Beauty of Joseon Sunscreen Dupe Guide: Compare Alternatives by Price, Finish & SPF
Beauty of Joseon sunscreen dupe options are compared by price, finish and SPF, with guidance on choosing a gel, serum or moisturizing cream.
Compare alternatives by price, finish, and label
- Choose Kiero Prime Sun Gel SPF 40+ when you want a light gel, and compare its $12.99 listed price with your Relief Sun checkout price; Kiero’s U.S. listing marked it sold out on October 12, 2026.
- Compare SKIN1004 Hyalu-Cica Water-Fit Sun Serum for a light, serum-like feel and a two-tube price of $16.15, or $8.08 per 50 ml.
- Choose Round Lab Birch Moisturizing UVLock Sunscreen when a light cream that also moisturizes is your priority; its U.S. listing showed $24.99 for 50 ml.
- Check SPF and the U.S. For a U.S. sunscreen, compare its SPF value as printed and look for the Broad Spectrum label.
A beauty of joseon sunscreen dupe search works best as an alternatives comparison: match price per 50 ml, finish, and printed SPF/PA wording before choosing.

How to compare Beauty of Joseon Relief Sun alternatives fairly
Start with the exact Relief Sun package and the seller you plan to use. Beauty of Joseon’s product FAQ says it renamed Relief Sun: Rice + Probiotics to Relief Sun: Rice + Niacinamide without changing the formula, ingredients, or size; both packages may appear during the label transition. Its official product page labels the sunscreen SPF 50+ PA++++, so shoppers can recognize the renamed product without mistaking it for a new formula.
Compare a single product against a single product, then convert the price to the same volume. Divide the listed price by the package milliliters, then multiply by 50 to get a 50 ml equivalent. For example, a 100 ml bundle listed at $16.15 works out to $8.08 per 50 ml: $16.15 ÷ 100 × 50. Use the same retailer type and price basis for each option, such as regular prices or current sale prices.
For example, if your full-checkout limit is $15, the captured SKIN1004 twin pack at $16.15 exceeds it even though its sale price equals $8.08 per 50 ml. Kiero’s listed $12.99 price for 50 ml falls below that budget, but the U.S. page marked it sold out on October 12, 2026, so the listed price did not make it a purchasable option that day.
In the FDA’s sunscreen guidance, SPF primarily indicates a product’s UVB protection, while broad-spectrum sunscreens also protect against UVA. Use the SPF value and the “Broad Spectrum” wording together when comparing U.S. sunscreen labels.
Isntree Hyaluronic Acid Watery Sun Gel: a second gel to price-check
Isntree is a useful candidate if you want another gel-format sunscreen with a hydration-focused daily description. The official Isntree Korean product listing showed the Hyaluronic Acid Watery Sun Gel in a 50 ml size for ₩13,500 on sale from ₩22,000 on October 12, 2026; Isntree’s homepage calls it a moisturizing daily sunscreen.
If you find an Isntree package sold for the U.S. market, compare its printed SPF and Broad Spectrum wording and its U.S. dollar price per 50 ml.
SKIN1004 Hyalu-Cica Water-Fit Sun Serum: a light daily layer
SKIN1004 fits shoppers who prefer a serum-like layer over a cream. SKIN1004’s Hyalu-Cica Water-Fit Sun Serum UV product page lists SPF 50 broad-spectrum coverage and describes an airy serum texture with a luminous finish and no white cast.
The SKIN1004 U.S. store listed a two-tube bundle containing 50 ml × 2 at $16.15 on sale, with a $19 regular price, in its official product collection. That equals $8.08 per 50 ml at the captured sale price or $9.50 per 50 ml at the listed regular price. The bundle is attractive on a per-volume basis when buying two tubes suits your budget and use; shoppers who want one tube can compare the single-item offer at their chosen retailer.
Round Lab Birch Juice Moisturizing Sunscreen: cream-like comfort
Round Lab fits shoppers who associate Relief Sun with a moisturizing daily feel and would like a lightweight cream. Round Lab’s Birch Moisturizing Sunscreen product page describes a lightweight cream sunscreen that hydrates and doubles as a moisturizer.
Beauty of Joseon’s Relief Sun product page describes a creamy-moisturizer feel with a lightweight, nonsticky finish. Among these candidates, Round Lab’s maker-described hydrating cream is the clearest alternative for someone prioritizing that moisturizer-forward texture.
Use the U.S. version’s own label when comparing it with Korean SPF/PA packages. Round Lab’s U.S. UVLock listing identifies the version as SPF 45 Broad Spectrum, and its U.S. shop listed the 50 ml tube at $24.99 on October 12, 2026. This makes it the higher-priced option among the U.S. listings with captured prices here, with a cream format for shoppers who value a moisturizing step.
Kiero Prime Sun Gel SPF 40+: choose it for a light gel
Kiero Prime Sun Gel SPF 40+ is our documented option for shoppers who want a light, fast-absorbing gel. It carries an SPF 40+/PA++++ label and contains chamomile, azulene, and panthenol. The U.S. package contains 50 ml, and the U.S. product listing showed a $12.99 regular price on October 12, 2026.
Prime Sun Gel SPF 40+
The listed price equals $12.99 per 50 ml, but the U.S. listing showed the product as sold out on October 12, 2026. It becomes a practical lower-price alternative only when the product is available and its current same-volume price is below the Relief Sun listing at the retailer you use. Its SPF 40+/PA++++ label also differs from Relief Sun’s SPF 50+ PA++++ label, so choose by the rating printed on the package as well as by finish.
The product ingredient list includes fragrance, so shoppers seeking fragrance-free sunscreen should choose a different formula. Its price per 50 ml is below Round Lab’s captured U.S. listing and above SKIN1004’s captured two-tube sale price per 50 ml.
