Mineral Based Sunscreen

Updated: Aug 16, 2018

Mineral based sunscreens are much better for the skin than chemical sunscreens, especially if you are prone to acne or other skin ailments.

If your skin is oily or prone to breakout, it can be tempting to skip sunscreen that has traditionally been seen to clog pores. Mineral based sunscreen contain microscopic particles that control the oil in the skin which can help prevent acne or worsen its condition.

Mineral based sunscreen have two active ingredients - zinc oxide and titanium dioxide. It is these compounds which are the only real way to prevent skin damage and premature ageing. They block the harmful effects of UVA and UVB by forming a barrier against the sun’s rays and reflect them. ⠀⠀⠀⠀⠀⠀⠀⠀⠀ Sunscreen using chemical blockers—typically have a combination of oxybenzone, avobenzone, octisalate, octocrylene, homosalate and/or octinoxate—which absorb UV radiation to dissipate it. ⠀⠀⠀⠀⠀⠀⠀⠀⠀ There are also two types of UV radiation: UVB, which is responsible for actual sunburns, and UVA rays, which penetrate deeper. Mineral-based, physical blockers protect against both. But since chemical blockers absorb the rays instead, this allows UVA to reach those deeper layers of your skin and do damage.

The zinc oxide gives you the most effective full spectrum protection against UVA and UVB rays. Any mineral based sunscreen that doesn’t contain this, is pointless. There must also be at least 7.5% titanium dioxide. This will provide the minimum SPF 30 with UVA protection that is required to prevent harm from free radicals which can cause sunburn and much worse.
