Can Pulse Dye Laser (PDL) make red marks disappear? How many times will it take to make the red marks go away?

Yes, PDL removes red spots,
scars, and other dermatosis. One to three treatments will suffice for 90% of
conditions and treatments should be done four to six weeks apart. The face is
pink to purple for five days following a pulse dye laser treatment.

PDL may work depending on the cause of the redness. For angioma and stretch marks it may take 1-2 treatments, which can definitely improve redness.

The pulsed dye laser was designed for red spots and is perfect for this treatment.  It may take 3 to 6 treatments of the V-Beam (pulsed dye laser) to remove these spots.  The treatments should be scheduled one month apart for the best cosmetic results.  

The PDL or pulse dye laser, most commonly referred to as the V Beam is ideal for red spots. As to your question as to how many times will it take, it really depends on the spots you are treating. I will give you a few examples-1. Spider naevi - one treatment2. Fixed rosacea- 3-4 treatments3. Birthmarks - anywhere up to 10 treatments4. Acne ' red scars' (Macular erythema)- up to 4 treatments. A Dermatologist can first give you a diagnosis, then suggest the treatment of choice. CheersDr Davin Lim Laser and Cosmetic DermatologistBrisbane, AUSTRALIA
