Both IPL and LED photofacials involve light being absorbed into the skin. The more intense nature of the IPL photofacial’s light pulses allows this light to be absorbed more deeply.
IPL photofacial light is soaked up by the hemoglobin (red blood cells) and melanin (pigmentation) in the skin, intentionally damaging these areas. The damaged melanin breaks up and is absorbed by the skin, decreasing its appearance on the skin’s surface. The damaged hemoglobin stimulates blood flow, causing the melanin to be absorbed more efficiently.
