TIRTIR Air Fit Hyasis Sun Cream SPF50+ PA++++

Product-name correction: the Korean "에어 핏 히아시스 선크림" does NOT romanize to "Hyacis" — TIRTIR's own official site (tirtir.co.kr) and Olive Young Global (which lists this exact SKU) both spell it "Hyasis," checked 2026-09-04. A separate TIRTIR product, "Air Fit Hyasis Sun Serum," exists under a similar name but is a different item (serum, not cream) — do not conflate the two. This is a newly listed ("[NEW]") SKU on Olive Young Korea (50ml, SPF50+ PA++++), priced 25,000원 list / 20,000원 sale (20% off), with only 4 reviews so far, checked 2026-09-04 — a much smaller sample than the ₩16,000 given in the initial category-discovery snapshot, which is plausible for a brand-new listing whose price/promo is still settling. Olive Young Global carries an identically named "TIRTIR Air Fit Hyasis Sun Cream 50ml" listing (same brand, same name, same size), checked 2026-09-04 — a strong same-product signal, though the Global page is JS-rendered and its full INCI could not be fetched for a line-by-line comparison in this batch.

Is it OK for sensitive skin?

Declared facts only, not a suitability verdict: fragrance is declared; 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 8 of 58; Adenosine: rank 29 of 58; Sodium DNA (PDRN): rank 58 of 58.

Can I buy it outside Korea?

International shipping: Olive Young Global; Sold in Korea only: Olive Young Korea.

Is "Hyasis" the correct spelling, or is it "Hyacis"/"Hibiscus"?

"Hyasis" is correct — it is TIRTIR's own coined name (not a real English word), confirmed via the brand's official site tirtir.co.kr and Olive Young Global's own listing for this exact product, checked 2026-09-04. It is unrelated to "Hibiscus"; no hibiscus extract appears in Olive Young Korea's mandatory ingredient disclosure.

Is the Korean version of this sunscreen different from the export version?

No difference was confirmed at the product-name level — Olive Young Global lists an identically named, identically sized (50ml, SPF50+ PA++++) "TIRTIR Air Fit Hyasis Sun Cream," checked 2026-09-04. The Global page's ingredient list is loaded via JavaScript and could not be fetched for a line-by-line INCI comparison in this batch.

How many types of hyaluronic acid does it contain?

Olive Young Korea's mandatory disclosure lists at least seven hyaluronic-acid-family ingredients (Sodium Hyaluronate, Sodium Hyaluronate Crosspolymer, Hydrolyzed Hyaluronic Acid, Hydrolyzed Sodium Hyaluronate, Hyaluronic Acid, Potassium Hyaluronate, Hydroxypropyltrimonium Hyaluronate, Sodium Acetylated Hyaluronate), consistent with third-party marketing describing the line as using "5 types of hyaluronic acid" (an approximate, not exact, count match), checked 2026-09-04.
