Application of COB LED in the medical beauty industry

As a new type of light source, COB LED is gradually being used in medicine and playing a positive role as its biological effects are gradually recognized by people.

The biological effect of COB LED depends on different optical parameters, including wavelength, flow rate, power density, irradiation time, continuous wave or pulse wave, as well as treatment frequency, treatment interval, etc. Different wavelengths can reach different positions of skin tissue, and different wavelengths have different penetration depths in skin tissue. Generally speaking, the longer the wavelength, the stronger the penetration ability.

At the same time, light of different wavelengths can be absorbed by different color bases in tissue. In clinical practice, red light (630nm-700nm) is often used to treat deep skin tissue structures, such as sebaceous glands; blue light (400nm-470nm) is used for photodynamic therapy (PDT) to treat skin lesions located in the epidermis; if you want to reach the dermis of the skin, you need a longer wavelength, such as a wavelength of 660nm, which can reach the reticular layer of the dermis and act on the skin fibroblasts in the dermis. This is also one of the principles of LED light sources currently used for photorejuvenation and skin disease detection.

The application of LED in dermatology refers to the use of continuous intense pulsed light with low energy density for non-ablative skin rejuvenation treatment, which has become one of the main methods to improve skin aging. This technology can significantly improve skin wrinkles, rough texture, uneven pigmentation, large pores and other problems, and has been recognized by many technical professionals and beauty seekers. Studies have found that LED light from visible light to near-infrared can penetrate the skin epidermis and reach the dermis directly. Through photothermal and photochemical reactions, it promotes the regeneration and rearrangement of elastic fibers and collagen fibers, thereby reducing skin wrinkles and increasing elasticity.

In addition, LED light can detect skin diseases, promote the growth of epithelial cells after trauma, promote wound healing, and also has a good therapeutic effect on the healing of chronic ulcers in the lower limbs of diabetic patients. A series of studies have shown that LED has an anti-inflammatory effect in reducing inflammation. The use of LED light sources for irradiation of breast cancer and skin cancer patients before radiotherapy can reduce the side effects of radiotherapy.

In summary, COB LED, as a new type of light source, has gradually been used in the field of skin beauty medicine, and its high safety will have unlimited prospects in this application field.

Our customized COB LED power range covers 5W-3000W, and product features include high CRI value (CRI98+), multi-color array design (RGB/RGBW), multi-band combination, etc. We have rich experience in practical applications such as cross-polarized flash and non-polarized flash.
