Round Lab Birch Juice Moisturizing Tone-up Sun Cream SPF50+ PA++++

Round Lab's Birch Juice Moisturizing Tone-up Sun Cream (SPF50+ PA++++) is a hybrid organic/inorganic sunscreen, per the brand's own Olive Young Q&A answer, that adds tone-up pigments (Titanium Dioxide plus iron oxides) not present in the plain Birch Juice Moisturizing Sun Cream. Its declared UV-filter set differs from the plain Birch Juice Moisturizing Sun Cream: the two share Uvinul A Plus and Uvinul T150, but this tone-up variant swaps Tinosorb M and Uvasorb HEB for Titanium Dioxide and Tinosorb S (Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine). Brand-reported lab test values (distinct from the rounded label) show this variant testing to a higher raw SPF than the plain sun cream (SPF 63.3±6.3 vs. SPF 55.0±8.5), though both round to the same SPF50+ PA++++ label under Korea's testing convention.

Specifications

Is it OK for sensitive skin?

Declared facts only, not a suitability verdict: no fragrance listed; no labeled fragrance allergens declared; no denatured alcohol listed. No irritation-related fact here implies suitability for any skin type.

How much of the key actives does it contain?

Niacinamide: rank 10 of 62; Betula Platyphylla Japonica Juice (named in the product title): rank 15 of 62; Panthenol: rank 24 of 62; Adenosine: rank 50 of 62.

Can I buy it outside Korea?

International shipping: YesStyle; Sold in Korea only: Olive Young Korea; Shipping scope unverified: Round Lab official site (roundlab.co.kr); Global price: US$19.60 (YesStyle, sale price; list US$28.00).

Is the Korean version of Round Lab's Birch Juice Tone-up Sun Cream different from the export version?

No reformulation found — YesStyle's export listing of "Birch Juice Moisturizing Tone Up Sunscreen" (50ml) matches the Korea listing's name, volume, and SPF50+ PA++++ rating, and describes the same Inje-birch-sap, titanium-dioxide-tone-up formula (checked 2026-09-04). Unlike the plain Birch Juice Moisturizing Sun Cream — which has a separately-named, FDA-monograph-reformulated US product ("UV Lock SPF45") sold on Amazon/Target/Ulta — no distinctly renamed US version of this tone-up product was found on those retailers. YesStyle's own listing shows only a partial "key ingredients" summary rather than a full INCI disclosure, so an exact ingredient-by-ingredient match could not be independently confirmed from that listing alone.

Has this sunscreen passed non-comedogenic or acne-safe testing?

No — Round Lab's own Olive Young Q&A answer states no separate non-comedogenic or acne-prone-skin-suitability certification was conducted, though the product passed Germany's Dermatest for a low-irritation formulation (brand-stated, 2025-11-27, checked 2026-09-04).

Is the SPF/PA the same as the plain (non-tone-up) Birch Juice Moisturizing Sun Cream?

Both are labeled SPF50+ PA++++, but the brand's own Olive Young Q&A answer gives different underlying lab-test values: the plain Birch Juice Moisturizing Sun Cream tested SPF 55.0±8.5 / PA 19.80±3.30, while this tone-up variant tested SPF 63.3±6.3 / PA 19.9±3.6 (brand-stated, 2026-03-05, checked 2026-09-04) — both round to the same label rating under Korea's testing convention.

Is this a mineral (inorganic-only) sunscreen?

No — Round Lab's own Olive Young Q&A answer describes it as a hybrid organic/inorganic UV filter sunscreen (brand-stated, 2026-06-01, checked 2026-09-04), consistent with the Korea listing's ingredient disclosure, which lists Titanium Dioxide alongside three organic filters: Diethylamino Hydroxybenzoyl Hexyl Benzoate (Uvinul A Plus), Ethylhexyl Triazone (Uvinul T150), and Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine (Tinosorb S).

Is it vegan?

No vegan certification mark was found on the Olive Young KR listing, Round Lab's own store, or the YesStyle export listing, checked 2026-09-04.
