Why is Pico Laser Better than Q Switch Lasers?

In the non-invasive cosmetic treatments industry, there are 2 kinds of laser treatments that are sought by many:  Pico lasers and Q-switch lasers. But which is more effective and which one suits you better?

Pico laser in Singapore is a laser that produces extremely short light pulses (picoseconds). A picosecond is a time unit equal to 0.0000000001 seconds. Because laser light pulses are so short, they effectively break tattoo pigment into tiny particles. This frees up the body to take care of the rest.

Before Pico lasers, a Q switch nanosecond laser was the top standard for tattoo and pigmentation removal. How the light is held back then discharged, allowing it to be extremely strong, is referred to as Q flipping. Consider the force of the water pouring down a river. But, if you temporarily keep the water in a dam and release it, it becomes much more powerful. A Q switch laser essentially does the same thing.

Nanosecond pulses are used in the majority of these lasers. Not a trillionth of a second, but one billionth of a second. When compared to a ‘Pico’ laser, however, the speed difference is minimal. That’s due to, although ‘Pico’ lasers utilize the word ‘Picosecond,’ they do not produce Picosecond pulses – they’re much slower!

Q-Switched Lasers Vs. Pico Lasers

Tattoo removal with Q-switched lasers, which have been available for numerous years, maintains to be the top standard. Because they radiate light in a split second, Q-switched lasers are ultra-short-pulsed lasers. The wavelength of light emitted by a Q-switched nanosecond laser is approximately 0.000000005 seconds. A picosecond laser lets out light for a fraction of the time it takes a nanosecond laser to radiate light. The shift in light physics significantly impacts what the laser could do in industrial and medicinal applications.

Short-Pulsed Lasers Are Effective In Natural Pigmentation

Lasers with short-pulsed durations, such as those in the microsecond (0.000001sec) or millisecond (0.001sec) range, are excellent for eliminating natural body pigmented abrasions like age spots. The heat of treatment is primarily restricted inside the pigment particles, causing small collateral skin injuries.

Q-Switched Lasers & Pico Lasers For Tattoo Removal

Tattoo ink particles may be shattered by both picosecond and nanosecond lasers. These devices reduce the heat from the procedure diffusing to the skin around due to the ultra-short pulses. As a result, therapeutic side effects are decreased.

Is Pico Laser Better Than Q-Switched?

Since nanosecond lasers stay curbed in restricting thermal damage within smaller targets, picosecond lasers were created (photothermal vs photomechanical). Furthermore, in regards to dissolving finer tattoo ink, the picosecond laser may provide higher shattering energy (peak power).

Advantage Of Pico Lasers

Now, what does all of this mean? Here’s the lowdown on picosecond lasers’ benefits:

Faster tattoo removal – There is sufficient evidence to promote tattoo removal in fewer sessions.

Non-specific targets – A certain wavelength in Picosecond lasers could eliminate more pigments than nanosecond lasers. A picosecond laser that targets a specific color, on the other hand, is still preferable for tattoo removal.

Less tissue damage – The capacity to deliver a brief pulse reduces heat transfer for the target pigments, resulting in less tissue damage. As a consequence, there’s less disturbance of surface tissue and more targeted therapy.

What Can Picosecond Lasers Treat?

Several of these disorders are not amenable to nanosecond laser therapy, but picosecond lasers have been used extensively in acne scar treatment, birthmark removal, and scar erasure.


Compared to the nanosecond laser, Pico laser in Singapore possesses a number of benefits when it comes to non-surgical skin rejuvenation. The nanosecond, on the other hand, is still highly successful in the procedure of most pigmented lasers, and it isn’t necessarily secondary to the picosecond laser in a lot of aspects.
