Beauty of Joseon sunscreen is a line of popular Korean sun protection products led by its flagship Relief Sun: Rice + Probiotics SPF50+ PA++++, a lightweight chemical sunscreen that hydrates without leaving a white cast. It relies on modern organic UV filters combined with traditional hanbang ingredients to shield skin from daily sun damage while nurturing the skin barrier.
The brand has expanded its sun care line to include multiple formulas tailored to different skin types, finish preferences, and application environments. These include the Relief Sun Aqua-fresh for oily skin, the Matte Sun Stick: Mugwort + Camelia for easy touch-ups, and the Ginseng Moist Sun Serum. Understanding how these formulas behave, how their active UV filters function, and which option matches your specific skin concern ensures you achieve optimal broad-spectrum protection without causing breakouts, pilling, or shine.
How does Beauty of Joseon sunscreen protect and nourish skin?
In the global sun care market, Beauty of Joseon Relief Sun maintains its high standing by combining broad-spectrum ultraviolet protection with a skincare-first philosophy rooted in traditional Korean herbal medicine, known as hanbang. Where many legacy sunscreens prioritize high SPF at the expense of texture, leaving skin sticky or coated in a chalky film, the Beauty of Joseon formula behaves like a light hydrating serum.
The flagship sunscreen blends rice extract and grain-fermented probiotics to calm, illuminate, and reinforce the skin barrier during daily wear. This dual action elevates sunscreen from a required chore to a satisfying morning skincare step, encouraging consistent daily application, which remains the single most important factor in long-term sun defense and photoaging prevention.
Which UV filters does Beauty of Joseon sunscreen use?
The Beauty of Joseon Relief Sun provides SPF50+ and PA++++, denoting exceptionally high defense against both ultraviolet B (UVB) and ultraviolet A (UVA) radiation. The SPF rating measures defense against UVB rays responsible for sunburn, while the Japanese PA system evaluates protection against UVA rays, which penetrate deeply into the dermis to trigger collagen breakdown, hyperpigmentation, and long-term DNA damage.
The formula achieves this protection using four modern, photostable organic UV filters:
- Uvinul A Plus (Diethylamino Hydroxybenzoyl Hexyl Benzoate): Absorbs long-wave UVA radiation and maintains high stability without degrading quickly under intense sunlight.
- Uvinul T 150 (Ethylhexyl Triazine): Offers high absorption efficiency against UVB rays, protecting skin from surface burning.
- Tinosorb M (Methylene Bis-Benzotriazolyl Tetramethylbutylphenol): A hybrid organic filter that both absorbs and scatters UV rays, providing balanced protection across the full UVA and UVB spectrum.
- Iscotrizinol / Uvasorb HEB (Diethylhexyl Butamido Triazone): A hydrophobic filter offering durable UVB and UVA2 protection.
These modern filters absorb UV energy and convert it into low-level heat that safely dissipates from the skin surface. Unlike older physical filters like zinc oxide or coarse chemical filters like avobenzone, these advanced filters dissolve completely into the emulsion, eliminating white residue and minimizing eye sting.
What do rice extract, probiotics, and niacinamide do for your skin barrier?
The formula pairs UV filters with high-performance skincare actives.Oryza Sativa) alongside grain-fermented extracts. Rice water has been used in East Asian skincare for centuries due to its high concentration of amino acids, minerals, and vitamins B, C, and E. According to a 2026 review in the Journal of Cosmetic Dermatology, rice-derived ingredients exhibit antioxidant and anti-inflammatory properties, helping to soothe skin and combat free radical damage from environmental aggressors.
Grain-fermented probiotics, including Lactobacillus and Saccharomyces ferments, help balance the cutaneous microbiome. A healthy microbiome maintains optimal surface pH and protects against opportunistic pathogens. By reinforcing microbiome balance, this sunscreen reduces sensitivity and locks in hydration, making it an excellent choice for those with compromised skin barriers or conditions like rosacea.
Niacinamide supports ceramide synthesis, reduces transepidermal water loss, calms inflammatory redness, and regulates excess sebum, making the sunscreen a multi-functional daily treatment.
How does Beauty of Joseon sunscreen perform across different skin types and tones?
Because sunscreens behave differently depending on underlying skin chemistry, evaluating how Beauty of Joseon performs on distinct skin types ensures you select the right formula:
- Dry skin: The lotion-like texture delivers rich, lasting moisture. On dry or mature skin, it absorbs fully, smoothing fine lines and eliminating the need for a separate heavy morning moisturizer.
- Oily and combination skin: The original Relief Sun leaves a dewy finish that dry skin loves, but oily skin types in humid environments may find it overly shiny after a few hours. For those who prefer a weightless, non-greasy feel, the Relief Sun Aqua-fresh or Matte Sun Stick variants work better.
- Sensitive and reactive skin: Free from synthetic fragrance, essential oils, and harsh denatured alcohols, the formulation reduces the risk of contact dermatitis. The soothing probiotic complex helps prevent the flushing often triggered by harsher chemical sun filters.
- Acne-prone skin: The lightweight, non-comedogenic base does not clog pores. Niacinamide actively helps soothe existing inflammatory blemishes and fade post-acne dark marks over time.
- Dark skin tones: Because the UV filters are completely soluble, Relief Sun dries completely invisible, leaving no white cast, chalkiness, or gray sheen on deep skin tones.
How does Beauty of Joseon sunscreen wear under makeup?
