It is very important to use the correct settings on your Philips Lumea, suitable for your skin tone. Always check the skin tone/hair color table in the user manual.
Some Philips Lumea models (BRI862, BRI863, BRI864, BRI94, BRI95 series) are equipped with a SmartSkin Sensor. The sensor recommends the setting which was comfortable for most women with a skin tone similar to yours. If the treatment feels uncomfortable with these settings you can always lower them manually.
