There are many types of light source equipment used in the fields of photoelectronic beauty and medical treatment, and the emitted light wavelengths are also different. For example, IPL is a broad-spectrum light covering a range of wavelengths, while various lasers emit laser beams of specific single wavelengths. The photon cold gel used in conjunction should ideally have good transmittance for these commonly used treatment wavelengths, that is, it should have wide wavelength compatibility.
The core of wide wavelength compatibility lies in the gel medium itself having extremely low absorption and scattering within the target wavelength range. Pingchuang Medical's photon cold gel usually uses high-purity water as the main matrix. Water molecules themselves have a very low absorption coefficient in most commonly used treatment bands of visible light and near-infrared light (approximately in the range of 400nm to 1100nm, covering the wavelengths of IPL and most hair removal, skin rejuvenation, and spot removal lasers), and have a natural wide-band transmittance advantage.
In addition to water, other ingredients in the formula, such as thickeners (usually high molecular polymer), moisturizers, preservatives, etc., also need to ensure that there are no strong absorption peaks within the target wavelength range. The R&D team of Pingchuang Medical will consult the spectral characteristics of these excipients when selecting and using them, and will prioritize those known to have low absorption coefficients and stable optical properties in commonly used treatment bands. It avoids using substances that may cause significant absorption at specific wavelengths (especially critical treatment wavelengths).
The physical state of the gel also affects the wavelength compatibility. Any factor that may cause light scattering, such as bubbles, impurities, and uneven particles, will affect all wavelengths of light and reduce the transmittance. Pingchuang Medical produces bubble-free gel through vacuum degassing technology, selects high-purity raw materials, ensures the gel texture is even and delicate, and minimizes scattering effects to the maximum extent, thereby ensuring good transparency of the gel over a wide spectral range.
Generally, Pingchuang Medical's standard photon cold gel is designed to be colorless and transparent, which is also to ensure the best wavelength compatibility. Because any color means there is selective absorption of visible light at a specific wavelength. Colorless and transparent gel can ensure that various colors of light (corresponding to different wavelengths) can pass through with the minimum loss.
Gels with broad wavelength compatibility have significant advantages for beauty institutions using a variety of photoelectric equipment or brand merchants in need of a gel with strong versatility. There is no need to purchase and reserve different gels for different wavelength equipment, simplifying material management. Operators also do not need to change the gel when switching to different equipment or filters/handpieces, improving work efficiency. More importantly, it ensures that energy can be effectively transmitted whether using IPL or laser treatments of different wavelengths, ensuring the consistency and reliability of the treatment effect.
Pingchuang Medical carefully designs the formula matrix, auxiliary material selection, physical state control, and color appearance of its photon cold gel to make the product applicable to a wide range of wavelengths commonly used in photoelectric beauty. This broad wavelength compatibility is a reflection of the product's professionalism and versatility, meeting the needs of the vast majority of phototherapy applications and providing customers with convenient, efficient, and reliable solutions.
