Intense Pulsed Light (IPL)

Why Intense Pulsed Light (IPL)?

Intense Pulsed Light (IPL) is not the same as a laser. IPL releases pulses of energy through light in a broad wavelength range which produces heat on the skin. A laser projects energy in a very narrow wavelength range which is more focused and therefore produces bleeding (purpura). Thanks to the broad wavelength range, IPL gives less focused heat which reduces the amount of bleeding. The light targets haemoglobin in red blood cells which aims to close the local vessels and reduce the blood supply to the growth of the scar tissue.

Main improvements

IPL can:

  • improve colour
  • improve texture 
  • pliability of the scars 

Adverse effects

 Post-procedural reactions may include:

  • mild erythema 
  • mild swelling

Recommendations

Effects are achieved through reducing pigmentation/vascularisation and therefore the bulk of the scar tissue.

Treatment with this device can be done without anaesthesia. After treatment the blood vessels in the treated area often have a blue-greyish coloration. Following treatment, UV exposure should be avoided for at least 24 hours.

The effectiveness of IPL increases when it is combined with other laser treatments or bipolar radiofrequency. A wide variety of IPL devices are available on the market, not all of them are trustworthy. Regulations for IPL devices are not as strict as those for lasers. Therefore, it is very important to receive advice and treatment from a trained and specialised practitioner with experience in IPL and scars.

F.A.Q.

For which types of scars is IPL suitable?

IPL (Intense Pulsed Light) is suitable for various types of scars, particularly those characterized by excessive pigmentation and vascular components, such as redness or purple discoloration. This is because IPL targets pigmentation and blood flow, making it effective for reducing scars caused by conditions such as acne, injuries, or surgical procedures.

How many IPL sessions are usually needed for noticeable improvements in scars?

The number of IPL sessions needed for noticeable improvements in scars can vary depending on factors such as the severity of the scars and the individual's skin response to the treatment. Generally, multiple sessions are recommended, often ranging from 3 to 6 sessions, with intervals of several weeks to months between each session.

How effective is IPL compared to ablative and non-ablative lasers?

Compared to ablative and non-ablative lasers, IPL is generally less effective for achieving deep skin renewal and reducing deep wrinkles or severe scars. Ablative lasers remove thin layers of skin, making them more effective for reducing severe scars, but they typically require a longer recovery time and can cause more side effects. IPL, on the other hand, is suitable for superficial scars and can effectively address pigmentation and vascular issues. However, it often requires multiple treatments to achieve optimal results.
