The Discovery Pico Laser (or picosecond laser) comes in an ablative and non-ablative mode. It is used for pigmentation removal, acne scars, skin rejuvenation and brightening, and tattoo removal.
The Pico Laser works in ultrashort picosecond laser pulses, as compared to nanosecond pulses. The pulse duration (how much time 1 laser shot stays on the skin) of a Picosecond Laser is 100x shorter. This means more shots can be fired by a Picosecond Laser in the same amount of time.
The shorter pulse duration also means that the skin heats up less. This reduces the risk of hyperpigmentation which can sometimes form due to laser procedures.
The Pico Laser mainly operates at a 1064nm wavelength. The Discovery Pico Laser, with its patented Quanta Pico-Boost Technology, can deliver up to 1.8GW of power, making the Discovery Pico a powerful laser.
The Picosecond laser breaks down pigmentation into much smaller fragments. This not only enables to skin to clear these fragments faster and easier, it also reduces the number of treatments required.
With the Discovery Pico Laser, pigmentations and tattoos can also be cleared much faster (i.e. fewer sessions).
At 1064nm wavelength, the Pico Laser targets pigmentation. Pigmentation under the skin absorbs the laser energy shatters into smaller fragments. These fragmented pigments are then removed by the skin’s immune system.
For patients seeking treatment for active acne, the Q-Switched Laser (or Pro Yellow Laser) will still be the laser of choice. This is due to the higher amount of heat generated which kills P.acne bacteria, reduces inflammation, and shrinks oil glands.

You can return to work or daily activities immediately after the laser. You should avoid prolonged / intentional sun exposure for a week post-laser to avoid hyperpigmentation. Creams are sometimes prescribed for this purpose as well.
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.
Depending on condition and the type of pigmentation, number of treatments can vary. A few factors influence the outcome of the treatment; nature of pigmentation, skin type, skin health, hormones, sun exposure, acne, etc.
On average, about 4 – 6 treatments will be required for best results.
Most pigmentation, like tattoos, will not return after removal. However, due to sun exposure, ageing and hormonal changes (mostly in women), new pigmentation can develop.
It is important to apply sunscreen to prevent new pigmentation from forming. Regular maintenance treatments with the Pico Laser or Q-Switched Laser can also benefit some patients.
