Can the pulsed dye laser treatments cause loss of underlying facial fat?

The 595 nm of pulse dye laser is very superficial, in fact it only penetrates to the upper layers of the dermis. For larger deeper vessels we use a long wavelength laser. Pulse dye laser does not cause fat loss because the level of penetration is weak, and the amount of heat delivered is very short. Rest assured it will not dissolve filler, nor will it cause fat loss.
