What Is A Long Pulsed Nd:YAG Laser?

You encounter advanced technology when you choose long pulse nd yag laser equipment for your skin treatments. This device uses a unique wavelength of light to target deeper layers of your skin while minimizing risk to the surface. Professionals often recommend it for clients with darker skin tones. You benefit from its precise action, making it a trusted solution for various dermatological needs.

How Does a Long Pulsed Nd:YAG Laser Work?

Wavelength and Pulse Duration

When you use long pulse nd yag laser equipment, you benefit from a device that operates at a wavelength of 1064 nanometers (nm). This wavelength stands out because it penetrates deeper into your skin compared to other lasers. The laser’s energy targets specific structures beneath the surface while minimizing the risk of damage to the outer layers.

You will notice that the pulse duration, or the length of time the laser emits energy, can range from 15 to 30 milliseconds (ms) in most clinical settings. For certain treatments, such as targeting blood vessels of different sizes, the pulse duration may vary from 1 to 10 ms. Longer pulse durations work best for larger vessels, while shorter durations suit smaller targets.

●1064 nm wavelength reaches deep skin layers.
●Pulse durations typically range from 15–30 ms.
●For vessel treatments, durations can vary from 1–10 ms depending on vessel size.

This combination of wavelength and pulse duration allows you to achieve precise results with minimal discomfort.

Mechanism of Action

Long pulse nd yag laser equipment uses a process called selective photothermolysis. When you undergo treatment, the laser targets specific chromophores in your skin. Chromophores are natural molecules like melanin, water, and oxyhemoglobin. These molecules absorb the laser’s light and convert it into heat.

●The laser energy heats the targeted chromophores.
●This heat destroys unwanted structures, such as hair follicles or blood vessels.
●The surrounding skin remains safe because the laser’s wavelength and pulse duration are carefully chosen.

You experience effective treatment because the laser focuses its energy only where needed. This approach ensures that you get the desired results while protecting healthy tissue.

What Conditions Can Long Pulse Nd Yag Laser Equipment Treat?

This technology targets blood vessels beneath your skin, including spider veins, hemangiomas, and telangiectasia. The laser’s deep penetration and selective targeting make it effective for both small and larger vessels.

● A study using the 1064-nm long-pulsed Nd:YAG laser reported that 80% of patients achieved greater than 75% clearing of larger-diameter vessels (up to 4 mm) after one to three treatments.
● You experience minimal downtime and low risk of skin damage, even if you have a darker skin tone.

Hair Removal

Long pulse nd yag laser equipment offers a reliable solution for long-term hair reduction. You benefit from its ability to target hair follicles deep within your skin, making it suitable for all skin types, including those with higher melanin levels.

Research has shown that the long-pulsed Nd:YAG laser can achieve a mean hair reduction of up to 80%, with one study reporting a 79.4% decrease in hair count at a six-month follow-up, indicating its effectiveness in hair removal.

Acne and Scars

You can use long pulse nd yag laser equipment to address acne and post-acne scars. The laser energy penetrates your skin, reducing inflammation and stimulating collagen production. This process helps smooth out scars and improves overall skin texture.

● A study evaluated the clinical efficacy, safety, and long-term effects of Long Pulsed Nd:YAG lasers in treating acne scars.
● 86.6% of patients showed a positive response, with 26.6% achieving excellent results.
● 60% of patients had a moderate-to-good response, while only 13.4% had a fair response.
● The treatment was deemed efficient and safe, particularly for mild to moderate post-acne scars, with minimal downtime and transient side effects.

Skin Rejuvenation

You can achieve noticeable improvements in your skin’s texture and tone with long pulse nd yag laser equipment. This technology stimulates collagen production deep within your skin. As a result, you see smoother, firmer, and more youthful-looking skin over time. Many patients choose this treatment to address fine lines, enlarged pores, and uneven skin tone.
