Laser cu diodă Lumenis LightSheer® QUATTRO

Lumenis diode laser LightSheer® QUATTRO™ occupies an important position in the field of medical beauty. With advanced technology and excellent performance, it has brought high-quality solutions to many beauty lovers. The following will be introduced in detail from the aspects of principle, function and effect.

I. Working principle

(I) Core laser technology and photothermal conversion

LightSheer® QUATTRO™ uses advanced diode laser technology and has two wavelengths of 805nm and 1060nm. When the device emits a laser beam, its energy is highly absorbed by specific pigments (mainly melanin) in hair and skin. Based on the principle of selective photothermal action, these absorbed light energies are quickly converted into heat energy. Taking hair removal as an example, melanin in hair follicles absorbs the heat energy generated by laser energy, which can accurately destroy hair follicle tissue, making it lose the ability to regenerate hair, while minimizing damage to surrounding normal skin tissue. When treating pigmented lesions, the heat energy generated by the laser can decompose pigment particles in the skin, such as those in freckles and sun spots, making it easier for the human immune system to identify and remove these pigment fragments.

(II) Unique vacuum suction auxiliary mechanism

The device uses vacuum suction technology to generate negative pressure to suck up the epidermis during treatment. This operation has multiple effects. First, it shortens the distance between the hair follicles and the laser emission position, so that the laser energy can be transmitted to the hair follicles more directly and efficiently, enhancing the destructive effect on the hair follicles; second, it can reduce the absorption of laser energy by the epidermis, so that more energy can be focused on the target melanin, improving the targeted treatment; third, it effectively reduces the risk of epidermal burns and provides a guarantee for the safety of treatment.

II. Functional features

(I) High-efficiency laser hair removal function

Suitable for all skin types: The two wavelengths of 805nm and 1060nm make LightSheer® QUATTRO™ suitable for all skin types, including dark skin and bronze skin. This greatly broadens the applicable population. Whether it is fair skin, healthy wheat-colored skin or dark skin, the device can be used to achieve the ideal hair removal effect.

Full coverage of hair types: Whether it is coarse hair or fine hair, it can be effectively treated. The 400ms pulse energy can easily deal with fine hair that is difficult to remove with general laser hair removal. From ordinary hair in the armpits, thighs, calves and other parts to hair near the upper and lower lips, areola, perineum, anus, and even facial fine hair, permanent hair removal can be achieved to meet the hair removal needs of different parts.

(II) Multi-directional skin treatment function

Pigmented lesion treatment: It can effectively remove epidermal pigmented lesions, such as age spots, sun spots, freckles, etc. The high energy of the laser breaks down pigment particles into tiny fragments, which can be recognized and removed by the human immune system, thereby improving skin quality, brightening skin tone, and restoring uniform skin tone.

Vascular lesion treatment: It can treat some minor vascular lesions to a certain extent, such as small spider-web varicose veins on the face and legs. The laser energy is absorbed by the hemoglobin in the blood vessels, causing the blood vessels to close and contract due to heat, and eventually absorbed by the human body.

Firming and skin rejuvenation: During the treatment, the thermal effect of the laser will stimulate the proliferation and remodeling of collagen in the dermis of the skin. Long-term use helps reduce wrinkles, improve skin firmness, make the skin smoother and more delicate, and achieve the effect of skin rejuvenation.

III. Advantages

(I) Technical advantages

High energy and large spot synergy: The device can provide higher energy output and adopts a large spot design, such as a 22x35mm large-area treatment probe, which can quickly cover a larger treatment area, shorten the treatment time, and improve treatment efficiency. High energy ensures sufficient effect on the target tissue, which can more effectively destroy hair follicles during hair removal and better act on the lesion site during skin treatment.

Flexible parameter adjustment: The operator can flexibly adjust multiple treatment parameters such as pulse width, energy density, and spot size according to the patient's specific conditions, such as skin type, hair thickness, and degree of lesions. This personalized parameter setting can formulate more accurate and optimized treatment plans to meet the diverse needs of different patients
