IPL After Four Days; How Long Before Brown Spots Go? (photo)

It may take several more treatments of intense pulse light laser for the browns spots to clear up or lighten up.  Do not expect that one single treatment will be enough.  Once you have had treatment, it may take 1-2 weeks for the dark spots to fade or flake off.

Typically 3-6 treatments and sometimes more are needed.  Burns shouldn't occur where blistering occurs in my experience.  The pigment working its way out can take a week or more sometimes.  It is critical that you be closely monitored to avoid scarring as topical steroids may be needed.  Best regards.

Brown spots or lentigines will fade over several treatments, most people requiring 4-6, but everyone is different. After your treatment, it can take 5-10 days for the flat brown spots to fade or peel off; do not pick at them, they'll come off when they're good and ready.
