Pico Laser

What is a Pico Laser?

The pico laser (or picosecond laser) operates in both ablative and non-ablative modes. It is used for pigmentation removal, acne scars, skin rejuvenation and brightening, and tattoo removal.

The pico laser delivers ultrashort picosecond pulses, compared to the longer nanosecond pulses. The pulse duration (how much time one laser shot stays on the skin) of a picosecond laser is 100 times shorter, allowing more shots to be delivered in the same amount of time.

The shorter pulse duration means the skin heats up less, which may reduce the risk of hyperpigmentation sometimes associated with laser procedures.

How the Pico Laser works

The pico laser primarily operates at a 1064nm wavelength. Using a patented Quanta Pico-Boost Technology, Mizu’s choice of pico laser can deliver up to 1.8GW of power.

The picosecond laser breaks down pigmentation into smaller fragments, which may help the skin clear these fragments more efficiently and potentially reduce the number of treatments required.

The pico laser can clear pigmentation and tattoos in fewer sessions.

At a 1064nm wavelength, the laser targets pigmentation. The laser energy is absorbed by the pigmentation, breaking it into smaller fragments. These fragmented pigments are then removed by the skin’s immune system.

dr YZ Tan

recommends addressing pigmentation conditions with a few sessions of the pico laser and maintaining results with regular sessions of the Q-switched laser.

For patients seeking treatment for active acne, the Q-switched laser (or yellow laser) is preferred due to the heat generated, which targets P. acne bacteria, reduces inflammation, and affects oil glands.

frequently asked questions

The level of discomfort experienced during the procedure can vary depending on an individual’s pain tolerance and the location of the pigmented lesion(s). Most patients tolerate the laser sessions well with minimal discomfort. The laser may feel like tiny warm pricks on the skin.

Some patients may experience a pinkish flush or mild itchiness after the laser treatment. These side effects typically resolve within a few hours.

You can return to work or daily activities immediately after the laser treatment. It is advisable to avoid prolonged or intentional sun exposure for a week post-laser to reduce the risk of hyperpigmentation. Creams may be prescribed for this purpose.

For some patients, greying, browning, or darkening of existing pigmentation may occur before it fades. This is normal and typically resolves over time.

For certain patients, greying/browning/darkening of the existing pigmentation may be expected before it fades off. This is normal and not a cause for concern as it fades off with time.

The number of treatments needed can vary depending on the condition and type of pigmentation. Several factors influence the outcome of the treatment, including the nature of the pigmentation, skin type, skin health, hormones, sun exposure, and acne.

On average, about 4 to 6 treatments may be needed for optimal results.

Most pigmentation, like tattoos, will not return after removal. However, new pigmentation can develop due to sun exposure, ageing, and hormonal changes (mostly in women).

It is important to apply sunscreen to help prevent new pigmentation from forming. Regular maintenance treatments with the pico or Q-switched laser may also benefit some patients.
