In the extensive amount of (clinical) research carried out into the Lumea, no women rated the experience as painful, providing that correct settings, according to skin tone and hair colour, were used.
In the tests, some women did describe 'a warm sensation', 'prickling' or 'itching' which in most cases disappeared within a few minutes up to one hour.
Test your Skin
To get accustomed to Philips Lumea, we recommended that you make test flashes near the area you are intending to treat, using the lowest recommended light setting. Once you are comfortable with this, you can increase the light setting, step-by-step if necessary, but it should never become painful.
