What are Pico Second Lasers?

Pico laser is a broad term that refers to laser systems that deliver ultra-short pulses of energy in picoseconds (a trillionth of a second). Laser systems differ in their specific features and capabilities.

Developed by Cynosure, Boston Massachusetts, USA, PicoSecond is an FDA-approved Alexandrite PicoSecond laser with a wavelength of 755nm. A variety of skin concerns can be treated, including pigmentation, tattoo removal, postinflammatory hyperpigmentation, acne scars, sun damage, dull skin, and open pores. A PicoSecond treatment can effectively and safely remove blemishes and revitalise the skin.

An Introduction to PicoSecond Laser

How Does PicoSecond Work?

The PicoSecond laser emits a focused laser beam for a trillionth of a second. Due to the shorter pulse duration, the laser energy is highly concentrated, resulting in a photomechanical effect that converts laser energy directly into mechanical energy upon contact. Melanin or tattoo pigment in the skin is thus shattered into dust-size fragments and cleared by the lymphatic system. As part of a PicoSecond laser treatment, a diffractive lens called the Focus Lens Array concentrates laser energy to produce Laser Induced Optical Breakdown (LIOB) in the skin, a controlled injury that spares the epidermis and stimulates wound healing that results in collagen and elastin production, thus rejuvenating the skin.

Why PicoSecond?

Unlike traditional Q Switched nanosecond lasers, PicoSecond emits a laser beam for picoseconds (a trillionth of a second), whereas traditional nanosecond lasers emit a laser beam for nanoseconds (billionths of a second). As a result of the fast pulse duration, laser energy can be converted directly into mechanical energy (“photomechanical effect”) rather than thermal energy (“photothermal effect”). In layman’s terms, it means better results and a lower risk of laser complications like burns or post-inflammatory hyperpigmentation.

AURA exclusively uses the 755nm wavelength with its PicoSecond laser, unlike other picosecond lasers that operate at the 1064nm wavelength. For pigmentation treatments, the wavelength of 755 nm is ideal because it absorbs melanin 50 times better than blood (melanin:blood absorption coefficient) than the wavelength of 1064 nm, which absorbs melanin 16 times better. A 755nm wavelength can target melanin more precisely in pigmentation, while sparing surrounding blood vessels. In short, better results with less redness and pinpoint bleeding.

PicoSecond is the FIRST laser technology to receive FDA approval in 2012, and it has been clinically validated, with 26 publications and 59 abstracts. With over 10 years of industry experience and a reputation for effective treatment, it is the picosecond laser of choice.

It is also the first and only aesthetic picosecond laser that is FDA-cleared for the removal of tattoos.

Absorption Ratio Of Melanin To Blood
755 has 3x the absorption ratio of melanin to blood (vs 1064)

755 Safety and Efficacy Advantages:

  • Reduce risk of pinpoint bleeding
  • Minimizes side effects
  • Uniquely revitalizes skin with virtually no downtime

What is the difference with PicoSecond and other Pico Lasers?

PicoSecond is a specific brand of laser technology. Pico laser is a broader term that refers to laser systems that deliver ultra-short pulses of energy in picoseconds (a trillionth of a second). The main difference between laser systems is their specific features and capabilities.

Being one of the pioneers of laser technology, PicoSecond uses a single wavelength (755 nm) and a single laser medium (Alexandrite). Laser-induced optical breakdowns (LIOBs) can be generated by PicoSecond’s patented focus lens array, promoting collagen deposition and rejuvenation. With this treatment, tattoos, pigmented lesions, acne scars, and other skin concerns can be precisely and effectively addressed.

There are other brands of Pico lasers that operate in the picosecond range, but use different wavelengths, usually 1064nm and a Neodymium Yag laser medium (“NdYag”).

The PicoSecond 755nm wavelength has three times as much affinity for melanin as the 1064nm wavelength, meaning it targets pigmentation more effectively with minimal damage to the skin’s blood vessels. A PicoSecond laser treatment leaves no bleeding or minimal redness.

Clients can go back to almost their usual activity almost right away without the telltale pinpoint bleeding marks known as petechie that are commonly seen after 1064nm PicoLaser treatments. Furthermore, PicoSecond’s 755nm wavelength allows for more rapid results and fewer treatment sessions. PicoSecond is typically more expensive per treatment than other PicoLasers, but the overall cost is often lower because fewer treatments are needed.

Frequently Asked Questions

What is the average treatment time?

Topical anaesthesia is applied 15-20 minutes before the laser treatment, which takes 10-15 minutes.

Any pain?

While each person’s pain tolerance is different, it can generally be said that there is little to no discomfort encountered with PicoSecond treatment. Seriously.

Is there any downtime?

There is no downtime, for all intents and purposes. Truly.

How to take care of the skin after a treatment?

Avoid the sun, use copious amounts of sunblock, drink lots of water. Do not rub or scratch your face.

What can I expect after treatment?

There may be slight redness for 1 – 3 hours after treatment. It is common for the treated areas to turn darker after a treatment. The spots will fade off in 2 weeks’ time if not sooner.

When can I expect to see an improvement in my complexion?

Generally within 6 – 8 weeks, your complexion will gradually become clearer and brighter.
