Sunscreen is essential in protecting the skin from ultraviolet rays
But UV exposure affects the skin far deeper than the surface
When UV light reaches skin cells, it can create oxidative stress & DNA damage that influence both skin aging & skin cancer risk

Antioxidant defenses neutralize free radicals
DNA repair mechanisms correct UV injury
Immune responses monitor abnormal cells
Hormonal balance influences skin resilience & repair
