What’s the difference between mineral and chemical SPF?

Skincare

There are two main types of sunscreen out there, so here’s what you need to know when shopping:

Chemical (also known as organic or synthetic) sunscreens

These are the most commonly used sunscreens and work by absorbing UV light and releasing them back into the atmosphere as heat – so your skin doesn’t hold onto the heat.

Chemical sunscreens absorb into the skin and need to be applied 20 minutes before sun exposure. They tend to have a thinner and more lightweight texture and spread more easily on the skin.

However, due to the chemical formula, this type of sunscreens gets ‘used’ up quickly when in direct sun, so needs to be re-applied regularly.

Mineral sunscreen can often leave a white cast on the skin and therefore aren’t the best at being inclusive for all skin tones, plus larger amounts are required to achieve adequate protection.

It needs to be applied regularly throughout the day for effective skin protection.

Mineral (also known as physical) sunscreen works by scattering or reflecting UV light (a bit like a mirror would).

They provide protection from the sun immediately after application and tend to last longer in the sun. However, be aware that they wash off with sweat and water.
