I have some sun damage, hyperpigmentation, on my face -- Did a series of 3 IPL treatements,
Saw some results after the first treatment (dark patches surfacing like "coffee granules" and washing away over about a week), but never saw any results after first treatment. In fact, I believe the hyperpigmentation is worse now. Of course they suggested another series of 3. HA! Fool me once...
BTW - not painful at all. Mostly felt nothing, in some areas on my face, felt like someone snapping a rubber band very lightly on my face.
Have had much better results with hydroquinone. Although you can never stop, or you quit getting results.
