Korean and Japanese sunscreens: why the whole world loves them and which one to choose?

If you’ve been looking for sunscreen in recent years, you’ve probably come across the term Korean SPF or Japanese SPF. On social media, discussion forums and in beauty magazines, they’re talked about as a “game changer” in protecting skin from the sun. But what actually makes them so special? And are they worth the hype?

These are exactly the questions people ask most often online. Let’s take a look at the answers.

Why are Korean and Japanese sunscreens so popular?

The reason is simple: most people don’t have an issue with using SPF because of the protection itself, but because of how it feels on the skin.

Traditional sunscreens tend to be thick, greasy, leave a white cast or pill under make-up. Korean and Japanese brands, on the other hand, introduced a “skincare first” philosophy – SPF should protect, but also behave like high-quality skincare. The result is lightweight textures that feel like a serum, gel or moisturiser.

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

What’s the difference between Korean and Japanese SPF?

Although the two categories are often lumped together, there are certain differences between them.

Japanese SPF tends to focus on simplicity, minimalism and very lightweight textures. It often suits more sensitive skin and emphasises long-proven technologies.

Korean SPF is known for rapid innovation, modern filters and an emphasis on active caring ingredients. It often aims for the hydrated, bright “glass skin” effect.

The good news? In both cases, you’ll get very high-quality sun protection.

What do SPF50+ and PA++++ mean?

This is one of the most common questions.

• SPF indicates protection against UVB radiation, which causes sunburn.
• PA indicates protection against UVA radiation, which speeds up skin ageing and the formation of pigmentation spots.

The PA scale is marked with plus signs:

• PA+ = basic protection
• PA++ = medium protection
• PA+++ = high protection
• PA++++ = very high UVA protection

That’s why you’ll now find the label SPF50+ PA++++ on most of the best-selling Korean and Japanese sunscreens.

Are Korean SPF creams suitable for oily skin?

Yes – and that’s exactly why they’ve gained so many fans.

Oily or combination skin often doesn’t tolerate thick European sunscreens well. Korean SPF products are usually formulated to absorb quickly, not weigh the skin down and not leave an unpleasant shine. That’s why they’re popular even among people who didn’t use SPF at all before.

Do they leave a white cast?

In most cases, no.

The lack of a white cast is one of the main reasons Asian sunscreens have become hugely popular. Modern UV filters make it possible to create lightweight, almost invisible formulas that look good on all skin tones.

Which Korean sunscreen is among the bestsellers?

If we had to pick products that have achieved cult status, these are the main ones:

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

One of the best-known Korean sunscreens today. It combines high SPF50+ protection with a lightweight creamy texture and rice extract. It’s loved by people with dry, normal and sensitive skin.

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

A newer version of the popular range, offering an even lighter, fresher texture. It works brilliantly in summer or for oilier skin types.

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

A product that sits on the border between a hydrating serum and a sunscreen. Thanks to centella asiatica and hydrating ingredients, it’s especially popular among people with dehydrated and sensitive skin.

COSRX Aloe Soothing Sun Cream SPF50+ PA+++

A long-time bestseller among users looking for a comfortable SPF with added aloe vera. It not only protects the skin, but also soothes it pleasantly.

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

A lightweight modern sunscreen with fermented black rice that combines high protection with everyday skincare.

How to use SPF correctly?

This is where people often make a mistake.

It’s not enough to apply a small amount in the morning and feel like you’re done. Dermatologists recommend using a sufficient amount of product and reapplying during the day if you’re outside for longer periods.

If you spend most of the day in the office, SPF50+ in the morning is usually enough. If you’re at the beach, doing sport or spending hours in direct sun, reapplication is essential.

Is it worth switching to Korean or Japanese SPF?

If you’ve disliked using SPF up to now, the answer is often yes.

That pleasant feel on the skin, lightweight textures, high UVA and UVB protection, and the combination of protection with skincare are the reasons Korean and Japanese sunscreens have become a global phenomenon.

And maybe thanks to them you’ll find that daily SPF doesn’t have to be an unpleasant chore, but one of the nicest steps in your morning skincare routine.
