In plain English: If regular sunscreen stings your skin, a zinc oxide sunscreen usually won’t. It’s a mineral that blocks the sun, and modern tinted versions don’t leave a white cast.
Zinc oxide is one of only two mineral (inorganic) UV filters, alongside titanium dioxide. It protects across a broad range of UVB and UVA wavelengths, including long UVA rays that drive tanning, which few single filters cover so well.
What it does
- Blocks UVA and UVB by absorbing and scattering ultraviolet light.
- Soothes, which is why it is also used in nappy rash and calamine creams.
- Rarely irritates, making it ideal for sensitive and post-treatment skin.
How to use it
Apply mineral sunscreen as the last morning step, two finger-lengths for face and neck. Reapply every two to three hours outdoors. Read Sunscreen for Indian Summers for the full guide.
Who should use it
Sensitive, reactive or rosacea-prone skin, anyone recovering from a procedure, and anyone whose skin stings with chemical filters.
Frequently asked questions
Is zinc oxide better than chemical sunscreen?
Neither is universally better. Zinc oxide is gentle and broad-spectrum; modern chemical filters are lighter and invisible. Many excellent sunscreens combine both.
Why does mineral sunscreen look white on me?
Zinc oxide particles reflect visible light, which shows up as a white or grey cast on medium and deep skin. Tinted formulas with iron oxides blend in and add visible-light protection.
