IPL treatment primarily targets melanin in the hair for effective results, which means that very light blonde, red, or grey hair may not respond well to IPL. The suitability of IPL also varies based on skin tones. For the Valossi Laser Hair Removal it is most effective for individuals with fair to warm tan skin tones. If you fall within the warm tan category, we recommend beginning at Intensity level 1 and conducting a patch test before your treatment. Regardless of your skin type, we recommend starting at Intensity level 1 and always performing a patch test when changing intensity levels. Your safety and comfort are our priorities.
