Is mineral sunscreen better for sensitive skin?

What should you look for on the label?

Start with those three protection essentials, then narrow the choice to a formula labelled for sensitive skin. Avoid fragrance, parabens and oxybenzone if your skin is sensitive or prone to allergies. If sunscreen stings or burns, choose a product whose only sunscreen actives are zinc oxide, titanium dioxide or both, and avoid fragrance. An expensive brand is not necessary, which removes one fairly costly item from the label reading exercise.34

What is zinc oxide sunscreen?

Zinc oxide is a mineral sunscreen filter that protects against ultraviolet light, including UVA and UVB rays. Mineral sunscreen is also called physical sunscreen, but it works primarily by absorbing UV radiation, rather than simply bouncing sunlight away. Check the Active Ingredients section: some products combine zinc oxide with chemical filters. These are hybrid sunscreens, so seeing zinc oxide on the label does not mean the formula uses only mineral filters.25

Is titanium dioxide sunscreen good for sensitive skin?

Yes. Titanium dioxide is another mineral filter recommended for sensitive skin, either alone or alongside zinc oxide. Choose the finished sunscreen by its broad spectrum and SPF labelling, rather than by the mineral name alone. Those labels tell you about the product's protection; the ingredient name helps you choose the type of filter.23

Can zinc oxide sunscreen irritate skin?

A sunscreen containing zinc oxide can still irritate skin. The whole formula matters: fragrances, preservatives and other ingredients can cause reactions even when the sunscreen filters are mineral. Allergic contact dermatitis, an itchy rash caused by contact with an allergen, can appear where sunscreen was applied and sometimes spread elsewhere. Some reactions occur specifically where sunscreen and sunlight meet.6

If a sunscreen causes a rash, stop using that product and ask a dermatologist about identifying the trigger. Professional patch testing can identify an allergy; testing involving ultraviolet light can help investigate reactions linked to sunlight. Talk with your doctor before testing a sunscreen at home. A small area test over several days can help check for allergy, but a product that passes can still cause irritation. Avoid known allergens in replacement products, including mineral ones.6

How should you apply mineral sunscreen?

1. 1Apply sunscreen every day you will be outside, on skin not covered by clothing. Apply to dry skin 15 minutes before going outdoors.
2. 2Use at least one teaspoon for your face. Most adults need about one ounce to cover exposed skin, with more needed depending on body size. Include your ears, neck, tops of feet and exposed scalp.
3. 3Reapply approximately every two hours outdoors, and after swimming or sweating as directed on the bottle. For swimming, apply water resistant sunscreen at least half an hour before entering the water.
4. 4Check the water resistance duration on the label: it is either 40 or 80 minutes during swimming or sweating. No sunscreen is waterproof.
5. 5Use shade and protective clothing as well. Sunscreen alone cannot provide complete protection.

What if you dislike the texture or white cast?

Creams suit dry skin and facial use; gels suit oily skin and hairy areas. A tinted sunscreen that matches your skin tone can reduce white residue, so sun protection need not double as stage makeup. Check the protection essentials on tinted formulas too. If sunscreen feels unpleasant, clothing labelled with an ultraviolet protection factor, or UPF, provides another practical way to cover skin.234

Does the same advice apply to babies?

For babies younger than six months, prioritise keeping them out of the sun and using protective clothing. Ask a doctor before applying sunscreen at that age. For older children, use sunscreen as directed on the Drug Facts label.7
