If you're after sun protection that's gentle on your skin, mineral sunscreen is your friend. Instead of absorbing UV rays like chemical formulas, it sits on the surface and reflects them. This makes it a brilliant option for sensitive or reactive skin types.

 

And if you've never been excited about putting on SPF before, that might be about to change. Korean mineral sunscreens have lightweight textures, skin-nourishing ingredients, and finishes that actually feel good to wear.

 

So, Glowies, let's get into what makes mineral sunscreen so great, and share some of our top picks to help you find your new daily go-to! 

What is a mineral sunscreen?

Mineral sunscreen, also known as mineral-based sunscreen, is a type of sunscreen that creates a physical barrier between your face and the sun. The active ingredients are typically zinc oxide and titanium dioxide, which sit on the surface of the skin to block UV rays.

 

Unlike chemical formulas, which absorb UV rays, mineral formulas work by deflecting UV away from the skin. This makes them a great choice of sunscreen for sensitive skin, as they don’t need to be absorbed to be effective so they’re less likely to trigger irritation.

Benefits of mineral sunscreen

Mineral sunscreens are well-loved because of their:

  • Gentle formulas. Mineral sunscreens are ideal not only for sensitive skin, but those struggling with redness, dryness, or even rosacea.
  • Immediate protection. Unlike chemical sunscreens, mineral SPF starts working as soon as it’s applied. You don’t have to wait until it has been fully absorbed by the skin.
  • Eco-friendliness. Mineral formulas use zinc oxide or titanium dioxide instead of UV-absorbing filters. This means they’re labeled as non-harmful sunscreen options for marine life.

How to choose the right mineral sunscreen

The best sunscreens are often labelled non-nano, meaning the mineral filter particles are larger. This ensures they remain on the surface of the skin rather than being absorbed, protecting sensitive skin from reactions. Check out our complete guide to sunscreens to learn more.

 

Additional ingredients can help calm irritation and support hydration. Look out for centella asiatica, panthenol, glycerin, and hyaluronic acid, which help soothe while supporting a healthy skin barrier.

 

Of course, you’ll also need to pay attention to SPF. For everyday wear, SPF 30 is generally considered the minimum, offering a good level of protection for day-to-day exposure. However, if you spend longer periods outdoors or are exposed to direct sunlight, SPF 50+ provides more comprehensive coverage.

 

Make sure your sunscreen is labelled broad-spectrum, so it protects against both UVA rays (which contribute to premature aging) and UVB rays (which cause sunburn). You can measure UVA protection through the PA rating system.

Final tips for optimal sun protection

Even the best mineral sunscreen won’t deliver full protection if it’s not used properly! Be sure to follow these tips to keep your skin looking glowing and gorgeous: 

  • Apply a generous amount (around two finger-lengths for the face) and give it a minute to settle before applying makeup. 
  • Make sure you don’t miss the ears, hairline, and around the nose.
  • Reapply consistently. Because mineral formulas sit on the skin, this is extra important if you’ve been outside, sweating, or touching your face throughout the day.

FAQs

What’s the difference between mineral and chemical sunscreen?

When comparing mineral vs chemical sunscreen, the difference comes down to how they protect your skin. Mineral sunscreens sit on the surface and deflect UV rays, while chemical sunscreens absorb UV rays into the skin. Mineral formulas are often preferred for sensitive skin. 

Is mineral sunscreen better?

The best sunscreen for you will depend on your skin type. Mineral formulas are often better for sensitive skin as they’re less likely to irritate; chemical sunscreens tend to feel lighter and more invisible on the skin, and hybrid options are great for combination skin.

Is Beauty of Joseon sunscreen mineral?

Most Beauty of Joseon sunscreens, including the popular Relief Sun, are chemical rather than mineral sunscreens. These are a great option if you have oilier skin and if you’re looking for an extra lightweight sunscreen that layers easily.

What is chemical-free sunscreen?

Chemical-free sunscreen is a term often used to describe mineral sunscreen, as it doesn’t rely on UV-absorbing chemical filters. Instead, it uses zinc oxide or titanium dioxide. 

What is reef-free sunscreen?

Reef-free sunscreen refers to formulas that avoid ingredients like oxybenzone and octinoxate, which have been linked to coral reef damage. Many mineral sunscreens fall into this category, though some chemical sunscreens do too.
