**Введение:**
PicoSure and Q-switch lasers both target pigmentation, but they differ in pulse duration, tissue interaction, and clinical strategy. Device choice should match diagnosis, skin type, and safety profile.
**H2: Core Difference**
Q-switch systems operate in nanoseconds and rely mainly on photothermal impact. Picosecond systems such as PicoSure emphasize photomechanical/photoacoustic disruption with lower thermal diffusion.
**H2: Clinical Indications**
Both may be used for selected pigmentation and tattoo indications, while protocol details differ by lesion depth, recurrence risk, and Fitzpatrick type.
**H2: Safety by Skin Type**
For darker skin types common in Dubai, conservative parameters, correct wavelength selection, and physician expertise are critical to minimize PIH risk.
**H2: Practical Expectations**
Pigmentation improvement is gradual and often requires multiple sessions, particularly for melasma and mixed-depth pigment. Combination management (topicals + strict photoprotection) is often necessary.
**Заключение:**
The most important variable is not just the device but the treatment plan and operator expertise. Evidence-based protocol selection improves safety and outcomes.
