Is picosecond laser treatment safe in skin of colour?

Skin of colour contains more active pigment in many people, so inflammation or heat from a laser can sometimes be followed by darker or lighter patches. A picosecond device delivers very short pulses of energy, but the device name alone does not determine safety. The wavelength, energy level, spot size, treatment aim, and your skin’s response all matter.

The same treatment may be appropriate for one person and unsuitable for another. A clinician should identify whether the concern is pigment, a tattoo, a scar, or another condition before choosing settings. A history of dark marks after irritation, recent tanning, active infection, or medicines that increase light sensitivity should be discussed.

Choose a qualified clinician who regularly treats your skin tone and can explain the device and its settings. Follow instructions about sun exposure, skincare products, and shaving or waxing. Ask whether a small test area is appropriate before treating a larger region. After treatment, use the recommended gentle care and protect the area from sunlight; do not pick crusts or add irritating products without advice.

Contact the treating clinic if pain, swelling, blistering, oozing, or redness is increasing rather than settling. Arrange assessment for new dark or pale patches that persist, or for signs of infection such as worsening warmth and pus. Seek urgent help for facial swelling, breathing difficulty, or a widespread blistering reaction.

Ask what the laser is treating, why its wavelength and settings fit your skin, whether a test spot is useful, and how pigment changes will be managed. Clarify expected recovery, sun protection, and what to do if your skin becomes darker after treatment.
