A 55 ml serum from the Red line, built on tea tree oil at what the brand calls a high concentration without publishing a figure, so we are not going to invent one. The Plus size is unusually large for a targeted serum, which reflects how it is used in Korea: over the whole face daily during a bad stretch rather than dotted on single spots.
Who it's for. Blemish-prone and easily upset skin with congestion; the brand states the formula is certified non-comedogenic.
How to use. After toner, press two to three drops over face and neck, or over the areas that break out most. Follow with moisturiser, morning and evening.
Key active. Tea tree oil, the long-standing Korean choice for blemish-prone skin, used here for its soothing and sebum-balancing role alongside the serum's moisturising base.
Sourced in Seoul. This is the Korean domestic SKU, not a reformulated export version.
All orders ship from South Korea. Your order is picked and packed by our logistics partner in Bucheon-si, Gyeonggi-do, then travels to the United States as an international shipment.
Handling 1-3 business days, international transit and customs clearance 7-11 business days. Total estimated delivery 8-14 business days. These are estimates, not guarantees.
Free shipping on orders $120+; a flat $12.99 below that. The $120 threshold applies to your order total after any automatic discount. Product prices do not include U.S. import duties or customs fees, which are billed by the carrier and are the responsibility of the recipient.
You may request a return within 30 days of delivery on unused, unopened items. Returns ship to our facility in South Korea and require a Return Authorization Number, which you must request from us before sending anything.
The full ingredient list (INCI) is printed on the product packaging. These are authentic Korean-market formulations sourced directly in Seoul - the domestic SKU, not a reformulated export version.
