I. Introduction to Fractional Laser Fractional laser is the latest and hottest skin rejuvenation technology in the past two years, and it has garnered the most attention in the global dermatology community. In Taiwan, it is known as飛梭鐳射(Fraxel laser), while in mainland China, it is called點陣激光(fractional laser). Fractional laser combines the rapid and significant effects of invasive treatments with the advantages of non-invasive treatments, such as minimal side effects and short recovery time, integrating the best of both worlds. II. How Fractional Laser Works In scar removal, especially for hypertrophic scars, acne scars, and stretch marks, fractional laser technology outperforms similar products. With its milestone patented technology, the application of fractional laser makes laser scar removal safer and more effective. Each treatment session takes only tens of minutes, without affecting work, study, or daily life. Moreover, fractional laser also excels in treating acne, wrinkles, and pigmentation. It disperses the originally concentrated laser beam into dozens to hundreds of smaller microbeams, allowing the laser to reach the dermis layer directly. This ensures the integrity of the skin's stratum corneum, avoids damage to the epidermis, and deeply penetrates the skin to stimulate collagen production and reorganization. Additionally, the contraction and repair of the conical pores result in visibly plump, firm, and tender skin, making the skin finer, smoother, and more elastic, leading to a qualitative improvement in skin texture. At the same time, fractional laser breaks through the limitations of traditional laser resurfacing, representing a breakthrough advancement in the field of medical optics. Fractional is merely a mode of laser emission; fractional laser outputs a single-wavelength laser in the form of a matrix-arranged microbeam. It offers up to five rectangular patterns (circle, square, rectangle, diamond, triangle), each suitable for treating different areas and skin types. III. Product Advantages 1. Quickly improves skin texture, tightens the skin, reduces enlarged pores, and leaves the skin as smooth and tender as water! This technology is a perfect clinical combination of multiple modes in Bo'ai's laser dermatology department, representing internationally leading wrinkle removal and skin rejuvenation technology. 2. The lessons learned from ultra-pulsed fractional laser have elevated laser beauty treatments to a new level. Doctors can use its unique functions for artistic comprehensive treatments, meeting the unique body shape, contour, and beauty needs of patients in a single session. 3. Ultra-pulsed micro-bridge fractional laser addresses the shortcomings of treatment technologies that require long recovery periods, catering to the specific requirements of each patient. 4. Utilizing a single artistic comprehensive treatment allows for more precise control over clinical and aesthetic outcomes, achieving more significant and accurate results with shorter recovery times. 5. Effectively avoids side effects such as thermal damage while promoting skin healing. IV. Applicable Scope 1.
