The Claim

Solar radiation induces oxidative stress in human skin through the generation of reactive oxidants, and nitric oxide counteracts this stress, establishing a dynamic equilibrium that is essential for maintaining skin homeostasis.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

How it works
1 study reviewed
In plain English

Sunlight can create harmful molecules in your skin, but your body naturally produces nitric oxide to balance them out—this balance keeps your skin healthy.

What the research says

1 study

  1. Study: Photo-induced nitric oxide modulation in human skin: Impacts of geographic location and seasonality on health and disease.

    Sunlight creates harmful molecules in the skin, but your body releases nitric oxide to balance them out and keep your skin healthy. When sunlight changes with seasons or location, this balance can get disrupted, leading to skin problems.
