Sun Protection

What does the research say?

Research shows that daily use of broad-spectrum sunscreen with SPF ≥ 30 can prevent photoaging and may reverse some signs of extrinsic aging. For example, a study found significant improvements in skin texture and pigmentation after 52 weeks of daily sunscreen use. Natural compounds like polyphenols and caffeine have also been shown to protect against UV-induced damage by reducing oxidative stress and promoting DNA repair, which may contribute to improved skin health and longevity [1] [7] [12] [14] .

Systemic absorption of certain sunscreen ingredients

Some organic UV filters, such as oxybenzone and octinoxate, can be absorbed into the bloodstream, though their long-term health effects are not yet fully understood [1] .

Allergic reactions to sunscreen ingredients

Certain sunscreen ingredients, like PABA and trolamine salicylate, have been linked to allergic reactions and skin irritation in some individuals [1] .

Environmental impact on coral reefs

Some sunscreen ingredients, particularly oxybenzone and octinoxate, have been shown to harm coral reefs, leading to environmental concerns [1] .
