A clear comparison of mineral and chemical sunscreens, with guidance for sensitive, rosacea-prone skin.
The Nosacea Team
Evidence-based rosacea guidance
Sun exposure is one of the most common rosacea triggers. Choosing the right sunscreen can reduce redness and protect your skin long term.
Mineral Sunscreen Benefits
Mineral sunscreens use zinc oxide or titanium dioxide to reflect UV rays. They are often better tolerated because they sit on the skin rather than absorbing into it.
Chemical Sunscreen Considerations
Chemical sunscreens absorb UV rays. Some formulas can sting or irritate sensitive skin, especially during flare-ups.
