LASERS FOR PIGMENTATION

Picosecond and Q-Switched lasers are specialist medical lasers that deliver very short bursts of energy to target pigment within the skin. They are widely used in dermatology for the management of pigmentation disorders and for the safe removal of tattoos.

As a Consultant Dermatologist in London, Dr Kentley is trained in the use of advanced laser technologies and can advise whether a picosecond or Q-Switched laser is suitable for your skin concern. For pigmented lesions, it is important to have these evaluated by a dermatologist prior to considering laser to ensure that a potential skin cancer is treated incorrectly.

What Can These Lasers Help With?

Pigmentation Disorders

  • Sun spots / age spots

  • Freckles

  • Post-inflammatory pigmentation (after acne or injury)

  • Certain birthmarks (e.g. café-au-lait macules)

  • Selected other pigmentary conditions

Tattoo Removal

  • Black and dark ink tattoos (typically respond best)

  • Coloured tattoos: picosecond lasers may be more effective at targeting stubborn colours such as blue and green

How the Lasers Work

  • Q-Switched lasers deliver nanosecond pulses of high energy that break down pigment into smaller particles, which the body’s immune system gradually clears.

  • Picosecond lasers emit pulses that are even shorter in duration, allowing finer targeting of pigment with potentially fewer sessions.

  • Both types of laser can be adjusted depending on the colour, depth, and type of pigmentation or tattoo being treated.

What to Expect During Treatment

  • A consultation is essential to confirm suitability and set realistic expectations.

  • Protective eyewear is worn during the procedure.

  • Patients often describe the sensation as a quick snapping or stinging feeling.

  • Sessions usually last 15–45 minutes, depending on the treatment area.

  • Multiple treatments are usually required, spaced several weeks apart.

Aftercare and Recovery

  • The treated area may appear red, swollen, or blistered for a few days.

  • A protective ointment and dressing may be applied to support healing.

  • Patients should avoid sun exposure and use broad-spectrum sunscreen on treated areas.
