On the top-notch technology stage of the medical beauty industry, the Nd: YAG laser system is like a superhero with unique skills. It carries a secret weapon with a wavelength of 1064nm, which can easily penetrate the surface of the skin, directly targeting the root cause of the problem, while treating the epidermis gently. This versatile athlete excels in various battlefields such as hair removal, removing redness and blood streaks, skin rejuvenation, and spot lightening, making him the Swiss Army Knife of the medical beauty industry. With the continuous upgrading of technology, Nd: YAG laser has evolved from a lone warrior to an all-around team that integrates treatment, repair, and anti-aging. It uses non-invasive and gentle methods to bring safe and efficient beauty solutions to people who pursue beauty, perfectly interpreting what technology makes beauty simpler. Whether it’s driving away stubborn hair or smoothing out the traces of time, this laser device always gives unexpected surprises.

In practical clinical applications, the versatility of Nd: YAG laser is particularly significant. For example, by adjusting pulse width and energy parameters, doctors can accurately destroy hair follicles to achieve permanent hair removal, while improving rosacea or spider nevi targeting hemoglobin; Its non exfoliative thermal stimulation can also promote collagen remodeling, which is used to tighten the skin and improve wrinkles. In addition, when treating the high incidence of melasma and Ota nevus in the Asian population, Nd: YAG laser reduces the risk of pigmentation with longer wavelengths, demonstrating good adaptability to different skin tones. The feature of “one machine for multiple uses” not only improves clinical efficiency, but also promotes the development trend of personalized medical beauty treatment.

Why Choose ND:YAG? Four Irreplaceable Treatment Advantages

Advantages

ND YAG LASER machine is a commonly used medical and aesthetic laser technology that can be used to solve a variety of skin problems and diseases. It has the advantage of penetrating deeply into the skin for a noticeable and long-lasting therapeutic effect.

Good results

Smaller pigment particles for easier absorption and elimination by the body.

High level of comfort

The laser penetrates directly into the skin and is easily absorbed by the melanin, greatly reducing pain during treatment and providing the highest level of comfort of any laser items.

Safety

While breaking up the pigment particles, the laser does not cause any damage to the surrounding skin tissue, reducing the risk of damage to normal tissue and reducing the probability of hyperpigmentation.

Versatile

The four different kinds of handles cover a wide range of treatments including tattoo removal, skin dullness improvement, skin rejuvenation, acne removal and blackhead removal, etc.

How the Nd:YAG laser works

The functionality is based on a chemical-physical principle. During so-called pumping, the neodymium on the laser crystal is excited. This means that the neodymium is supplied with light in a targeted manner. This light contains a certain amount of energy that converts the electrons in the neodymium atoms to another energy level. Due to this physical excitation, the neodymium itself finally emits radiation in the form of a photon. The emitted photons are reflected and forth in the so-called laser cavity. They use the eponymous LASER effect (Light Amplification with Stimulated Emission of Radiation): every photon that passes an electron at a high energy level stimulates the emission of another photon. This equals the first in frequency, phase, polarization and direction. This increases the radiation enormously.

To better illustrate the usefulness of this emitted radiation, here’s an example from medical practice: If a doctor wants to kill diseased cells in his patient, he can aim the Nd:YAG laser at that spot. The laser irradiates the desired area, generating a great deal of heat in the cells and thus leading to the death of the diseased tissue. It is also possible to work in somewhat deeper tissue layers.

Analysis of Clinical Indications and Treatment Range of ND:YAG Laser

• Leather pigments: Ota mole, Ito mole, Mongolian spot, cheekbone brown blue mole
• Epidermal pigmentation: coffee spots, freckles, seborrheic keratosis, sunspots, various pigmented nevi, post inflammatory pigmentation, etc.
• Mixed spots: melasma spots
• Exogenous pigment: tattoo, eyebrow tattoo, eyeliner tattoo, etc.
• Tender skin, refine pores, fade acne scars, brighten and even skin tone, remove blackheads, and control oil.
• Stimulate collagen regeneration, delay aging, fade fine lines, and tighten the skin.

Safety Guidelines and Precautions for Clinical Application of Nd:YAG Laser

Nd: YAG laser is widely used in the field of medical beauty, but due to its specific wavelength and energy characteristics, strict adherence to clinical standards is required during treatment to ensure safety and effectiveness.

Pre-operative precautions

A detailed skin assessment must be conducted, including the patient’s skin type (Fitzpatrick classification), photosensitivity of the treatment area, medical history (such as scar constitution, photosensitive diseases), and whether they are currently taking photosensitive drugs (such as retinoic acid, tetracycline antibiotics). For patients with dark skin color (IV-VI type), careful adjustment of energy parameters is necessary to reduce the risk of pigmentation or hypopigmentation. In addition, strong sun exposure or the use of tanning products should be avoided 4-6 weeks before treatment, and it is recommended to discontinue irritating skincare products (such as acid, salicylic acid, etc.) 2 weeks before surgery to reduce postoperative inflammatory reactions.

In Treatment

During the treatment process, the operator needs to accurately set parameters based on different indications, such as pulse width, energy density, and spot size. For example, vascular lesions such as erythema and rosacea typically use lower energy and longer pulse widths to reduce the risk of purpura; However, pigmentary diseases such as Ota nevus and tattoos require the use of high peak energy in Q-switching mode to ensure the explosive effect of pigment particles.

Postoperative Care

Including immediate cold compress to reduce redness and swelling, use of medical repair dressings to promote skin barrier recovery, and strict sun protection (SPF30+or above) for at least 4 weeks to avoid post inflammatory pigmentation (PIH). Avoid high temperature environments (such as saunas and vigorous exercise) for 1-2 days after treatment, and suspend the use of irritating skincare products until the skin is completely repaired. For possible adverse reactions such as blisters, scabs, or transient pigmentation abnormalities, patients should be informed in advance and a follow-up plan should be developed to ensure timely intervention.
