What type of skin color is the 532 nm laser suitable for?

The 532 nm laser is particularly effective for lighter skin types, specifically types 1-3, which include very fair to moderately pigmented skin. This wavelength is highly absorbed by melanin, which is present in higher concentrations in darker skin types (4-6). As a result, the use of a 532 nm laser on darker skin may increase the risk of hyperpigmentation, hypopigmentation, or other adverse effects due to the higher melanin content that can absorb the laser energy, leading to potential skin damage.

Given this understanding, skin types 1-3 are the most suited for treatment with the 532 nm laser because they have less melanin, allowing for effective treatment while minimizing risks of complications.
