How does absorption of laser energy differ in various skin types?

The absorption of laser energy significantly differs across various skin types, and this variability impacts both the efficacy of the treatment and the potential for side effects. Different skin types have varying amounts of melanin, which absorbs laser energy at different rates. Darker skin types tend to have more melanin, which can increase the risk of side effects such as hyperpigmentation or burns when a laser is used. Hence, practitioners must adjust treatment parameters, such as energy settings and time, based on the specific skin type to ensure safe and effective treatment.

The other options do not accurately represent how absorption varies across skin types. Changes in treatment time can indeed affect absorption, which means it cannot be deemed unaffected. While the laser's power settings are a factor, they are not the sole influence, as skin type and other parameters also play a crucial role. Relying solely on patient feedback may not provide enough data to optimize laser energy absorption because objective measures and characteristics of skin type need to be considered for the best outcomes.
