Pulsed light devices are not suitable for everyone. IPL technology works by identifying the pigment in the hair, called melanin, and destroys the hair follicle from the root, preventing new hair from growing. The light focuses on the melanin and the treatment is as effective as the lighter the skin and the darker the hair.
It is important to note that IPL is most effective on individuals with lighter skin tones and darker hair colors. This is because the light energy is primarily absorbed by the melanin pigment in the hair. In individual's skin that's rich in melanin, the excess melanin can also absorb the light energy, leading to potential skin damage.
Similarly, IPL may not be as effective on individuals with light hair colors such as blonde, gray, or red. This is because these hair colors have less melanin content, making it challenging for the IPL device to target the hair follicles effectively.
