Abstract

Overview

The research explores the implications of UV and blue light exposure from various sources including the sun, artificial lighting, and electronic devices on skin conditions such as melanogenesis and oxidative stress.

Highlights

• LED technology widely employed in devices and lighting systems.
• Comparison of blue light exposure from artificial sources to sunlight in terms of skin pigmentation.
• Importance of understanding accumulative dose effects of blue light, particularly in sensitive individuals.

Findings

The study quantifies the percentages of blue light emitted by the sun and artificial sources such as LED devices and indoor lights. It discusses the effective irradiance of these sources in relation to pigmentation and oxidative stress. The findings suggest that while artificial sources emit less irradiance compared to the sun, their cumulative effect over time can still pose risks, particularly to those with sensitive skin types.

Conclusion

Although effective irradiance from artificial light and electronic devices is low relative to sunlight, the integration of all daily light exposures raises concerns about potential skin damage over long term exposure. Protective measures are particularly recommended for light-sensitive individuals and those with higher skin phototypes.
