Isntree vs. Beauty of Joseon Relief Sun
The two most talked-about K-beauty sunscreens, priced identically, both fragrance-free. A watery hyaluronic gel against a broader antioxidant-and-niacinamide rice formula.

|---|---|---|
| Price | $19.00 | $19.00 |

| Price checked | 9/12/2026 | 9/12/2026 |
Both are arguably the most-discussed K-beauty sunscreens in Western markets, chemical filters, fragrance-free, and priced identically, so the real question is what each formula actually adds beyond sun protection.
Why compare these two specifically
These are the two sunscreens most frequently cited as K-beauty's breakout hits, at an identical price and both fragrance-free, which makes formula depth the real deciding factor rather than cost or filter-sensitivity concerns.
Price per milliliter
Isntree runs $0.38 per milliliter ($19.00 for 50mL). Beauty of Joseon runs $0.38 per milliliter ($19.00 for 50mL). Identical.
Watery hydration vs. broader antioxidant blend
Isntree's confirmed key ingredients are hyaluronic acid and centella asiatica, a lightweight, watery-gel texture, though the brand's own copy also claims a broader formula including niacinamide and ceramide NP. Beauty of Joseon's confirmed list runs longer: rice extract, probiotics extract, niacinamide, adenosine, green tea extract, ginseng root extract, and tocopherol, a more layered antioxidant-and-tone formula.
A real texture trade-off on Isntree
Isntree's watery-gel texture means some report needing a setting powder to fully cut shine. Beauty of Joseon is widely reported to leave no white cast and has a longer track record as YesStyle's bestselling sunscreen.
Our take
At an identical price, Beauty of Joseon's confirmed ingredient list is the more built-out formula, layering in adenosine, ginseng, and green tea alongside niacinamide. Isntree remains the lighter, more watery texture if that specifically matters to you, though be ready to set it with powder if shine control is a priority.
Isntree Hyaluronic Acid Watery Sun Gel: $0.38/mL. A very lightweight, watery-gel texture, may need a setting powder for full shine control.
Beauty of Joseon Relief Sun: Rice + Niacinamide: $0.38/mL. A more layered antioxidant-and-tone formula with a longer bestseller track record and no reported white cast.
