What you need to know about mineral sunscreens and how they differ from chemical formulas

Curious about buying a mineral SPF but want to know more before making the switch? Here’s what you need to know…

There’s no denying that we all need to wear SPF every day to avoid signs of premature ageing and to reduce the risk of skin cancer – but the question is what type of sunscreen is best to use?

With extensive chemical and mineral SPF offerings to choose from, it can be hard to work out what formula is best for you.

In short, the main UV filters in mineral SPFs are titanium dioxide and zinc oxide, which sit on the skin’s surface and deflect the sun’s harmful rays. Mineral filters are also commonly known as physical sunscreens.

Chemical formulas work in a different way. They contain ingredients like octocrylene and avobenzone which are absorbed into the skin and then convert UV rays into heat energy instead.

So why opt for a mineral SPF? 

Some people like that mineral formulas don’t absorb into the skin. They are useful for people who have sensitive skin and can’t tolerate a product with an extensive synthetic ingredient list. 

Those with inflammatory skin conditions like psoriasis or eczema may also find a mineral SPF causes fewer flare-ups than a chemical one.

Other people like a zinc-based SPF formula because it’s currently the only recognised reef-safe UV filter available. This means that when you swim in the sea, it shouldn’t wash off the skin and have potentially detrimental effects on marine life or coral reefs.
