A beauty journalist recently shared how Beauty of Joseon's Relief Sun: Rice + Probiotics SPF50+ transformed their daily skincare routine. After testing the formula for six months, the reviewer found it outperformed several luxury alternatives that cost twice as much.

The 30% rice extract formula driving the K-beauty glow

The popularity of the Beauty of Joseon Relief Sun:Rice + Probiotics SPF50+ is rooted in its "skincare-first" approach, a major trend in the Korean beauty market.. Rather than acting as a heavy, standalone shield, the product functions as a hybrid between a serum and a moisturizer. As the journalist reported, the formula is centered around 30% rice extract and fermented grain extracts, which are traditional Korean ingredients used to replenish and hydrate the skin.

Beyond the rice, the inclusion of glycerin and niacinamide provides a multi-functional benefit. While glycerin acts as a moisture-absorbing sponge,niacinamide helps regulate oil production and supports the skin's natural ceramide production. This combination allows the product to work for various skin types, including combination skin, by providing a plump, hydrated finish without the heavy feeling of traditional sunscreens.

Why the non-water-resistant formula needs reapplication after swimming

While the texture is praised for being lightweight and leaving no white cast, there is a significant practical caveat for active users. The Beauty of Joseon sunscreen is not water-resistant, meaning it requires frequent reapplication during activities like swimming, running, or heavy sweating. The reviewer noted that during a summer involving long runs and pool time, they had to be diligent about reapplying to maintain protection.

This lack of water resistance also means the product is not inherently mattifying. For those with oily skin types who prefer a shine-free look , the report suggests that the formula might require a setting powder to prevent a greasy appearance throughout the day.

Beauty of Joseon’s strategy of formula over elaborate packaging

The accessibility of this product is no accident; it is a result of a specific manufacturing philosophy. According to the report, Beauty of Joseon follows a popular Korean model that prioritizes high-quality formulas and large-scale production over expensive, overly elaborate packaging. this allows the brand to offer sophisticated ingredients—like mugwort and green tea extract—at a price point that rivals much more expensive Western brands.

This "no-frills" approach to aesthetics has allowed the brand to build a cult following on social media, where consumers increasingly value ingredient transparency and efficacy over the prestige of a heavy glass jar or gold-embossed box.

Choosing between the OG Relief Sun and the panthenol alternative

For consumers who find the original Relief Sun formula too rich, the brand offers a sister product designed with a more watery consistency. This alternative includes panthenol to help soothe the skin barrier, specifically targeting those with oily or combination skin. However, some details regarding the full lineup remain slightly unclear in the current reporting.

While the source mentions a product featuring 15 different shades and a luminous finish with 12-hour oil control, it is not explicitly clear if this is a separate tinted version or part of the panthenol-based line. Additionally, while the brand offers various options, it remains to be seen how the long-term efficacy of these lighter formulas compares to the original version during extreme weather or high-intensity sun exposure.
