Is IPL safe to use on ethnic or darker skin?

This depends on what you are looking to treat with IPL. We currently use the Palomar Icon MaxR Intense Pulse Light(IPL) hand piece on ethnic/darker skin types when treating for hair removal. Pre-treating and post treating with a lightening agent such as 4% hydroquinone helps reduce the risk of post inflammatory hyperpigmentation(darkening of the skin).  Ethnic/darker skin types may require more treatments based upon the settings required to safely treat, but it can be done and with excellent results. However, if IPL is being used for photofacial treatments to address conditions such as sun damage, vascular lesions, or acne, patients of Fitzpatrick 1-3  are the best candidates. The most effective treatments are spaced 3-4 weeks apart. And yes, IPL can burn any skin type based on the settings used, experience of the practitioner or sun exposure prior to treatment.  

African American skin tones and skin that has more pigment or melanin is mire prone to developing both hyper and hypopigmention (unwanted darkening or lightening of the skin) that may be permanent. Also, darker skin types may be at higher risk of burn from the treatment. Depending on skin type, a "test spot" can be performed prior to proceeding with treatment to assess how your skin responds to IPL. Both side effects of hyper and hypopigmentation are unpredictable and can happen at any time in the course of series of treatments. Please consult with an expert laser provider to assess your skin's specific needs to develop a customized plan that is both safe and efficacious for you

Hi Ali.  IPL can be safe or unsafe for most skin types.  The key is how the practitioner is using it and what skin condition is being treated.  The IPL has a broad spectrum of light and uses "cutoff filters" to restrict certain types of light.  While these cutoff filters generally make the device safer, they also lower the power.  So, when the user increases the power to treat more resistant lesions (sun damage, veins or wrinkles), the risk goes up.  At our practice, we do not currently offer IPL because we have lasers that can accomplish our patient's goals more quickly, easily, safely and permanently with lasers rather than IPL.  Examples of the conditions we treat and the outcomes can be found at the link below.  

IPL is difficult on darker skin types. As a general rule, the darker the skin color, the less safe it would be. That's because unlike laser, IPL emits a broad spectrum of light, meaning multiple wavelengths. Shorter wavelengths tend to target melanin in the skin, which is obviously more abundant in a darker skin type. Instead of IPL, I'd be more likely to recommend laser just because it tends to be safer since you are only getting treated with a single wavelength of light, instead of multiple. Laser is easier to predict and control.

Ethnic or darker skin, even suntanned skin, is more
challenging to treat. Performing test spots (small areas of skin on which the
laser is tested) to determine how your skin will react to the laser is a good way
to ensure safety and efficacy with your light based treatment.
