Core Viewpoint - The article discusses the classification and application of various laser technologies in the medical aesthetics industry, emphasizing that different laser types serve distinct treatment paths and are complementary in a mature medical aesthetic center [19]. Group 1: Laser Types and Mechanisms - Q-switched lasers utilize nanosecond energy pulses to break down melanin particles, effective for treating pigmentation issues like freckles and tattoos [3]. - Picosecond lasers further shorten pulse width to picoseconds, allowing for deeper penetration and collagen activation, suitable for conditions like melasma and acne scars [4][5]. - CO₂ fractional lasers operate at a wavelength of 10600 nm, vaporizing water in the skin to treat deeper skin issues and induce collagen regeneration, making them ideal for significant skin reconstruction [6][8]. - Er:YAG lasers, with a wavelength of 2940 nm, focus on superficial skin layers, providing precise exfoliation with minimal thermal damage, suitable for fine lines and superficial scars [9][12]. Group 2: Applications and Benefits - Q-switched lasers are foundational tools for pigment-related treatments due to their powerful pigment destruction capabilities [3]. - Picosecond lasers are versatile, often used in fractional mode for acne scars and skin texture improvement [5]. - CO₂ lasers have a longer recovery period but offer unique advantages in structural skin repair [8]. - Er:YAG lasers are preferred for patients seeking minimal downtime and precise treatment of superficial skin issues [12][14]. Group 3: Market Overview - As of June 2025, 77 laser-related medical aesthetic devices have been approved for market use in China, indicating a growing industry with diverse technological offerings [16][17].

Core Viewpoint - The recent technological breakthrough by the smart medical beauty brand Weixinmei, featuring an Abbe number of 64.06 crystal probe and 0.2nm precision processing, sets a new industry standard for AI medical beauty equipment [1][2]. Group 1: Technological Advancements - The Abbe number of 64.06 indicates minimal light energy scattering or refraction deviation, ensuring high focus and stability during energy transmission, which is crucial for high-frequency oscillation, RF thermal energy, and ion penetration projects [2]. - The crystal probe is processed with a surface error of no more than 0.2nm, achieving a level comparable to some optical chip processes, significantly improving energy injection into the dermis layer while reducing thermal diffusion and avoiding skin damage [3]. Group 2: Performance Improvements - The new technology offers a 37% increase in energy penetration depth within the same time frame, significantly enhancing the efficiency of energy delivery [5]. - The precise temperature control of the skin surface minimizes traditional issues such as excessive heat sensation, pain, and redness during treatment [5]. - The crystal structure is durable, with a lifespan of over 800 hours for a single probe, indicating a robust material design [5]. Group 3: Industry Impact - Weixinmei aims to redefine "smart medical beauty" through systematic technological reconstruction, focusing on critical details that contribute to a leading global standard in intelligent skincare [5]. - The company is not only developing equipment but also building the foundational infrastructure for intelligent skincare over the next decade, encompassing crystal probes, energy systems, algorithm optimization, data empowerment, membership systems, and point-sharing [5][6].
