PicoSure Laser: The Science Behind Beautiful Skin

by Andy Cheng Director

Not too long ago, Q-switched Nd: YAG Spectra laser was the gold standard for treating a wide variety of skin conditions such as pigments, melasma, and acne. The Q-switched laser was also effective for minimizing pores and removing tattoo.

Although results were good, the consensus is that the treatments were often painful and downtime was long.

How does Spectra Q-switched laser work?

Spectra laser works by exfoliating the epidermis i.e. outermost layer of the skin and stimulating the collagen production associated with skin rejuvenation. The wavelengths target both superficial and deep pigmentation.

Spectra Q-switched lasers traditionally rely on photothermal energy, delivering heat to the pigments and surrounding tissue.

Introducing Pico technology

Pico Laser Singapore is the talk of the town, promising its ability to achieve even better results than Q-switched lasers in all aspects.

Pico Laser is a non-ablative laser that is mainly used for tattoo removal, pigmentation removal, acne scar treatment, and overall skin rejuvenation and brightening.

It is a new generation laser that delivers ultrashort laser pulses in picoseconds, unlike traditional Q-switched lasers that deliver laser pulses in nanoseconds. In effect, this means that the laser pulses from Pico Lasers remain on the skin 100 times shorter than Q-switched lasers. In the same treatment time, more laser shots can also be delivered into the dermis.

The PicoSure difference

PicoSure is one of the leading lasers in Singapore. What makes PicoSure stand out from the competition is that it utilizes a 755nm wavelength that specifically targets melanin over hemoglobin. This means that PicoSure is ideal for treating pigmentary conditions with minimal collateral damage.

The 755nm energy relies very little on the photothermal action of the long-pulsed machine, as it relies mainly on the photomechanical impact. Thermal damage to the skin is minimal, yet it does not compromise on the efficacy of the treatment outcome.

In addition, the 755nm wavelength is able to break down tattoo inks that are notoriously difficult to get rid of, such as black, blue, and green.

PicoSure Laser is markedly different from the rest of the Pico Laser because of its unique patented Focus Lens Array. The Focus Lens Array uses a diffractive lens to rejuvenate the skin with virtually no downtime.

The unique mechanism of action shatters the stubborn pigments under the skin by creating laser-induced optical breakdown in the epidermis without damaging the skin surface. They create intra-epidermal cavities and generate pressure waves that impact surrounding cells, signaling the skin to induce an inflammatory response to begin the healing process.

After a few sessions, patients will be able to observe improvements in the skin texture with visible brightening of the skin. The stimulation of collagen and elastin in the skin reduces the appearance of acne scars, fine lines, and wrinkles.
