Unlimited Black Cards! A Mysterious and Wealthy Young Lady!

The sofa in the reception area is made of dark brown genuine leather, paired with a solid wood coffee table in the same color scheme. On the coffee table is a set of exquisite white porcelain tea set, and the green leaves of the floor plant next to it are bright and vibrant, adding a touch of vitality to the simple space.

The wall displays certificates of the institute's core research achievements, including national invention patent certificates, international beauty technology innovation awards, and cooperation authorization letters with several well-known medical institutions. The team introduction section below clearly shows photos, educational backgrounds, and research fields of the core members, all of whom hold doctoral or master's degrees from top medical universities at home and abroad.

"This is our experimental sample display area." Dr. Chen led Jiang Wenxi to the glass display case on the right side of the hall. The display case was made of UV-resistant glass and had soft warm spotlights installed inside, illuminating the various experimental samples of beauty products neatly arranged inside.

The samples are divided into different research and development stages, distinguished by different colored labels: blue labels represent "basic research and development stage", yellow labels represent "experimental optimization stage", and red labels represent "clinical trial stage".

Each sample bottle is clearly labeled with the product name, core ingredients, R&D leader, and R&D date, and is accompanied by a brief efficacy description card.

"These are the research and development results of our team in recent years, covering multiple categories such as serums, masks, and lotions. The core direction is high-end bio-cosmetics, focusing on both safety and efficacy."

Dr. Chen pointed to a plant stem cell mask sample labeled "clinical trial stage" and introduced it, "We have completed the initial safety test of this mask, and it has a significant effect on improving fine lines and enhancing skin firmness. We are currently advancing large-scale clinical trials."

Ascending the clean and tidy corridor to the second floor, the walls on both sides are adorned with posters on various scientific research themes, including cell structure diagrams, extraction processes of bioactive ingredients, and skin barrier repair mechanisms. The posters are rich in illustrations and text, and are highly professional.

This is the core research and development area, which uses fully transparent tempered glass partitions. The glass is covered with frosted "Research and Development Area, No Unauthorized Entry" signs. Through the glass, you can clearly see the researchers inside, wearing white lab coats, focusing on operating the experimental equipment. Each person's lab coat is printed with the institute's logo and their personal name tag.

"Ms. Jiang, the second floor is our main experimental area, which is divided into three core zones: an active ingredient extraction laboratory, a formula development laboratory, and a safety testing laboratory. Each zone is equipped with an independent ventilation system and a temperature and humidity control system to ensure the stability of the experimental environment."

Dr. Chen explained, adjusting his glasses as he led Jiang Wenxi to the entrance of the active ingredient extraction laboratory, pointing to the equipment inside through the glass.

"Look, that's a German-imported low-temperature extraction instrument, model IKA RV 10 digital. It can lower the temperature to -20℃ and achieve an extraction precision of 0.01mg. Our team completes most of our plant active ingredient extraction experiments using it."

"That machine next to us is a high-pressure separator, with a maximum pressure of 50MPa. It can effectively separate high-purity active ingredients and prevent impurities from mixing in and affecting the product's effectiveness."

Jiang Wenxi looked in the direction he pointed and saw that the experimenters were wearing sterile gloves and carefully putting the processed plant materials into the low-temperature extraction instrument. Their movements were gentle and standardized, and every step was strictly carried out in accordance with the operation manual.

Various reagent bottles are neatly arranged on the lab table, with clear labels. They are categorized and stored on a dedicated reagent rack. The electronic balance next to it displays values ​​accurate to four decimal places. The experimental data in the notebook is written neatly and clearly.

Jiang Wenxi leaned closer to the glass and carefully observed the experimenters' operations. She saw that their movements were standardized and skillful, the instruments on the experimental table were neatly arranged, the reagent bottles were clearly labeled, and the entire experimental process was orderly.

She noticed that the laboratory's ventilation and temperature and humidity control systems were functioning normally, and these kinds of details best reflect the institute's level of professionalism.

Afterwards, Dr. Chen led Jiang Wenxi to the entrance of the formula development laboratory. The researchers there were gathered around the lab bench, discussing the experimental data on the computer screen. Each person had a notebook in front of them, jotting down key information from time to time. Various beakers, test tubes, pipettes, and a precision ultrasonic disperser were placed on the lab bench, running at a steady speed and emitting a soft hum.

"Our formula development is based on a large amount of experimental data, and the ingredient ratio of each product has been optimized and adjusted hundreds of times," Dr. Chen explained. "Look at the anti-aging essence they are developing. The core ingredient is recombinant human collagen, which needs to be precisely controlled in proportion to other auxiliary ingredients to achieve the best anti-aging effect."

Next, the group entered the safety testing laboratory, where the equipment was even more sophisticated and complex. Dr. Chen pointed to a large piece of equipment and explained:

"This is a skin irritation testing instrument imported from the United States, model VitroSkin ES-60. It can simulate the physiological environment of human skin and accurately detect the skin irritation of products, with an accuracy rate of over 98%. The one next to it is a cell culture incubator with a temperature control accuracy of ±0.1℃ and humidity control at around 95%. Different types of human skin cells are cultured inside for cytotoxicity experiments of products."

He paused, then added, "All the safety tests for our products are completed here, including skin irritation tests, cytotoxicity tests, heavy metal tests, hormone tests, etc. Every indicator is strictly implemented in accordance with national standards to ensure that the safety of the products meets the requirements. In particular, for people with sensitive skin, we will add multiple repeated tests to avoid any safety hazards."

Jiang Wenxi noticed that a professional pure water machine was placed in the corner of the laboratory. The water quality test report next to it showed that the resistivity of the water reached 18.2 MΩ·cm, which met the first-class water standard for laboratories. Such details are enough to show the institute’s strict requirements for the experimental environment.

After visiting the experimental area on the second floor, the group went up the stairs to the office area and archives on the third floor.
