Beauty of Joseon Relief Sun : Rice + Niacinamide

What is this product?

A Korean daily sunscreen from Beauty of Joseon's rice line, sold as a 50 mL cream tube on the brand's own store and filed as a UV protection functional cosmetic at SPF50+ and PA++++. Protection is organic only: four organic UV filters and no zinc oxide or titanium dioxide, which removes the usual source of white cast. Niacinamide is printed at 2 percent; rice extract, rice germ extract and three rice ferments carry printed levels in ppm and ppb. The brand prints SPF and PA test figures from 2021 and 2022, some on a Rice + Probiotics named version, and irritation, moisture and suitability tests whose footnotes do not name the product tested. There is no fragrance entry, no essential oil and no exfoliating acid. No lived use reports were collected.

What makes it different?

Within the brand's landed sunscreens this is the organic filter cream, where the tinted sibling relies on zinc oxide and titanium dioxide. Its label prints its own active levels, niacinamide at 2 percent and the rice entries in ppm and ppb, which makes the gap between the rice ferment copy and the list visible. The trade-off is test attribution: the brand's test footnotes either name an older Rice + Probiotics version or no product at all.

Did the ad claims hold up?

We checked 30 lines this product advertises against the ingredient list and public documents. One of them holds up. The rest are only partly right or have nothing behind them.
