In the field of medical beauty, laser therapy has become one of the mainstream methods to improve skin problems, but the accompanying pain has deterred many beauty seekers. Skin air cooling machine have emerged, and this seemingly simple yet technologically advanced device is quietly changing the medical beauty experience.
It provides comprehensive cold protection for the skin before, during, and after laser treatment through precise cooling technology, allowing beauty transformation to no longer be accompanied by unbearable pain.
1.Basic Principles and Technical Features
It uses a compression device to compress air and then sprays cold air through a refrigeration device. Its core working principle is to continuously provide cold protection to the epidermis during laser or other phototherapy beauty processes, achieving the goal of protecting the epidermis and reducing pain, while allowing high energy density to act on the target tissue without damaging the epidermis.
The technical design of modern skin air coolers is very precise. Taking typical models of air cooling machines as an example, they are usually able to provide cold air ranging from -4℃ to -30℃. With preset cooling levels (usually adjustable from 1-6 levels) and cooling times (1-60 minutes), operators can make precise adjustments based on the patient’s comfort and treatment needs.
These devices are also equipped with infrared temperature sensors and intelligent control modules, which can precisely adjust the target temperature to achieve therapeutic effects while preventing skin frostbite.
2.Core Functions of Skin Air Cooling Machine
2.1 Redness Reduction
It can quickly promote the contraction of capillaries in the treatment area through precise low-temperature airflow. This physiological response directly reduces the blood flow and vascular permeability of local tissues, thereby effectively alleviating common erythema reactions after surgery with energy devices such as laser or radiofrequency.
Active cooling control not only shortens the natural regression cycle of erythema, but also provides immediate comfort to patients visually, effectively improving the appearance of the skin and patient satisfaction after treatment.
2.2 Edema Relief
Thermal injury is the core factor causing tissue fluid leakage and local edema. The continuous cooling implemented by the air cooler before, during, and after surgery can limit the diffusion and accumulation of heat energy in the epidermis and underlying tissues from the source.
By reducing tissue metabolic rate and cell permeability, it significantly reduces the release of inflammatory mediators and the exudation of tissue fluid, effectively preventing and reducing the formation of edema, and accelerating the normal recovery of facial or treatment site contours.
2.3 Inhibition of Scab Formation
Scab formation is usually a sign of excessive heat damage to the epidermis and rapid loss of water. The intervention of the air cooler provides a crucial thermal buffer zone for the epidermis, ensuring that laser energy can act on deep target tissues while maximizing the protection of epidermal integrity. By maintaining the activity and humidity of epidermal cells, it fundamentally reduces the risk of blistering and carbonization of the epidermis, resulting in thinner or even no scab formation after surgery. This lays a solid foundation for shorter recovery periods and lower pigmentation risks in the future.
2.4 Pain Management
Low temperature has a natural sedative and inhibitory effect on nerve endings. The continuous cold air blown out by the air cooler forms an effective sensory shielding layer on the surface of the skin, which can significantly reduce the sensitivity of pain receptors and slow down the transmission speed of nerve signals.
This non pharmacological physical analgesia method greatly alleviates the pain and burning sensation experienced by patients during various invasive or non-invasive treatments, making high-energy therapy more tolerable.
2.5 Laser Treatment with Collaborative Cooling
This is the core mission of the air cooler. When working in conjunction with various laser devices such as picosecond, dot matrix, hair removal lasers, etc., the air cooler implements dynamic and real-time synchronous cooling. It can neutralize the instantaneous high heat generated by laser pulses, protect the epidermis from collateral damage, and allow doctors to safely use higher energy parameters to pursue optimal therapeutic effects. This synergistic effect is the cornerstone for achieving the dual goals of efficient treatment and safety guarantee.
2.6 Epidermal Temperature Regulation
It’s not blindly pursuing extremely low temperatures, but are committed to achieving precise intelligent temperature control. Its system can maintain the skin surface temperature stably within a safe and optimal range (such as -4℃to -30℃) based on set parameters. This precise temperature management avoids tissue frostbite caused by excessive or insufficient temperature fluctuations, ensuring the effectiveness and consistency of cooling therapy.
2.7 Prevention of Infection Risk
Although the air cooler itself does not have direct sterilization function, it creates a favorable environment for preventing postoperative infections through multiple indirect pathways. By reducing tissue edema, decreasing exudate, and inhibiting scab formation, it eliminates many potential infection hotbeds.
Meanwhile, a intact and undamaged epidermis itself is the most effective physical barrier against pathogenic microorganisms. Therefore, the air cooler significantly reduces the possibility of secondary infection by promoting a more ideal wound healing environment.

3.Unique Advantages of Coolplus
3.1 Excellent Collaborative Treatment Capability
Coolplus achieves a perfect integration of high-energy therapy and low pain experience. During the treatment process, it effectively suppresses the excitability of nerve endings by continuously delivering low-temperature airflow to the skin surface, thereby physiologically blocking the transmission of a large number of pain signals.
This not only greatly improves the comfort and tolerance of patients, allowing doctors to use more efficient treatment parameters, but also significantly shortens the single treatment time, bringing higher work efficiency and patient satisfaction to medical institutions.
3.2 Comprehensive Therapeutic Applicability
In order to cope with the differences in contour and skin sensitivity of different parts of the human body, this device innovatively features three different sizes of air vents. Large area air vents can quickly cover flat areas such as the back and abdomen, achieving efficient cooling; Medium air vents are suitable for cheeks, thighs, and other areas. Small and precise air vents can be safely and flexibly used for delicate areas such as the eye area and nose.
This design concept of targeted treatment ensures uniform and consistent cooling protection regardless of the size and shape of the treatment area, eliminating treatment blind spots and extending the effectiveness and safety of the equipment to the whole body.
3.3 Powerful high-speed cooling efficiency
Refrigeration efficiency is the core indicator for measuring the performance of air coolers. This product is equipped with a super cooling system composed of optimized compressors and environmentally friendly refrigerants, which can rapidly reduce the outlet temperature to an industry-leading level of -30℃. Ultra low temperature means stronger heat extraction ability and deeper skin protection depth.
In high-energy treatments such as laser or radiofrequency, this powerful cooling capacity can build a solid thermal buffer zone for the epidermis, minimizing the risk of thermal damage to the epidermis and allowing the target tissue of the dermis to absorb more energy, while pursuing maximum therapeutic effect while ensuring safety.
3.4 Intelligent and Convenient Operation Experience
We adopt an intelligent software system with humanized design, simplifying powerful functions into intuitive operations. The large color touch screen displays real-time temperature, air volume, and operating status. Doctors can easily call up customized cooling solutions such as pigment therapy, vascular therapy, etc. based on different treatment projects with just one click. The system also supports custom parameter combination storage and can record treatment data for subsequent analysis and case management.
This intelligent interactive design greatly reduces the operating threshold, shortens the learning curve of medical staff, and ensures the standardization and repeatability of the treatment process.
3.5 Durable and Stable Power Core
The reliability of equipment is directly related to the coherence and cost-effectiveness of clinical work. We have adopted a 1500Wh high-power silent air compressor from Germany as the core power source. Its excellent industrial design and manufacturing process ensure that the entire cooling system can achieve long-term uninterrupted stable operation in high load clinical environments.
This means that even in high-intensity work involving multiple consecutive surgeries, the equipment can provide continuous and stable cooling without any performance degradation, effectively avoiding treatment interruptions caused by equipment overheating protection or malfunction, and ensuring the smooth and professional operation of the clinic.
