Hyperpigmentation can sometimes signify a more serious underlying health condition such as Addison’s disease or hyperthyroidism. While hyperpigmentation can appear anywhere on the body, most forms of the condition usually develop on the face, neck, shoulders, and hands, areas that are most frequently exposed to the sun.
A variety of laser treatments, such as non-ablative resurfacing lasers (Fractional Lasers), Pigment-seeking lasers (Q-switched and Picosecond), and Ablative fractional lasers (CO2), have been shown to reduce hyperpigmentation. Most do so by targeting beams of light onto the affected area of the skin. With ablative lasers, this process rejuvenates the skin by resurfacing its upper layers, enabling new skin to form while simultaneously stimulating collagen development. Most laser treatments work in varying degrees to improve the appearance of lentigines and rhytids, eliminate photoaging, and treat post-inflammatory hyperpigmentation (PIH) by softening and depigmenting the scarring caused by acne.
