When to stop getting PDL for pink skin? (photo)

Pulsed dye laser remains the gold standard for PIE. I would combine the PDL with Limelight IPL to further enhance results. Best, Dr. KaramanoukianLos Angeles

a Yag or Ruby laser can also help improve post inflammatory erythema, but you can also use lightening creams or have a chemical peel. Please consult an expert cosmetic dermatologist to discuss the best and safest treatment options for your PIE. Best, Dr. Emer

Pulsed dye lasers are great for pink or red skin or PIE.
Efficacy from pulsed dye lasers is related to destruction of blood vessels with expected bruising and unfortunately, potential for hyperpigmentation, hence the need to use such products. Link is provided for more information.
V Beam is a pulsed dye laser. 
Pulsed dye laser can cause bruising and swelling and I precondition and treat my patients with a bioflavonoid product called Swell-x pt (post treatment) and also an oral supplement for PIH relief called Scler-X and I find them to be effective. 
For hyperpigmentation relief we use a HQ and non HQ based creams in  the U.S. called Melarase.

Always be guided by your specialist. Often with PIE or redness, spacing treatments 2-4 months apart can help. Base line photos will tell the story and improvement. Dr Davin Lim. Brisbane, Australia.
