Hidden blood molecules show surprising anti-aging power

Scientists have identified new anti-aging compounds produced by a little-studied blood bacterium. These indole metabolites were able to reduce inflammation, oxidative stress, and collagen-damaging activity in skin cell cultures. Three of the compounds, including two never seen before, showed particularly strong effects. The findings hint at a surprising new source for future skin-rejuvenation therapies.
