If your skin quickly reacts with irritation to sun protection, it is worth taking a look at the filters. Mineral sun protection works with zinc oxide or titanium dioxide, and many formulations today can be applied so that hardly any white cast remains.
The key points in brief
- Mineral sun protection filters UV light with zinc oxide or titanium dioxide instead of chemical filters.
- In a review of allergies caused by UV filters, there was no report of a contact allergy to these two minerals.
- A review describes that tinted versions with iron oxides also filter visible light, which matters for skin prone to pigmentation spots.
- The amount is what counts: apply generously and reapply every 2 hours in the sun.
What does mineral mean?
Sunscreen, which we call sun protection, comes with two types of filters. Mineral filters are fine particles of zinc oxide or titanium dioxide. They intercept UV light before it gets deep into the skin.
A review describes it like this: zinc oxide broadly covers UVA and UVB, titanium dioxide protects particularly well against UVB. UVA makes the skin age, UVB causes sunburn. In the products further below, zinc oxide appears alone or together with titanium dioxide.
On the ingredient list, the two are called Zinc Oxide and Titanium Dioxide. You can recognise chemical filters by names such as Octocrylene, Homosalate or Butyl Methoxydibenzoylmethane. If only Zinc Oxide or Titanium Dioxide is listed as a filter, the sun protection is purely mineral.
Who does mineral sun protection suit?
After a peel or a laser treatment, the Face Shield Classic and the Face Shield Flex are part of our selection Skincare after treatments. The warning is clear on this: "Do not apply to damaged or injured skin." The place where you had the treatment will tell you when you can apply sun protection again.
If your skin gets irritated quickly, it is worth looking at the filters. A review collected reports of allergies caused by UV filters. The reports concerned chemical filters; none were found for zinc oxide and titanium dioxide.
If your skin is prone to pigmentation spots, a tinted sun protection is worth considering. A review concludes that sun protection without colour hardly filters visible light. The tint made of iron oxides intercepts part of it.
Whether a shade suits you is best seen on the jawline. Test it there once before you tint your whole face with it.
What is behind EnviroScreen?
EnviroScreen is what Colorescience calls its own technology in its sun protection. The mineral particles receive a fine coating of silicates and silicones. Added to this are antioxidants, that is, substances that neutralise free radicals, and iron oxides for the shade.
Free radicals are aggressive particles that form in the skin through sun exposure. You can read more about this in our guide to vitamin C. EnviroScreen is designed for four areas: UVA, UVB, blue light and infrared.
In brief: the coating was tested in the laboratory and on skin samples, not in people's everyday lives. In these tests, the researchers observed protection against UV light, blue light and infrared. The brand itself was involved in the study.
How to apply it correctly
This is how it works with the Face Shield Classic:
- Apply it in the morning as the last step, after your skincare.
- Take a generous amount and spread it over your face and neck. Skimping costs protection.
- Apply it at least 15 minutes before sun exposure.
- You can put make-up on top or leave it out entirely.
- In direct sun, reapply every 2 hours, especially after swimming or sweating.
For other products, follow what is stated on the packaging.
White film, tint, reapplying
In the past, mineral sun protection often left a white film. Today, many formulations use very fine particles that are hardly visible on the skin.
When choosing between transparent and tinted, a simple question helps: how should your skin look afterwards? If you want to see nothing, use a transparent sun protection such as the No-Show Mineral Sunscreen. If you also want an even-looking complexion, use a tinted version such as the Face Shield Classic or the Face Shield Flex.
A powder helps with reapplying. You apply the Brush-On Shield with the brush over your make-up, so nothing smudges. With the Face Shields, water-resistant means around 40 minutes, after which a new layer is due.

Frequently asked questions
Mineral or chemical sun protection: what is the difference?
The difference lies in the filter. Mineral sun protection works with fine particles of zinc oxide or titanium dioxide, on the ingredient list Zinc Oxide and Titanium Dioxide. You can recognise chemical filters by names such as Octocrylene, Homosalate or Butyl Methoxydibenzoylmethane. A review of allergies caused by UV filters found reports only for chemical filters, none for zinc oxide and titanium dioxide.
How much sun protection do I need for the face?
The warning states 2 milligrams per square centimetre of skin. In everyday life, this means: apply generously and do not skimp. If you use too little, the protection drops.
Can you use sunscreen as a moisturiser?
With the Face Shields, the sun protection goes on top of your skincare as the last step, not in its place. This is what the directions for use state, so your moisturiser stays underneath.
How do I apply the Face Shield Flex without streaks?
Work in thin layers: first the cheeks, then forehead, nose and chin. Let the first layer dry for 30 seconds and then apply a second. With a brush or sponge, the pigments spread most evenly.
Is there mineral sun protection that you cannot see?
Yes. The No-Show Mineral Sunscreen dries down transparent and filters only with zinc oxide. If you also want an even-looking complexion, choose a tinted version.
