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