2940nm Erbium YAG Laser Machine

Advanced Technology Behind the 2940nm Erbium YAG Laser Machine

The 2940nm Erbium YAG Laser Machine from SANHE Laser utilizes advanced Er:YAG laser technology with a wavelength of 2940 nm, part of the mid-infrared spectrum. This wavelength is highly absorbed by water, making it exceptionally effective for precise skin resurfacing and rejuvenation treatments.

By targeting water molecules in the skin, the 2940 nm laser enables controlled ablation of the superficial epidermis with minimal thermal damage (only 30–50 μm). This ensures exceptional precision, safety, and uniform results.

Compared with conventional resurfacing technologies, the Erbium YAG Laser Machine offers faster recovery, minimal downtime, and superior skin renewal outcomes — making it an ideal solution for dermatologists seeking both performance and patient comfort.

Advantages of 2940nm Erbium YAG Laser Machine

1. With precised, safe micrometer-level evaporation thickness, skin recovers very fast after treatment.

2. Minimal thermal damage to surrounding tissues, and the risk of scar and pigmentation is also mini- mized.

3. For both epidermis and deep layer dermabrasion;

4. Minimal pain, no epidermis anesthesia is needed during treatment.

5. With convenient screen instructions, system can provide proper parameters according to treatment type and body part to be treated. Beginners can also operate machine well, on professional mode parame- ter screen, user can SAVE parameters in system.

6. With precised Fractional Handpiece, it can minimize skin injury, and skin can recover fast after treatment.

7. Professional Dehumidifier can minimize laser energy loss in transmission during treatment and in- crease laser service life.

Key Functions and Clinical Applications of the 2940nm Erbium YAG Laser Machine

1. Reduction of Jowl Fat and Nasolabial Folds — Effective Skin Tightening Around the Mouth

The 2940nm erbium YAG laser machine from SANHE Laser adopts a non-ablative treatment mode that heats the oral mucosa to 60–65℃, stimulating deep collagen regeneration and mucosal contraction. This process helps tighten the skin surrounding the mouth, effectively reducing jowl fat and nasolabial folds for a natural anti-aging effect. The treatment achieves visible tightening results with minimal discomfort and no downtime.

2. Er:YAG Laser Cold Peeling Technology — Gentle Yet Powerful Skin Resurfacing

With its advanced cold ablation feature, the erbium YAG laser machine removes the superficial layer of the skin precisely and evenly. This process promotes skin regeneration, leading to brighter skin tone, smaller pores, wrinkle reduction, and scar improvement.

Unlike traditional ablative lasers, it minimizes thermal damage and pain—no epidermal anesthesia is required, and patients experience short recovery time after treatment. This makes it ideal for medical aesthetic clinics offering safe, effective, and comfortable skin resurfacing solutions.

3. Eyelid Lifting and Eye Bag Reduction — Safe, Non-Invasive Rejuvenation

Equipped with a superficial epidermis ablation function, the erbium YAG laser machine can be applied for eyelid lifting and eye bag reduction. One major safety advantage is that the laser does not penetrate the skin, ensuring no harm to the eyes during treatment. This makes it a preferred option for delicate periocular skin tightening and rejuvenation procedures.

4. Pigment Spot Removal — Precise and Fast Freckle & Age Spot Treatment

The Er:YAG laser ablation technology is highly effective in removing epidermal pigment spots, such as freckles, sunspots, and age spots. Its precise and controlled ablation allows rapid pigment removal without excessive heat damage, achieving uniform skin tone and refreshed appearance.

5. Scar and Stretch Mark Reduction — Strengthened Ablation for Deep Skin Renewal

By increasing laser energy output, the erbium YAG laser machine OEM can perform enhanced ablation to target scars, acne marks, and stretch marks. The treatment encourages new collagen formation and tissue remodeling, visibly improving skin texture and elasticity over time. Clinics can adjust parameters flexibly to meet different treatment demands.

6. Skin Whitening and Vegetation Removal — Versatile Clinical Applications

The Er:YAG laser also provides reliable solutions for skin whitening treatments on sensitive areas such as the areola and bikini line. Additionally, it can evaporate benign skin growths or vegetations efficiently, ensuring precise removal and clean skin recovery. These multifunctional capabilities make the erbium YAG laser machine OEM a highly versatile device for dermatology and aesthetic medicine.
