Korean and Japanese Sunscreens: Why the Whole World Loves Them and Which One to Choose

If you've searched for a sunscreen in recent years, you've probably come across the terms Korean SPF or Japanese SPF. Across social media, online forums, and beauty magazines, they're often described as a true game changer in sun protection. But what actually makes them so special? And do they really live up to the hype?

These are some of the most frequently asked questions online. Let's take a closer look at the answers.

Why Are Korean and Japanese Sunscreens So Popular?

The reason is simple: most people don't dislike using SPF because of the protection itself, but because of how it feels on the skin.

Traditional sunscreens are often thick, greasy, leave a white cast, or pill under make-up. Korean and Japanese brands, on the other hand, have embraced a "skincare first" philosophy. SPF should protect the skin while also feeling like a high-quality skincare product. The result is lightweight textures that feel more like a serum, gel, or moisturiser than a traditional sunscreen.

Many users also appreciate that Asian SPF products often contain hydrating and soothing ingredients such as hyaluronic acid, panthenol, ceramides, and botanical extracts.

What's the Difference Between Korean and Japanese SPF?

Although these two categories are often grouped together, there are some differences.

Japanese sunscreens tend to focus on simplicity, minimalism, and exceptionally lightweight textures. They often suit sensitive skin and rely on well-established, thoroughly tested technologies.

Korean sunscreens are known for rapid innovation, modern UV filters, and a strong emphasis on active skincare ingredients. Many are designed to help achieve the coveted "glass skin" look – hydrated, radiant, and healthy-looking skin.

The good news? Both offer excellent sun protection.

What Do SPF50+ and PA++++ Mean?

This is one of the most common questions people ask.

SPF indicates protection against UVB rays, which are responsible for sunburn.

PA indicates protection against UVA rays, which contribute to premature skin ageing and the development of pigmentation.

The PA rating system uses plus signs:

• PA+ = Basic protection
• PA++ = Moderate protection
• PA+++ = High protection
• PA++++ = Extremely high UVA protection

Today, SPF50+ PA++++ is the standard you'll find on many of the best-selling Korean and Japanese sunscreens.

Are Korean SPF Products Suitable for Oily Skin?

Yes – and that's one of the main reasons they've gained such a loyal following.

Oily and combination skin often struggle with heavier European sunscreens. Korean SPF products are typically formulated to absorb quickly, feel lightweight, and leave little to no greasy shine. As a result, they're popular even among people who previously avoided sunscreen altogether.

Do They Leave a White Cast?

In most cases, no.

The absence of a noticeable white cast is one of the key reasons Asian sunscreens have become so popular worldwide. Modern UV filters make it possible to create lightweight, almost invisible formulas that look great on all skin tones.

Which Korean Sunscreens Are Considered Best-Sellers?

If we had to choose products that have achieved cult status, these would be among the most popular:

Beauty of Joseon Relief Sun Rice + Probiotics SPF50+ PA++++

One of the most famous Korean sunscreens available today. It combines high SPF50+ protection with a lightweight creamy texture and rice extract. It's particularly popular among people with dry, normal, and sensitive skin.

Beauty of Joseon Relief Sun Aqua Fresh Rice + B5 SPF50+ PA++++

A newer version of the bestselling line, offering an even lighter and fresher texture. It's an excellent choice for summer or for those with oilier skin types.

SKIN1004 Madagascar Centella Hyalu-Cica Water-Fit Sun Serum SPF50+ PA++++

A product that sits somewhere between a hydrating serum and a sunscreen. Thanks to Centella Asiatica and deeply hydrating ingredients, it's especially popular among people with dehydrated and sensitive skin.

COSRX Aloe Soothing Sun Cream SPF50+ PA+++

A long-standing bestseller among users looking for a comfortable sunscreen enriched with aloe vera. It not only protects the skin but also helps soothe and calm it.

Haruharu Wonder Black Rice Moisture Airyfit Sunscreen SPF50+ PA++++

A lightweight modern sunscreen featuring fermented black rice, combining high-level sun protection with daily skincare benefits.

How Should SPF Be Used Correctly?

This is where many people make mistakes.

Applying a small amount in the morning and assuming you're protected all day isn't enough. Dermatologists recommend using a sufficient amount of product and reapplying throughout the day if you're spending extended periods outdoors.

If you spend most of your day in an office, applying SPF50+ in the morning is usually sufficient. However, if you're at the beach, exercising outdoors, or spending hours in direct sunlight, regular reapplication is essential.

Is It Worth Switching to Korean or Japanese SPF?

If you've never enjoyed wearing sunscreen, the answer is often yes.

The comfortable skin feel, lightweight textures, high UVA and UVB protection, and the combination of sun protection with skincare are the reasons why Korean and Japanese sunscreens have become a global phenomenon.

And perhaps they'll help you discover that wearing SPF every day doesn't have to feel like an unpleasant chore – it can become one of the most enjoyable steps in your morning skincare routine.
