Frequently Asked Questions
What SPF should I use every day?
The NHS recommends sunscreen with at least SPF 30, used alongside shade and protective clothing. Choose broad-spectrum UVA and UVB protection. Higher SPF can provide a greater margin when applied correctly, but no sunscreen gives complete protection.
How much sunscreen should I apply to my face?
Apply a generous, even layer to the face, ears and neck according to the product directions. A thin cosmetic layer may not deliver the labelled protection. Reapply during exposure and after swimming, sweating or towelling.
Is SPF 50 much better than SPF 30?
Both can provide high protection when applied correctly. SPF 50 filters more UVB than SPF 30 under test conditions, but application amount, missed areas and reapplication strongly affect real-world protection. Choose a broad-spectrum formula you will use generously.
Do I need sunscreen in the UK or on cloudy days?
UV can reach skin even when the weather feels cool or cloudy. Daily facial sunscreen is particularly useful when spending time outdoors, using photosensitising skincare or managing pigmentation. Check the UV index and use shade and clothing as well.
What is the difference between mineral and chemical sunscreen?
Mineral sunscreens use filters such as zinc oxide or titanium dioxide; other sunscreens use organic UV filters, and some formulas combine types. Both can provide effective protection when properly formulated and used. Choose based on verified UVA/UVB protection, texture, and tolerance.
Can make-up or moisturiser with SPF replace sunscreen?
Only if enough is applied evenly and reapplied as required, which is uncommon with make-up. A dedicated sunscreen makes adequate application easier. Treat SPF make-up as an additional layer rather than the only protection during meaningful exposure.
Do oral sun supplements replace sunscreen?
No. Supplements do not replace topical broad-spectrum sunscreen, shade, clothing or a hat. They must not be marketed as preventing sunburn or making prolonged exposure safe. Follow the supplement label and check suitability with a healthcare professional.
