Abstract:
The skin barrier and its endogenous protective mechanisms cope daily with exogenous stressors, of which ultraviolet radiation (UVR) poses an imminent danger. Although the skin is able to reduce the potential damage, there is a need for comprehensive strategies for protection. This is particularly important when developing pharmacological approaches to protect against photocarcinogenesis. Activation of NRF2 has the potential to provide comprehensive and long-lasting protection due to the upregulation of numerous cytoprotective downstream effector proteins that can counteract the damaging effects of UVR. This is also applicable to photodermatosis conditions that exacerbate the damage caused by UVR. This review describes the alterations caused by UVR in normal skin and photosensitive disorders, and provides evidence to support the development of NRF2 activators as pharmacological treatments. Key natural and synthetic activators with photoprotective properties are summarized. Lastly, the gap in knowledge in research associated with photodermatosis conditions is highlighted.
Insights
Activating the NRF2 pathway offers comprehensive protection against skin damage from ultraviolet radiation (UVR). This approach shows promise for treating photodermatosis and preventing photocarcinogenesis.
Area of Science:
- Dermatology
- Molecular Biology
- Biochemistry
Background:
- The skin barrier is constantly challenged by environmental stressors, notably ultraviolet radiation (UVR).
- While the skin possesses protective mechanisms, comprehensive strategies are needed to mitigate UVR-induced damage, especially for photocarcinogenesis and photodermatosis.
- The NRF2 pathway's activation is a promising avenue for enhancing cellular defense against UVR.
Purpose of the Study:
- To review the detrimental effects of UVR on normal skin and in photodermatosis.
- To explore the potential of NRF2 activators as a pharmacological strategy for photoprotection.
- To summarize existing natural and synthetic NRF2 activators with photoprotective capabilities.
Main Methods:
- Literature review of UVR-induced skin alterations.
- Analysis of NRF2 pathway's role in cellular protection.
- Compilation of data on NRF2 activators and their photoprotective properties.
Main Results:
- UVR causes significant damage to skin cells, which is exacerbated in photodermatosis.
- NRF2 activation upregulates cytoprotective proteins, counteracting UVR-induced damage effectively.
- Several natural and synthetic compounds demonstrate potential as NRF2-activating photoprotective agents.
Conclusions:
- NRF2 activation presents a robust strategy for broad and sustained photoprotection.
- Developing NRF2 activators could offer novel therapeutic options for photodermatosis and prevention of UVR-related skin damage.
- Further research is needed to address knowledge gaps concerning NRF2 activation in photodermatosis.

Nucleotide Excision Repair
Cells are regularly exposed to mutagens—factors in the environment that can damage DNA and generate mutations. UV radiation is one of the most common mutagens and is estimated to introduce a significant number of changes in DNA. These include bends or kinks in the structure, which can block DNA replication or transcription. If these errors are not fixed, the damage can cause mutations, which in turn can result in cancer or disease depending on which sequences are...
