Our Lumea models, SC1981-SC1985 and SC1996, SC1997 and SC1999 have a skin tone/color sensor. This skin color sensor ensures that a pulse will be emitted only on suitable skin colors.
Philips Lumea is suitable for most women, except those with naturally dark skin and women whose body hair color is gray, red, light blond or white. Make sure you've selected the recommended intensity suitable for your hair and skin color, and try lowering your current setting. Treat only shaved areas that are recommended in the user manual.
