The Claim
Sunlight exposure triggers photolysis of nitric oxide reserves in human skin, leading to the release of bioactive nitric oxide that counteracts reactive oxidants and helps maintain a healthy redox balance, a mechanism that is disrupted in chronic inflammatory skin diseases.
What the research says
Roughly balanced
Support and challenge are close. The picture may shift as more studies come in.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
When your skin is exposed to sunlight, it releases a natural substance called nitric oxide that helps calm down harmful molecules in your skin and keeps things balanced — but this doesn't work right if you have long-term skin inflammation.

Sunlight exposure triggers photolysis of nitric oxide reserves in human skin, releasing bioactive nitric oxide that counteracts reactive oxidants and helps maintain a healthy redox balance, a mechanism disrupted in chronic inflammatory skin diseases.
What the research says
1 studySunlight hitting your skin releases a helpful molecule called nitric oxide that fights harmful chemicals and keeps your skin healthy. When people have chronic skin problems like eczema or psoriasis, this system doesn’t work right, and less sunlight (like in winter) makes it worse.
