Let our Pigment Eraser Laser Treatment wipe away what time and sun exposure have done to your skin. Pigment Eraser can be used to treat sun spots, age spots and even melasma. Within days of treatment, you'll notice a dramatic improvement in the appearance of your skin. Here's how it works: the laser gently breaks the pigment into tiny particles. The dark spots then turn darker before fading revealing a more even skin tone.
