An effective daily sunscreen must meet two core requirements: broad-spectrum protection against UVA and UVB radiation, and a cosmetically elegant texture that integrates seamlessly into a skincare routine. Korean sunscreens, such as the Beauty of Joseon Relief Sun, have set a new standard in this field by combining advanced UV filters with nourishing ingredients. This article analyses the technical specifications and practical applications of Beauty of Joseon's popular sunscreen line to help you make an informed choice.
The decision for a sunscreen product should be based on objective parameters. The following criteria are relevant for daily use.
Modern chemical filters are the cornerstone of many Korean sunscreen formulations. Filters like Diethylamino Hydroxybenzoyl Hexyl Benzoate (Uvinul A Plus), Ethylhexyl Triazone (Uvinul T 150), or Drometrizole Trisiloxane (Mexoryl XL) offer stable and photostable protection across a broad UV spectrum. A key advantage of this filter generation is that it absorbs transparently into the skin without leaving a white cast, making it an excellent option for all skin tones.
The wearability of a sunscreen for daily use largely depends on its texture. A lightweight facial sunscreen should absorb quickly, feel non-sticky, and create a smooth base for subsequent makeup application. Formulations range from creamy lotions to light, watery fluids to cater to different skin types and preferences.
Beyond pure UV protection, many products contain active ingredients that provide additional skin benefits.
Protective performance is indicated by two metrics:
The Beauty of Joseon brand offers two main versions of its Relief Sun, tailored to different needs.
Why We Recommend It This version stands out for its balanced formulation, which combines intensive UV protection with the nourishing properties of 30% rice extract and fermented grain extracts. The creamy yet lightweight texture is similar to a moisturiser and is designed for daily use to hydrate and protect the skin simultaneously.
Pros
Who It's For This product is suitable for individuals with normal to dry or combination skin who prefer a moisturising effect and a natural, radiant finish. It is a solid choice for year-round daily use.
Why We Recommend It This version was developed for users who desire an even lighter, more watery consistency. The formula, with rice seed water and Panthenol (Vitamin B5), aims for refreshing hydration and skin-soothing benefits. According to clinical studies conducted by the manufacturer in Korea, the product has a cooling effect and can reduce sebum production, making it particularly appealing for warmer months or oilier skin types.
Pros
Who It's For Ideal for individuals with oily, combination, or sensitive skin. Also for those living in hot, humid climates or who prefer an extremely light, barely-there texture.

While tube formats are ideal for the daily routine, other solutions can be more practical for reapplying protection on the go. For compact and travel-friendly sunscreens, such as sun sticks, a look into the Travel Makeup category can reveal useful alternatives.
1. Is the Beauty of Joseon sunscreen suitable for sensitive skin? Both versions are formulated without added fragrances or essential oils, which reduces the potential for irritation. The Aqua-Fresh version with Panthenol is also designed for a soothing effect. Nevertheless, if you have known sensitive skin or allergies, a patch test should be performed on an inconspicuous area (e.g., the inner arm) before applying to the face.
2. Does the Beauty of Joseon Relief Sun leave a white cast? No, both products use modern chemical UV filters that absorb transparently into the skin. They are designed as a no-white-cast sunscreen and are therefore suitable for all skin tones, from very fair to very deep.
3. What do SPF 50+ and PA++++ mean? SPF 50+ indicates that the product offers very high protection against UVB radiation, which causes sunburn. The "+" signifies that the actual protection factor is above 50. PA++++ is the highest rating in the Japanese measurement system for UVA protection. It signals extremely high protection against UVA rays, which are responsible for accelerating skin ageing and other long-term skin damage.
