Intense Pulsed Light (IPL) therapy, also known as a photofacial, uses light energy to treat skin conditions without surgery. The treatment works by delivering high-intensity pulses of broadband light into the dermis, the deeper layer of skin, while leaving the epidermis, the surface layer, untouched. The light is absorbed by the skin's melanin and hemoglobin, which are damaged in the process. The damaged melanin breaks up and is absorbed by the skin, while the damaged hemoglobin increases blood flow, which helps the skin absorb the melanin more efficiently. The body then gets rid of the unwanted cells, which can help treat a range of skin conditions, including sun damage, dark spots, age spots, and rosacea.
