Shorter pulse widths are recommended for which skin type?

Shorter pulse widths are particularly recommended for skin types characterized by finer hair and lighter skin tones. This is because shorter pulse durations deliver energy more quickly, reducing the risk of overheating surrounding tissues, which is crucial when working with lighter skin types that are more delicate. The rapid delivery of energy targets the melanin in the hair follicles effectively while minimizing thermal damage to the skin. Additionally, lighter skin types typically have a lower melanin concentration in the skin itself compared to darker skin, allowing for safer and more efficient energy absorption by the hair follicles.

In contrast, longer pulse widths may be more suitable for darker skin types, where there is a higher melanin concentration in the skin. Using shorter pulse widths on these skin types can lead to complications, as the higher melanin levels can absorb more energy, increasing the risk of burns or hyperpigmentation. Thus, for optimal safety and efficacy, shorter pulse widths are primarily associated with skin types that allow for precise targeting of hair follicles without compromising the integrity of the surrounding skin.
