What to expect with Photodynamic Therapy in NYC?

You should protect your skin with zinc oxide sunscreen of at least SPF 30 for a month prior to treatment, to minimize risk of discoloration. Stop using artificial tanners three weeks in advance. Then:

  • Skin is cleansed to remove all traces of makeup and oil
  • An aminolevulinic acid solution is applied
  • After 60 minutes, you don protective goggles while skin is treated with blue light for about 15 minutes. You feel warmth, tingling, or stinging for approximately 30-60. Since topical numbing is not effective for this treatment, we keep skin comfortable with a cooling device
  • Sunscreen is applied, and you may return home
  • Tingling, warmth, redness, and swelling may persist for up to three days. Discomfort can be managed with cool compresses and over the counter analgesics
  • Skin flakes for about a week. Cleanse it gently—no scrubbing—and keep the treated area covered with a thin layer of petroleum jelly
  • You may wear makeup when there is no longer redness or crusting
  • It is essential to avoid sun exposure for the first 48 hours, and continue to use sunscreen until healing is complete
