To get used to Philips Lumea, we recommend that you first make test flashes near the area you are intending to treat and continue with the highest setting that still feels comfortable and does not give side effects. Different body areas may have different sensitivity and skin color. So make sure you do the skin test on every area you wish to treat and choose the settings accordingly.
If the treatment feels uncomfortable, reduce the intensity. The treatment should not feel painfull at any time.
