Whether the light energy in laser or IPL therapy can be precisely and efficiently applied to the target tissue (such as hair follicles, pigment spots, or blood vessels) is the key to the success or failure of the treatment. As a medium for the transmission of light energy from the device probe to the skin, the quality of the photon cold gel directly affects the conduction efficiency and accuracy of light energy.
The primary characteristic of the professional-grade photon cold gel is the ultimate "optical purity." This means that the gel itself has an extremely high transmittance for the specific wavelength of light used in the treatment, with very low absorption and scattering. Pingchuang Medical selects ultra-pure water and high molecular materials with excellent spectral properties as the matrix, strictly controlling the purity of the raw materials to avoid any impurities or pigments that may absorb the treatment light. At the same time, advanced vacuum degassing technology is used to completely remove the tiny bubbles in the gel. Bubbles will severely scatter light, not only reducing the energy density but also causing the light beam to disperse, affecting the accuracy of the action. Optical purity gel ensures that light energy is transmitted with the minimum loss and in the closest state to the original light beam quality.
Secondly, professional-grade photon cold gel needs to provide a stable and uniform optical coupling interface. The skin surface is not an ideal optical plane and has irregularities and air. Air will strongly reflect light, leading to significant energy loss. The photon cold gel from Pingchuang Medical has been optimized for viscosity and rheological properties, which can uniformly fill the tiny gaps on the skin surface and form a tight, gapless contact with the skin and probe surfaces. This stable and uniform coupling layer ensures that light energy can smoothly enter the skin from the probe, avoiding energy fluctuations and uneven distribution due to poor contact, and ensuring the stability and reproducibility of energy transmission.
Thirdly, professional-grade photon cold gel also needs to have good "refractive index matching". Ideally, the refractive index of the gel should be as close as possible between the probe optical window (such as sapphire) and the stratum corneum of the skin, to further reduce the Fresnel reflection loss at the interface of different media. Pingchuang Medical takes this into account in the formula design, selecting an appropriate raw material system to optimize the refractive index. Although complete matching is difficult to achieve, it strives to maximize the coupling efficiency of light energy.
Fourthly, the physical and chemical properties of professional-grade photon cold gel must be stable. During the treatment process, the gel cannot change its properties due to the heat or light of the equipment (such as becoming thinner, changing color, or degrading), nor can it have an adverse reaction with the probe material or skin. Pingchuang Medical selects stable raw materials and ensures the gel maintains its excellent optical and physical properties throughout the treatment process through strict quality control, providing a guarantee for the continuous and accurate transmission of light energy.
Why can't ordinary gels be used arbitrarily? Because they may not meet the strict requirements of phototherapy in terms of optical purity (containing impurities and bubbles), transmittance (absorbing specific wavelengths), viscosity (difficulty in forming a stable coupling layer), and safety (may contain irritant ingredients), leading to energy loss, poor effects, and even safety risks.
