The Problem: The Struggle for a Comfortable Daily Sunscreen
Hello, we are THEMSELVES, your smart shopping curator. If you’ve spent any time exploring Korean skincare, you’ve probably come across the Beauty of Joseon Relief Sun: Rice + Probiotics SPF50+ PA++++. Finding a daily sunscreen that doesn’t feel heavy, greasy, or leave a chalky white cast can be an incredibly frustrating process for many consumers.
This specific product has become one of the most recognized Korean sunscreens worldwide—not simply because of social media popularity, but because its formula solves these exact problems by combining high UV protection with a lightweight, skincare-inspired texture.
So what actually makes this sunscreen stand out? Today, we are looking strictly at the official product information, ingredients, and cosmetic formulation to understand why it continues to be recommended by so many K-Beauty enthusiasts.
Deep Dive: Product Technology and Formulation
Beauty of Joseon is a Korean skincare brand inspired by traditional Korean herbal beauty philosophy while utilizing modern cosmetic science. Unlike many traditional sunscreens, the Relief Sun is formulated to feel more like a moisturizing cream than a heavy SPF barrier.
Key Ingredients Worth Knowing
- 30% Rice Extract: Rice has been used in Korean skincare traditions for generations. According to the brand, this extract provides hydration and contains naturally occurring vitamins, amino acids, and antioxidant compounds that help support the skin’s moisture barrier.
- Fermented Grain Extracts: Fermented skincare ingredients are commonly used in K-Beauty to help support hydration and soothe the skin. Rather than acting as sunscreen filters themselves, they are included to improve the overall skincare experience.
- Niacinamide: A well-known skincare ingredient frequently used in products designed to improve the appearance of uneven skin tone while supporting the skin barrier. Its inclusion makes this sunscreen function as a dual-purpose skincare step.
- Newer-Generation UV Filters: One reason the original Korean formula feels so lightweight is its use of newer-generation organic UV filters commonly found in Asian and European formulations. These filters are selected to provide broad-spectrum protection while maintaining a comfortable cosmetic finish.

Texture, Finish & Sensitivity
Based on the official product description and numerous editor reviews, the texture is creamy but lightweight, quick-absorbing, and non-sticky. It leaves no noticeable white cast on most skin tones and provides a natural, hydrated finish rather than a flat matte look. The brand states that the product is fragrance-free, alcohol-free, non-sensitizing in clinical testing, and tested for acne-prone skin.
(Note: As with any skincare product, individual reactions can vary, so patch testing is always recommended before full-face use.)
📌 The THEMSELVES U.S. Buyer’s Note
Here is a detail most reviews skip: due to FDA regulations on sunscreen filters, the version Beauty of Joseon officially sells in the United States is the Daily Relief Sunscreen SPF 40—a reformulation built around U.S.-approved filters while keeping the same rice-and-niacinamide skincare concept and lightweight, moisturizer-like feel.
Some third-party sellers list the imported Korean SPF50+ version, but buying the brand’s official U.S. listing is the most reliable way to avoid counterfeit products—a documented problem with viral K-Beauty sunscreens.
💡 Core Summary: Features & Considerations
- ✔ Skincare-Infused Protection: Combines reliable broad-spectrum protection with rice extract and niacinamide to simultaneously hydrate the skin.
- ✔ Cosmetically Elegant: Offers a lightweight, non-sticky cream texture that leaves a natural, dewy finish without disrupting makeup or leaving a white cast.
- ✔ Sensitive Skin Friendly: Expertly formulated without fragrance or alcohol, and tested for acne-prone skin.
- ➖ Consideration: If you have extremely oily skin and prefer an ultra-matte sunscreen, the inherently moisturizing and dewy finish of this formula may not be your first choice.
