## Summary

Wounds heal worse with age, and this review argues that zinc is part of the story. Zinc shortfalls are common in older adults, and the skin's ability to manage zinc shifts with age. The authors link this to cellular senescence (worn-out cells that stop dividing but keep causing inflammation) and slower repair. It's a narrative review, so it maps out the idea rather than proving that zinc supplements speed healing.

## Practical Takeaway

This review suggests zinc status is worth discussing with a doctor if skin healing seems slow.
