Which laser treatment is best for removing pigmentation spots?

Laser pigmentation removal works by directing high-energy laser beams onto pigment particles in the skin, causing them to break down and be absorbed or expelled by the body, thus achieving the effect of removing pigmented spots. Different laser technologies target different types and depths of pigmentation. Commonly used lasers include picosecond lasers, Q-switched lasers, and IPL (Intense Pulsed Light) photorejuvenation.

Picosecond lasers are suitable for various types of pigmented lesions, including melasma, freckles, tattoos, etc. Using ultra-short pulse widths, they rapidly break up melanin, reducing inflammatory reactions. After treatment, it is essential to strictly follow medical instructions for skin care and avoid sun exposure to promote recovery. The effects of picosecond pigmentation removal typically last 1–2 years. Q-switched lasers are suitable for treating epidermal and dermal pigmentation, such as freckles and café-au-lait spots. High-energy pulses directly target pigment particles, breaking them down and expelling them from the body. Q-switched lasers are also highly effective for age spots or densely clustered spots. However, because Q-switched lasers may cause skin peeling, the recovery period is relatively longer. IPL photorejuvenation is more suitable for mild pigmentation.

When choosing a laser pigmentation removal technique, one should consider the type and depth of the pigmentation as well as individual skin characteristics. It is advisable to first visit a reputable medical facility for a skin examination and have a professional dermatologist evaluate your condition before selecting the most suitable laser treatment plan. Additionally, sun protection after laser treatment is important to prevent recurrence of pigmentation.
