Are IPL home devices (for hair removal) safe to use for areas w/ KP (keratosis pilaris)? Considering KP scars and discoloration

I have read that most home IPL device brands advice not to go over areas with moles and tattoos, because the device targets areas that have pigments that are darker than (or in contrast with) your skin color. How then does this work on areas with KP, especially those with hyperpigmentation and scarring from KP
