Pico Laser

PicoPlus, Picosure, PicoGenesis, Discovery Pico or PicoWay. Which Pico laser is the best in Malaysia?

… and not to forget PicoCare. No, Pico Focus is not a brand. Really.

You may be suffering from certain skin concerns whether it is pigmentations, scars, uneven skin tone or simply dull skin. You might have read about laser treatments for the skin, but there are so many different skin lasers out there, how do you know which one is the right one for you?

Aesthetic clinics as well as an infamous ‘laser centre’ (we all know that one. Pun intended) are aggressively marketing their pico laser treatments in your face.

Some irresponsible quarters even advertise their Pico Laser as a nonsurgical face lift treatment, which is completely absurd, considering that skin tightening requires heating up layers of the skin, which is the exact opposite of what pico lasers were created to do. Read on to find out more.

There is just so much hype surrounding the use of pico lasers, but how much do we actually know about the technology? In this article, I will peel away the layers of misleading marketing, and expose to you the technology and truth behind pico lasers.

What are pico lasers?

In the past, Q-Switched lasers were widely practised for removal of tattoos as well as treatment of acquired pigmentation disorders such as melasma, freckles, uneven pigmentation and dull skin.

The Q-Switched laser delivered pulses of high energy in nanosecond domain which is able to selectively target and destroy pigmentations so that your immune cells can eliminate it over time.

Compared to older CO2 lasers and Er:YAG lasers, Q-Switched Nd:YAG and Ruby lasers were relatively selective to pigmentations, and resulted in much lesser adverse affects and recovery time.

However, it was realised that Q-Switched lasers resulted in a steady state after a certain number of treatments, and further treatments did not improve the condition. Moreover, prolonged treatment would result in various unwanted side effects were noted such as mottled hypopigmentation (photo below) as well as postinflammatory hyperpigmentation.

Picosecond lasers were later introduced, which delivered pulses in the picosecond domain. For reference, a picosecond is a trillionth of a second. Which means 0.000,000,000,001 seconds. 

 

Why picosecond?

The shorter the pulse duration, the less bulk heating is generated. But is that necessarily a good thing?

Shorter pulse durations would result in what is called a photo acoustic effect. The rapid heating and expansion of pigments results in a photo acoustic wave which shatters the pigment particles into tiny particles for elimination by your immune cells.

Photoacoustic effect differs from photothermal effect, where longer pulses of energy result in accumulation of heat in the pigment.

A lot of the unwanted adverse affects from laser treatments result from excessive energy causing tissue heating. This in turn could either damage our melanocytes, causing hypo pigmentation (white spots) or overstimulates them, causing hyperpigmentation (dark spots). In worst case scenarios you get a combination of both, resulting in mottled pigmentation.

Therefore, the Picosecond lasers are meant to result in better pigmentation clearance while minimising the adverse affects.

How do i decide on the best pico laser?

Picosecond laser is simply a technology, and various companies are able produce this technology. However, there is still a difference in terms of the wavelength, the pulse duration as well as the energy consistency by these laser machines.

The best picosecond lasers would have undergone stringent quality control, especially the US FDA approval which is highly regarded worldwide. The US FDA would only approve devices medical devices which have a proven high safety and efficacy profile

PicoPlus treatment by Dr Bob Clinic

PicoPlus is the latest Picosecond laser by leading aesthetic device manufacturer Lutronics. It was US FDA approved in 2018, further establishing the safety and efficacy of the device. PicoPlus is also the 1st device approved by the Ministry of Food and Drug Safety (MFDS) for treating melasma.

 

How is PicoPlus different from PicoSure, Pico Genesis, Discovery Pico or PicoWay?

..and PicoCare. Almost forgot that one.

PicoPlus offers extremely short pulse duration at 450ps compared to other well known brands of pico laser such as PicoSure and Pico Genesis at 750ps. PicoWay and PicoCare also operates at 450ps, whereas Discovery Pico can operate at 370ps. As mentioned earlier in this article, shorter pulse duration equals better safety. 

Shorter pulse duration translates to better efficacy because the higher peak power achieved (laser pulse duration inversely related to peak power). PicoPlus and Discovery Pico generates the highest peak power (1.8GW) compared to Picosure (0.36GW), PicoWay (0.9GW) and even PicoCare (1.33GW) despite the latter two also having 450ps pulse duration. 

Another factor that sets PicoPlus apart is the capability of producing 4 different wavelengths (1064nm, 532nm, 595nm, 660nm) to effectively target almost every type of skin concern, whether it is tattoos and acquired pigmentary disorders, acne and erythema, or even skin rejuvenation for scars and wrinkles. 

PicoSure and Pico Genesis has only 2 wavelengths whereas Discovery Pico and PicoWay has only 3 wavelengths. The only other laser that can produce up to 4 wavelengths is PicoCare. Bear in mind having access to the extra wavelengths are only beneficial in the hands of trained professionals. 

This study Choi, M.S., Seo, H.S., Kim, J.G., Choe, S.J., Park, B.C., Kim, M.H. and Hong, S.P., 2018. Effects of picosecond laser on the multi-colored tattoo removal using Hartley guinea pig: A preliminary study. PloS one, 13(9), p.e0203370. showing the effectiveness of different wavelengths in the removal of different coloured tattoos would give us an idea why it is important to have access to multiple wavelengths.

Taking all these factors into consideration, Dr Bob Clinic has chosen to work with the PicoPlus due to having the upper hand of shorter pulse duration (450ps), highest peak power (1.8GW) and the ability to offer up to 4 different wavelengths.
