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

Pulsed Dye laser won't change the volume/fat content of face.  For rosacea pulsed dye laser or excel V is the best and focuses only on redness. See an expert.  Best, Dr. Emer.

Any of the pulse dye lasers can be used on redness and "broken capillaries" The Dye laser does not penetrate to the fat layer so cannot cause fat loss.  Hope this helps.  

V-Beam is the gold standard for treating redness or rosace and does not cause volume loss.  In fact, the V-Beam produces new collagen.  Please consult a specialist.  Best, Dr. Green
