Beauty of Joseon Relief Sun Rice + Probiotics SPF50+: sunscreen guide and photoprotection research

What it is, and what makes the modern filter system different

Beauty of Joseon Relief Sun: Rice + Probiotics SPF50+ PA++++ is a daily hydrating organic sunscreen that feels like a lightweight moisturiser rather than a chalky sunblock. Formulated with 30% fermented rice extract and traditional Korean grain ferments, it shields the skin against both ultraviolet A (ageing) and ultraviolet B (burning) rays (official product page).

What sets this sunscreen apart is its use of modern, photostable chemical UV filters: Uvinul A Plus, Uvinul T 150, Tinosorb M, and Iscotrizinol (Uvasorb HEB). Unlike older first-generation filters (like oxybenzone or avobenzone) that often burn the eyes and degrade quickly in heat, these modern European and Asian filters offer exceptional photostability and zero chalkiness on South Asian skin tones. Additionally, it incorporates niacinamide (2%) to fight dullness and adenosine for skin smoothing, with no synthetic fragrance or drying denatured alcohol.

Who it suits, and how it behaves across skin types

• Dry and normal skin types: Acts as a 2-in-1 morning moisturiser and sunscreen, eliminating the need for a separate lotion underneath.
• Combination skin: Hydrates dry cheeks without clogging pores, though very oily T-zones may prefer setting with a light translucent powder.
• Sensitive complexions: Free from chemical sunscreen fragrance and drying alcohol, reducing the risk of contact redness or stinging.
• South Asian skin tones: Melts completely transparent within 30 seconds, leaving zero purple or ashy white cast.
• Underneath daily makeup: Creates a smooth, hydrated canvas that prevents foundation from flaking, clinging to dry patches or balling up.

Those with extremely oily skin who work long hours outdoors in peak summer may find the dewy finish slightly rich by afternoon. Read our guides on sun protection and tackling dark spots to understand comprehensive UV care.

What scientific research says about daily photoprotection and rice ferments

Preventing photoaging. Ultraviolet radiation is the predominant driver of premature facial wrinkles, pigmentation and loss of dermal elasticity. A landmark review published in Photodermatology, Photoimmunology & Photomedicine underscores that daily broad-spectrum sunscreen photoprotection is essential across all exposome environments. The authors concluded that daily use of broad-spectrum sunscreen containing antioxidant and anti-aging active ingredients can effectively reduce extrinsic aging (Krutmann et al., 2021). Daily compliance is key to reversing existing UV damage and protecting cellular DNA.

Rice-derived antioxidants for skin clarity. Rice has been a staple in Asian skincare for centuries due to its high concentration of vitamins, amino acids and ferulic acid. A randomized, single-blind clinical trial investigated the topical effects of rice bran antioxidants on human skin dullness. In the human clinical trial, the melanin index significantly decreased in the area where the FA cream was applied, and a questionnaire also subjectively confirmed the improvement of dark and yellowish dullness by FA cream (Tanaka et al., 2026). Incorporating 30% rice extract alongside broad-spectrum filters thus combines photoprotection with active antioxidant brightening.

How to use it in Bangladesh's climate for all-day protection

1. Skip heavy daytime cream: If you have normal or combination skin in summer, apply this directly after toner or light serum. Its rice moisturising base provides ample hydration.
2. Use the two-finger rule: Squeeze two full strips of cream along the length of your index and middle fingers (approximately 1.25 grams). This ensures you achieve the lab-tested SPF 50+ protection level.
3. Dot and blend: Spread evenly across forehead, cheeks, nose, chin, neck and earlobes. Allow 60 seconds to dry down to an invisible satin glow.
4. Reapply during sun exposure: If walking outside in midday Dhaka sun or sweating during transit, reapply every two hours to maintain coverage.
5. Cleanse thoroughly at night: While it does not contain pore-clogging waterproof waxes, using a gentle foaming cleanser in the evening ensures complete removal of daily urban grime.

During Bangladesh's intense summer and monsoon months, ambient humidity causes heavy mineral sunscreens to melt into chalky sweat streaks. Beauty of Joseon Relief Sun absorbs like a fluid lotion, preventing embarrassing white marks. In winter, its fermented nourishing base guards skin against dry, dusty afternoon winds.
