A mineral sunscreen is a sunscreen that uses minerals as its active ingredients. The main ingredients of mineral sunscreens are zinc oxide and titanium oxide. Also known as physical suncreens, these SPF's contain ingredients that sit on top of the skin and physically block the sun’s UV rays from the skin from the moment they’ve been applied. They’ve been proven to be effective and safe for us on all skin types, including children and people with sensitive skin.
They’re particularly good for anyone with pigmentation issues such as melasma as they block the sun from reaching these areas of the skin. It’s not as good for people with acne, oily skin or combination skin as it might contribute to breakouts because of the way it sits on the skin.
A usual problem with mineral sunscreen – especially for black skin – is the white cast it can leave on top of the skin. This can make darker skin look dull and ashy. There are mineral sunscreens available that don’t leave this film on the skin so it’s worth taking the time to find the one you love.In addition some mineral sunscreens have Titanium dioxide and zinc oxide, two naturally occurring minerals that when applied topically, they have the ability to block the sun's UVA and UVB radiation from being absorbed into your skin, meaning they are considered broad-spectrum.
