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.

No matter what, multiple treatments of IPL are needed. You should not have an expectation that all brown spots will be clearing up with a single IPL treatment. Additionally, often I see people who have had dozens of IPL to treat brown spots and they aren't even the types of spots that can be removed with an IPL! It's very important that a physician (dermatologist preferably) is involved in your care, to lay out what to expect, and treat the things that aren't able to be treated with IPL. A lot of the brown spots I see on your photo, aren't going to clear up with IPL, period. It's not possible. Second, the burn is very bad and frankly, shouldn't have occurred. Based on it, I would recommend you consider seeing a different office!
