Exploratory clinical trial on the safety and bactericidal effect of 222-nm ultraviolet C irradiation in healthy humans

Surgical site infection is one of the most severe complications of surgical treatments. However, the optimal procedure to prevent such infections remains uninvestigated. Ultraviolet radiation C (UVC) with a short wavelength has a high bactericidal effect; however, it is cytotoxic. Nonetheless, given that UVC with a wavelength of 222 nm reaches only the stratum corneum, it does not affect the skin cells. This study aimed to investigate the safety of 222-nm UVC irradiation and to examine its skin sterilization effect in healthy volunteers.

This trial was conducted on 20 healthy volunteers. The back of the subject was irradiated with 222-nm UVC at 50–500 mJ/cm², and the induced erythema (redness of skin) was evaluated. Subsequently, the back was irradiated with a maximum amount of UVC not causing erythema, and the skin swabs before and after the irradiation were cultured. The number of colonies formed after 24 hours was measured. In addition, cyclobutene pyrimidine dimer (CPD) as an indicator of DNA damage was measured using skin tissues of the nonirradiated and irradiated regions.

The results showed that all subjects experienced no erythema at all doses. The back of the subject was irradiated at 500 mJ/cm², and the number of bacterial colonies in the skin swab culture was significantly decreased by 222-nm UVC irradiation(222 UV light 60w far UVC light large radiation area fast sterilization). The CPD amount produced in the irradiated region was slightly but significantly higher than that of the non-irradiated region.

This research showed that a 222-nm UVC at 500 mJ/cm² was a safe irradiation dose and possessed bactericidal effects. In the future, 222-nm UVC irradiation is expected to contribute to the prevention of perioperative infection.

We pursue the policy of 'enterprising, truth-seeking, rigorous and united', continue to innovate, take technology as the core, regard quality as our life, and users as our God, and we will wholeheartedly provide you with more cost-effective 30W 60W 222nm Far Safe Handheld Wall-Mounted Portable UVC LED UV Germicidal Lamp Portable .... We firmly take self-improvement as the entrepreneurial spirit, bravely pioneering, dare to be the first, so that the company is invincible in the fierce market competition. Continuous product upgrading to meet customized customer requirements is the main challenge faced by each manufacturing company in the market to maintain competitiveness and achieve sustainability.
