Nd: ヤグレーザー

の Nd:YAG (Neodymium-doped Yttrium Aluminum Garnet) laser is one of the most widely used lasers in aesthetic medicine. It operates at a wavelength of 1064nm (and sometimes at 532nm), making it versatile for a variety of treatments, including hair removal、 肌の若返り、 そして pigmentation correction. The Nd:YAG laser is effective for deep penetration of the skin layers, which allows it to treat both superficial and deeper skin conditions.

This laser is known for its ability to treat darker skin types (Fitzpatrick IV-VI) more safely compared to other lasers, making it a popular choice in aesthetic clinics and dermatology practices.

🔎 Applications of Nd:YAG Laser

1. Hair Removal

The Nd:YAG laser provides safe and effective hair removal for all skin types, particularly dark skin. It uses a longer wavelength (1064nm) to penetrate deep into the skin, targeting hair follicles without causing damage to the surrounding skin tissue.

• Effective on: All hair types and skin colors

• Session Time: 20–30 minutes

• Results: Long-lasting hair reduction after 6–8 sessions

2. Skin Rejuvenation

The Nd:YAG laser is commonly used for skin rejuvenation treatments, as it stimulates collagen and elastin production. This helps reduce fine lines, wrinkles, and improves skin texture, tone, and elasticity.

• ターゲット: Fine lines, wrinkles, sagging skin, and overall skin texture.

• Session Time: 30–45 minutes

• 頻度: 4–6 sessions, spaced 2–3 weeks apart

• Results: Younger, firmer skin with improved elasticity and texture.

3. Pigmentation Treatment

The Nd:YAG laser is ideal for treating pigmentation issues like sunspots, age spots, and melasma. The laser’s wavelength effectively breaks down the pigment particles, which are then absorbed by the body.

• Effective for: Sunspots, freckles, age spots, and melasma.

• Session Time: 20–30 minutes

• 頻度: 3–5 sessions, spaced 2–3 weeks apart

• Results: Reduced appearance of pigmentation, even skin tone.

4. Vascular Treatments

The Nd:YAG laser can treat vascular conditions such as spider veins、 broken capillaries、 そして rosacea. By targeting the blood vessels, the laser helps to shrink and close the veins, leading to clearer skin.

• Effective for: Spider veins, broken capillaries, and rosacea.

• Session Time: 15–30 minutes

• 頻度: 2–4 sessions

• Results: Clearer, healthier skin.
