Which skin type may require more caution when undergoing laser treatment?

Type IV skin, which typically refers to Mediterranean skin tones that tan easily but can also burn, requires more caution during laser treatments due to the increased risk of hyperpigmentation or other adverse effects. The melanin content in Type IV skin is higher than in lighter skin types, which means that the laser’s energy can be absorbed more readily. This can lead to complications such as post-inflammatory hyperpigmentation, especially if the treatment settings are not adjusted appropriately.

In contrast, Type I skin is very light and prone to burning, thus usually requiring different considerations regarding treatment settings but can be less prone to hyperpigmentation. Type II skin is light and might burn but is less of a concern than Type IV. Type III skin has a moderate tan and is also typically less reactive than Type IV. Therefore, practitioners must exercise extra caution with Type IV skin to ensure patient safety and optimal treatment outcomes.
