Can IPL Cause Fat Loss if Used Undereyes?

IPL is commonly used for pigment and vascular problems of the skin. IPL (intense pulsed light) does not penetrate beneath the dermis of the skin and, therefore, should have no effect on the underlying fatty tissue. In contrast, there are other devices on the market which you may have read about that can cause fat contour changes following treatment, which include; radio-frequency devices like Thermage and focused ultrasound treatments like, Ultherapy, where the contour change through fat reduction is the goal of the treatment.  It is possible that the reviews on the internet you are seeing may be referring to some of these other technologies and not to IPL.  There is no cause for concern about IPL causing fatty tissue loss.

Sciton Broad Band Light (BBL™) provides patients
with a state-of-the-art laser system, which is able to treat multiple aesthetic
concerns, while being safe, non-invasive with no downtime. Patients benefit
from effective results and quicker recovery time than other more intensive
laser treatments.It is unlikely that any IPL treatments can safely target fat or indiscriminately cause fat atrophy causing hollowness under the eyes.#BBLundereyes   #BBLsideeffects   #BBLfatloss

Sciton® BBL technology treats sun-damaged and
aging skin effectively. The light energy delivered by the BBL will gently be
absorbed by the unwanted melanin responsible for pigmented lesions in the upper
layers of the skin.  It is highly unlikely that fat loss will occur with IPL/ BBL treatments as this is not the target the depth with the amount of energy necessary to destroy fat.#lowriskBBL  #fatdestruction   #BBLtreatments

I agree with others who responded.  Despite what you may have read, I do not think there is an association with IPL and fat atrophy.

Intense pulsed light (IPL) is a superficial treatment useful for treating pigment variations and small blood vessels. Although filters can be used to alter the wavelength, and thus depth of penetration, none go beyond the dermis into the deeper tissues where fat is found. 

IPL works for pigmentary issues and some use it for hair removal.  It is superficial and will not affect your Restylane or your own fat under your skin.

IPL does not come anywhere near the fat layers and will not injure the fat. Your internet reviews are made by ill informed people apparently. IPL does not even pass through all the layers of the skin and the fat is definately below the skin.

IPL is a superficial, mostly colored light source that affects superficial vessels and pigment.  IPL does not change the deeper fat.
