## Should you buy this?

The UK and EU Relief Sun: a dewy SPF50+ PA++++ cream with rice extract, niacinamide and modern UK/EU filters, at around £15. The brand says the Rice + Niacinamide name replaces Rice + Probiotics with no formula change. It is not the US-market Daily Relief Sunscreen.

Skip this if you need water resistance, a matte finish on very oily skin, or the US Daily Relief SPF 40 formula.

The UK and EU Relief Sun formula: a dewy protect layer that keeps skin reading as skin under a sheer base.

## The formula

Relief Sun is Beauty of Joseon’s international sunscreen, labelled SPF50+ PA++++ and built on four modern filters permitted in the UK and EU: Uvinul A Plus, ethylhexyl triazone, Tinosorb M and diethylhexyl butamido triazone. Rice extract — 30% of the formula, according to the brand — sits alongside rice germ extract, niacinamide and a group of ferment extracts.

The brand describes a creamy yet lightweight texture that dries down dewy without a white cast. Those are manufacturer descriptions; The Cast Index has not tested SPF, UVA protection or wear.

## Who it’s for

Normal, dry and combination skin that wants a comfortable, dewy SPF under a sheer base or on its own. Very oily skin may prefer a lighter fluid or a matte finish.

## What should you check before buying?

Check the name and the market. The UK page now calls it Rice + Niacinamide, while many retailers still list Rice + Probiotics, which the brand says is the same formula. The US-market Daily Relief Sunscreen SPF 40 is a different product with different filters. No water resistance is claimed.

## How to use it

1. Apply as the final step of morning skincare, before makeup
2. Use enough to cover face, neck and ears evenly
3. Reapply at least every two hours outdoors, and after swimming, sweating or towelling
4. Remove at night with your usual cleanser

## Questions and answers

### Is Relief Sun: Rice + Niacinamide the same as Rice + Probiotics?

Beauty of Joseon says yes: the product was renamed, and the formula, ingredients and size are unchanged. Retailer listings under either name refer to the same UK and EU sunscreen.

### Has Beauty of Joseon Relief Sun been discontinued?

Not in the UK or EU. It was withdrawn from the US market in early 2025, where the brand sells Daily Relief Sunscreen SPF 40 instead. UK and EU retailers continue to list Relief Sun.

### Does Beauty of Joseon Relief Sun contain probiotics?

The ingredient list contains ferment extracts, such as lactobacillus and saccharomyces ferments, rather than live cultures.
