Diode laser hair removal employs semiconductor technology that produces a coherent projection of light in the visible to infrared range. It is very effective for darker skin types and is designed to target the melanin in the hair follicle without excessive damage to the surrounding skin. Diode lasers are particularly effective for reducing hair on the legs, arms, and back with fewer sessions needed compared to other laser types, making them a preferred choice for fast and effective long-term hair reduction.
