Alexandrite Pico Laser Treatment for Pigmentation, Acne Scars and Tattoo Removal
We offer a range of treatments in Singapore utilizing the Alexandrite Pico Laser, an alternative picosecond laser. The Pico laser is known for its unique technology and effectiveness in using the picosecond laser treatment of pigmentation, acne scars, and colour tattoo removal.
What is Alexandrite Pico laser?
Alexandrite Pico laser is a new generation laser that delivers ultrashort laser pulses in picoseconds (10−12) whereas compared to the traditional Q-switched laser, which delivers laser pulses in nanoseconds. It is a 755nm wavelength Alexandrite laser that leverages on picosecond laser technology to manage the treatment of hyperpigmentation, acne scars, and colour tattoo with optimal results.
What makes Alexandrite Pico Laser so unique?
Unlike other picosecond devices, the Alexandrite Pico Laser utilizes a 755 nm wavelength that specifically targets melanin. This wavelength absorbs less blood compared to the 1064 nm wavelength. In trillionths of a second, the 755 nm energy relies less on photothermal action than longer-pulsed devices, instead creating an intense photomechanical impact.
This technology not only spares the skin from high thermal damage, but it also disrupts the target chromophore more effectively, achieving increased clearance with less energy and fewer treatments. In layman’s terms, it is an ideal treatment for pigmentary conditions, as more Pico laser shots can be delivered into the dermis.
The Alexandrite Pico Laser has additional functions with its patented Focus Lens Array. This unique technology delivers 755 nm energy to the skin in a targeted manner. The combination of high and low-intensity energy effectively lightens and breaks down stubborn pigments beneath the skin. The high energy creates Laser-Induced Optical Breakdown (LIOB) in the epidermis without damaging the skin's surface.
LIOB form and absorb incoming energy, expanding so rapidly that they generate pressure waves transmitting into the dermis. This pressure squeezes surrounding cells, simulating a pressure injury that activates cell signaling and enhances the inflammatory healing response. Consequently, this process boosts collagen and elastin production in the dermis without energy damage passing through the dermoepidermal junction.
Moreover, the 755nm wavelength device effectively breaks down tattoo inks that are challenging to remove, like black, blue, and green. Patients treated with Focus typically experience only a few hours of mild redness.
Alexandrite Pico Laser : Is It a More Effective Pigmentation Solution?
Traditional lasers use photothermal energy to shatter pigments, while the Pico laser disrupts stubborn pigments by emitting short pulses. This is to treat a wide range of skin pigmentation issues such as freckles, sun spots, and melasma. It uses ultra-short pulse bursts of energy to break down pigments into smaller dust-like particles that can be absorbed by the lymphatic system and eliminated naturally. The shorter exposure of the Pico laser also significantly reduces the risks of burning, scarring and other adverse side effects of traditional laser treatments.
The Tool For Colour Tattoo Removal
Apart from skin rejuvenation, acne scar removal and hyperpigmentation treatment, the Pico laser is also effective for removing colour tattoos. Its strength lies in its ability to shatter tattoo ink particles effectively. By targeting the laser on the tattoo ink particles in picoseconds, it can effectively clear stubborn ink colours such as orange, yellow, red, blue, purple and green.
A Gentle Alternative for Acne Scar Treatment
This 755nm Alexandrite Pico Laser is one of the FDA approved treatments for pigmentation, skin texture and acne scars treatment. The Focus Lens is a hexagonal, closed packed diffractive lens array which is 500μm centre to centre. More energy is concentrated in the small spot, which makes it 20x more powerful than normal lens.
By delivering short Pico laser pulses that are 10 times shorter in duration than a traditional Q-switched laser, more laser shots can be delivered with each pulse staying on the skin for a shorter duration. This means that less heat is generated in the skin, causing significantly less damage to the skin tissue.
Through its targeted mode of energy delivery, this Pico laser reaches the dermis layer, improving acne scars with the formation of new collagen and elastin production.
Dr Thean's Advice & Recommendation
The 755nm Alexandrite wavelength is an ideal balance between 532nm and 1064nm pico laser. It selectively targets melanin and blood vessels without damaging the skin's surface. But I found that by combining a variety of lasers with this Alexandrite Pico Laser, I can target the different layers of the skin and achieve an optimal result.
