Understanding the differences between 532nm and 1064nm pico laser wavelengths is essential for choosing the right treatment. The 532nm wavelength targets superficial pigmentation and light-colored tattoos, making it ideal for lighter skin tones. In contrast, 1064nm penetrates deeper, safely treating dark tattoos and deeper dermal pigmentation across all skin types. Combining both wavelengths allows practitioners to address complex skin concerns more effectively while minimizing risk. Personalized wavelength selection guided by skin type and pigmentation depth ensures optimal results and long-term safety.
