How to Choose a Face Sunscreen: SPF 30 vs 50, Mineral vs Chemical and UVA Protection

The best face sunscreen is the one you will wear every day. This guide explains what the numbers and labels mean, how mineral and chemical filters differ, and how to pick a formula for your skin and routine.

What SPF and UVA ratings mean

SPF (sun protection factor) tells you how well a sunscreen protects against UVB, the rays that cause sunburn. It does not tell you about UVA, which reaches deeper into the skin and is linked with premature ageing. For UVA, look for a broad spectrum label. In the UK and Europe that is the UVA logo (the letters UVA in a circle), often alongside a star rating. Asian sunscreens show a PA rating, such as PA++++, where more plus signs mean stronger UVA protection.

SPF 30 or SPF 50?

SPF 30 filters out roughly 97% of UVB and SPF 50 roughly 98%, so the step up is small. SPF 30 is a sensible everyday choice, and SPF 50 gives a little more margin for long days outdoors, holidays and fair or sun-sensitive skin. Neither replaces shade, clothing and a hat, and both only work if you apply enough and reapply.

Mineral, chemical or hybrid?

  • Mineral (physical) sunscreens use zinc oxide or titanium dioxide, which sit on the skin and reflect and scatter UV. Many people with sensitive skin prefer them, though tolerance is individual, and some leave a white cast.
  • Chemical sunscreens use filters that absorb UV. They tend to feel lighter and sheerer on the skin, which makes them popular for daily wear under make-up.
  • Hybrid formulas combine both.

All three can give broad-spectrum protection when used correctly, so choose on feel, finish and skin tolerance.

How to apply face sunscreen

  • Apply it as the last step of your morning skincare, before make-up.
  • Use a generous amount. A commonly suggested guide is two finger-lengths of product for the face and neck.
  • Reapply every two hours when outdoors, and straight after swimming, sweating or towel drying.
  • Wear it year-round. UVA is present all year and can pass through glass.

Sunscreen is one part of sun safety. If you notice a mole or spot that is new, changing or bleeding, have it checked by your GP.

Face sunscreen: frequently asked questions

What is the difference between mineral and chemical sunscreen?

Mineral sunscreens use zinc oxide or titanium dioxide to reflect and scatter UV rays, while chemical sunscreens use filters that absorb UV. Hybrid formulas combine both. All can give broad-spectrum protection when used correctly.

Is SPF 50 better than SPF 30?

SPF 50 filters slightly more UVB than SPF 30 and is a good choice for long days outdoors. What matters most is applying enough and reapplying regularly.

Do I need to wear SPF in winter or indoors?

UVA rays are present all year and can pass through glass, so many people wear a daily SPF year-round, as the last step of the morning routine.

How often should I reapply sunscreen?

Reapply every two hours when outdoors, and straight after swimming, sweating or towel drying.

What does PA++++ mean on a sunscreen?

PA is the Asian rating system for UVA protection. More plus signs mean stronger UVA protection, and PA++++ is the highest level.

Is there a tinted sunscreen?

Yes. MZ Skin Tint & Protect Skin Perfecting SPF 30 Tinted Cream is a tinted moisturiser with SPF 30 UVA/UVB protection. It contains fragrance, so patch test if you are sensitive.

How do I choose a dermatologist-recommended sunscreen?

There is no official list, so choose by label: broad spectrum (the UVA logo or a PA rating), SPF 30 or 50, and a texture you will wear every day. If you have a skin condition, ask your own dermatologist. Our doctor-led edit lists brands created by doctors.
