Are there any contraindications for timing pulsed dye laser treatments too close to each other?

The Pulse Dye Laser requires 2-3 weeks of
healing and resorption of hemoglobin, heme, and other pigments from blood.
Also, capillaries need this time to contract and coagulate. We recommend a 4-6
week interval between treatments based on these well-established principles.

Hello.  The answer to the question is that it depends on the type of treatment (birthmark, Rosacea, scars, etc).  We usually space between 3-6 weeks apart.  One other dependent is whether the patient will have bruising or not.  Bruising takes longer to recover from.To see examples of before and after pictures of pulsed dye laser treatments in Los Angeles, click the website link below.  

The time required between each treatment depends on what is being treated.  When treating Rosacea, I usually recommend treatments be done 4 weeks apart.  If the patient has a treatment that causes bruising, 6-8 weeks is better.  Hope this helps!
