My dermatologist suggested PDT using IPL instead of Blue light to get rid of sun damage in my face and chest. Will that make my sun spots go away? Will it improve my skin texture? What other benefits does the treatment have? I have broken capilarities and my skin is pretty rough and dry. Thank you so much!!!!
What Kind of Anti-aging Benefits Does PDT Have if IPL is Used Instead of Blue Light?

PDT Treatments with Sciton laser
The treatment uses a photo-sensitizing agent that is applied to the affected areas being treated which is then exposed to specific wavelengths of light to activate the drug as well as treating redness, broken capillaries and skin discolorations. The Sciton ( Broadband Light laser) is also highly effective in treating acne in the same manner.
IPL and levulan for pre-cancers, acne
We often use IPL (intense pulsed light) with levulan to treat pre-cancers on the face and for acne treatment. Typically, patients sit with the levulan for one hour. The IPL is then performed. It feels like a rubber band snap. The treatment "lights up" precancerous areas, which turn red and peel for 1-2 weeks. Using an IPL has the added benefit of treating broken capillaries and brown spots.
IPL can activate PDT similarly to Blue Light
Dear Gabb, Blue light is typically used for photodynamic therapy because the chemical used in PDT has the highest activation in that wavelength. However, an IPL can be used to activate the chemical also. It will have similar effects in that it will cause pre-cancers and superficial skin cancers that have taken the chemical up to "light up" - i.e. the abnormal skin cells die. IPL has separate effects on red spots and dark spots but that effect is different than activating the cream for PDT. Good luck, Dr. Mariwalla
