In addition, avoid using chemical sunscreens if possible. While physical sunscreens like zinc oxide or titanium dioxide work by reflecting UVA and UVB rays, chemical sunscreens such as Parsol 1789 absorb theses rays, causing skin to retain more heat, aggravating rosacea flare-ups. In terms of makeup, follow similar guidelines. Use fragrance-free formulas specifically targeted for sensitive skin. If any product causes a flare-up, discontinue use.

In general, patients with rosacea may find that it's easier to avoid the sun by remaining in shady areas or using protective coverings such as wide-brimmed hats. It may seem like a burden, but the extra precautions will help you avoid both flare-ups and sun damage.