Beauty of Joseon sunscreen is widely praised for its exceptional performance beneath cosmetics. It sets into a smooth, slightly tacky hydrating layer that acts as a natural priming base for liquid foundation, tinted moisturizer, or concealer.
To avoid pilling or sliding when layering makeup over sunscreen, follow these steps:
- Allow your morning hydration steps to absorb fully into the skin before applying sunscreen.
- Apply the sunscreen using outward gliding strokes, spreading it into a thin, smooth layer without aggressive rubbing.
- Wait 5 to 10 minutes for the sunscreen’s emulsifiers to form a uniform protective film over the face before applying liquid foundation.
Water-based foundations pair smoothly with Relief Sun, locking in a plump, dewy look throughout the day. If you use heavy silicone-based foundations, taking time to let the sunscreen fully settle prevents pilling along the jawline and around the nose.
What are the differences between Beauty of Joseon sunscreens?
The brand has expanded its sun protection lineup to suit diverse preferences and skin requirements:
- Relief Sun: Rice + Probiotics SPF50+ PA++++: The original cream-lotion formula. Best for normal, dry, sensitive, and combination skin types looking for a dewy finish and barrier repair.
- Relief Sun Aqua-fresh: Rice + B5 SPF50+ PA++++: A watery, fast-absorbing gel version. Formulated with rice seed water and panthenol (Vitamin B5), it leaves a fresh, weightless, natural-satin finish that suits oily and combination skin in hot or humid climates.
- Matte Sun Stick: Mugwort + Camelia SPF50+ PA++++: A solid, portable sun stick designed for touch-ups. Formulated with silica powder to absorb excess sebum along with mugwort and camellia oil, it provides a smooth, matte finish without disturbing underlying makeup.
- Ginseng Moist Sun Serum SPF50+ PA++++: A liquid serum sunscreen containing 30% ginseng extract and 2% niacinamide. It provides an ultra-light texture designed to revitalize dull skin while delivering broad-spectrum UV defense.

How should you apply Beauty of Joseon sunscreen for maximum coverage?
Applying the correct dose is essential for achieving the advertised SPF50+ and PA++++ protection levels. Standard dermatological testing requires an application density of 2 milligrams per square centimeter of skin, which translates to roughly 1/4 teaspoon (1.25 milliliters) for the face and neck.
- Cleanse and hydrate: Start with clean skin and apply lightweight hydrating serums.
- Measure the dosage: Dispense a full two-finger length strip of sunscreen along your index and middle fingers.
- Distribute evenly: Dot the product evenly across your forehead, cheeks, nose, chin, neck, and ears.
- Pat gently: Spread the cream gently across your skin in broad strokes, finishing with light patting to encourage absorption without causing friction.
- Allow to set: Wait 5 to 10 minutes before sun exposure or makeup application to allow the protective film to form fully.
Remember that sunscreen works best as part of a complete sun protection strategy that includes protective clothing, sunglasses, wide-brimmed hats, and seeking shade during peak ultraviolet hours.
How do you reapply Beauty of Joseon sunscreen throughout the day?
According to the American Academy of Dermatology (2025), sunscreen should be reapplied every two hours during extended sun exposure, or immediately after swimming or heavy sweating. Chemical and physical filters erode over time due to UV exposure, sebum production, and facial movement.
To reapply effectively depending on your daily setup:
- On bare skin: Apply a fresh quarter-teaspoon layer of Relief Sun directly onto clean hands and press gently into the skin every two hours.
- Over makeup: Use the Matte Sun Stick to glide light layers across the face, or gently press liquid Relief Sun over makeup using a clean cushion puff to prevent smudging base cosmetics.
- Antioxidant defense: Pairing your morning sunscreen with a Vitamin C or antioxidant serum boosts skin resilience against solar oxidative stress.
What are the drawbacks and who is Beauty of Joseon sunscreen not for?
Despite its broad versatility, Beauty of Joseon sunscreen has clear limitations you should keep in mind:
- Lack of water resistance: Relief Sun and Relief Sun Aqua-fresh are not water-resistant or sweat-proof. Swimming, intense exercise, or heavy sweating will wash away the UV film, leaving skin unprotected. For water sports or strenuous outdoor activities, use a dedicated water-resistant sport sunscreen.
- Shine on extremely oily skin: The original Relief Sun formula gives a distinct dewy finish. In hot, humid weather, extremely oily skin types may find it too shiny. Opt for the Aqua-fresh or Matte Sun Stick variants to maintain oil control.
- Sensitivity to fermented ingredients: While fermented probiotics benefit most skin types, individuals with extreme yeast sensitivities or fungal acne (Malassezia folliculitis) may react to fermented rice extracts.
What common sunscreen mistakes compromise your protection?
To get the full protection offered by Beauty of Joseon sunscreen, avoid these common mistakes:
- Under-applying product: Applying only a light dab of sunscreen cuts protection exponentially rather than linearly. Applying half the necessary amount drops an SPF50+ sunscreen down to roughly SPF7 to SPF10. Always use the two-finger measurement rule.
- Neglecting exposed areas: People frequently miss the eyelids, hairline, ears, and back of the neck. Extend sunscreen coverage across all exposed areas above the chest.
- Rushing makeup application: Applying foundation immediately after sunscreen drags the setting sunscreen matrix, disrupting coverage and causing pilling. Always give the formula 5 to 10 minutes to set.
- Relying on a single morning application: Assuming a single morning layer protects you through an entire afternoon outdoors is a common pitfall. Always carry a sun stick or portable lotion for periodic touch-ups.
