This video compares the levels of blue light emitted by portable electronic devices with sunlight, looking at whether light from these devices can be harmful. It discusses possible negative health effects, especially on children, and how even small amounts of light at night can affect children's brain development. Key findings on these risks are presented.

This video discusses ultraviolet radiation emitted by tanning devices and dermatological treatments, explaining how the body reacts to different ranges of the electromagnetic spectrum that the ozone layer allows to pass. It examines the types of UV-emitting lamps and devices, the importance of measuring their effective irradiance, and how to adjust doses according to skin phototype to minimise risks and optimise phototherapy. Key findings on the safe and effective use of these devices are presented.

This talks was part of the 1º International Syposiym ISD DErmajal held in 2024 . This talk on photoprotection covered various methods, including physical, topical, and systemic approaches, and their uses. It emphasized the role of photoprotection in preventing skin cancer and aging, supported by evidence. The discussion also addressed photoprotection tailored to different skin types, outlining specific sunscreen needs and concerns for each. Additionally, it explored how sunscreen affects vitamin D synthesis, including controversies and scientific evidence.
