Frequently Asked Questions About Mineral Sunscreens & SPF
What is a mineral sunscreen and how does it work?
Mineral sunscreens use zinc oxide and/or titanium dioxide to create a physical barrier on the skin that reflects UV rays. Unlike chemical sunscreens, they work immediately and are less likely to cause irritation.
Is Zinc Oxide Good For Skin?
Zinc oxide is good for your skin. It is widely recognised for its protective and regenerative benefits. Zinc oxide in sunscreens acts as a physical block against the sun's rays. Zinc oxide has antibacterial and antioxidant benefits for the skin, enabling it to soothe irritated skin and reduce inflammation.
Which mineral sunscreen is best for sensitive or allergy-prone skin?
Look for fragrance-free, non-comedogenic mineral SPFs with minimal ingredients. These formulas reduce the risk of skin reactions and are ideal for rosacea, eczema, or sensitive skin.
