side effects include reddening of the skin (erythema), temporary bruising and oedema. Reactions such as scabbing and blistering are possible though rare. It’s important to protect skin from UV light with daily sunscreen application.
