Break Out of the Mold with PicoSure Honeycomb and PicoWay Holographic Focus Picosecond Lasers
The medical team at L’Excellence uses U.S.-made PicoSure and PicoWay picosecond lasers, which are both certified by the USFDA and Taiwan MOHW and cover the complete spectrum with 532nm, 755nm, and 1064nm wavelengths. The holographic focus technology of PicoWay and the honeycomb focusing array lens of PicoSure both use high-speed, high-energy lasers to create a focal point on the skin where they stimulate the production of collagen, flatten any acne scars or wrinkles, and reduce the appearance of large pores, spots, and dull skin for a refined and radiant look.

PicoSure Honeycomb Focus Array Lens Laser
- 中文名稱： 色若修皮秒亞歷山大雷射及配件
- 英文名稱：Cynosure PicoSure Alexandrite Laser and Accessories
- FDA Licensing No. 025317
PicoSure accurately breaks apart the melanin in the skin with energy levels sufficient for destroying melanocytes without unnecessary repeated exposures that can cause heat damage to the skin tissues. This helps to greatly reduce the temporary darkening that is the skin’s response to treatment.

How It Works
The PicoSure laser uses a single 755 nm wavelength, while the PicoWay laser uses dual 1064 nm and 532 nm wavelengths.
The PicoSure 755 nm laser uses a honeycomb focus array lens. It is commonly known on the market as the honeycomb picosecond. The extremely short pulses work on the picosecond scale (10-12 sec) to create the so-called photomechanical effect. Compared to the thermal effects of traditional nanosecond (10-9 sec) lasers, picosecond lasers avoid the post-treatment skin darkening that results from residual heat while working to directly break apart their targets. The result is blemish-free, smooth skin with fewer treatments.
The holographic focusing technology of the PicoWay laser combines a holographic diffuser with dual-layer focusing. It uses diffraction to first split the laser beam then refocus it to deliver treatment at 22 times the power. Without damaging the skin, it forms what’s known as the “laser-induced optical breakdown effect”. This effect acts like invisible fractional lasers working on two layers deep in the skin without the recovery time or pain associated with the heat of fractional lasers. The 1064 nm wavelength can penetrate into the dermis, while the 532 nm wavelength focuses on the surface of the skin for effective treatment at two depths via the high-speed picosecond waves of the 360 degree holographic diffuser. This is effective for invigorating collagen and elastin as if a 3D lattice of fillers was set up within the skin for all-around healing and protection resulting in healthy, plump, firm skin.
Before treatment, pigments in the underlayer of the skin appear like the colored granules pictured above.
Nanosecond therapy and the photothermal and partial photomechanical effects break up the granules into smaller particles.
Picosecond therapy and the high-speed photomechanical effect break up the granules into microparticles which are then metabolized by the body.
What Is a Picosecond?
A picosecond (ps) is a unit of time. Before the advent of the picosecond, laser therapy machines typically operated on the nanosecond scale (10-9 sec). With the advancement of technology, there came the development of lasers that operate on a scale 1,000 times faster than the nanosecond: the picosecond (10-12 sec). The rays from the PicoSure 755’s 550 ps laser release all their energy within 550 x 10-12 sec to atomize the melanin in the skin. This not only reduces heat damage and shortens recovery time, it also lowers the incidence of post treatment skin darkening while allowing the melanin to be rapidly metabolized and expelled from the body.

After treatment with a traditional laser, the melanin becomes granulated.
After treatment with 755 a picosecond laser, the melanin becomes atomized.
From the images comparing the effect of different lasers on melanin, you can see that after treatment with a PicoSure 755 picosecond laser, the melanin is broken down more finely. Once the picosecond pulses atomize the melanin, it is then more easily engulfed by the body’s immune cells. This greatly reduces the incidence of inflammation and side effects such as reddening and darkening of the skin.

The Shorter the Pulse, the Greater the Photomechanical Effect
Micro pulses are used for both their depth and area of treatment. Time is the secret to the success of picosecond lasers. The shorter the time, the less heat is produced and conversely the more powerful the energy is. During treatment, short pulses are used to instantaneously raise the energy levels high enough for the photomechanical effect necessary for therapy. Not only is this effective for eliminating pigment and spots in the skin, but it also avoids unnecessary heating and reduces treatment recovery time compared to traditional lasers.
Wavelength Selection
Standard mode: cleanses skin, removes spots and tattoos.
Holographic focus mode: invisible fractional lasers, eliminates wrinkles, reduces the appearance of scars, and improves overall skin condition.
In Taiwan, there are currently several types of dual picosecond devices for treating dark spots and removing tattoos. The fact that the PicoSure picosecond laser was the first to be used in Taiwan, coupled with its U.S. FDA approval, has earned it the reputation of being the “lord” of picosecond devices. It is well recommended by physicians and patients alike. One of L’Excellence’s dermatology specialists will assess the patient’s needs and provide customized treatment of dark to light skin spots to help improve any issues of the skin. We hope to provide our clients with comprehensive picosecond laser services.

Frequently Asked Questions
- An assessment will be done by a professional dermatologist to determine the health of the skin and any problem areas as well as suitable treatment devices and energy levels.
- Treatment is not recommended for pregnant women or those with blood or immune disorders.
- Those taking medication that causes photosensitivity or using products containing retinoids are advised to discontinue use and to seek advice from a specialist on whether or not treatment is recommended.
- Please refrain from undergoing acid or laser therapies within one month prior to treatment.
- Please refrain from exfoliating or over-exposing the skin to UV light within one week prior to treatment.
