Vita Niacinamide Dark Spot Serum — Triple brightening with niacinamide, tranexamic acid, and stable vitamin C — built on a sea buckthorn water base that targets dark spots without irritation.
Pine Calming Cica Ampoule — 79% Korean red pine extract meets a four-type cica complex in a lightweight ampoule built for reactive, sensitive skin.
Birch Moisturizing Sunscreen UVLock SPF 45+ — Birch sap–based daily sunscreen with SPF 45+ broad spectrum — lightweight, zero white cast, moisturizer-like finish with niacinamide and hyaluronic acid.

Niacinamide — Inhibits melanosome transfer from melanocytes to keratinocytes, which is the actual mechanism behind dark spot fading. Also strengthens the skin barrier by boosting ceramide production.
Tranexamic Acid — Blocks plasmin activity, which disrupts the inflammatory cascade that triggers melanin overproduction. Especially effective on melasma and post-inflammatory hyperpigmentation that niacinamide alone can't fully address.
3-O-Ethyl Ascorbic Acid — Converts to active ascorbic acid inside the skin. Inhibits tyrosinase — the enzyme that starts melanin production — while also scavenging free radicals that trigger pigmentation.
Sea Buckthorn Water — Sea buckthorn (Hippophae rhamnoides) contains over 190 bioactive compounds including vitamins C, E, carotenoids, and flavonoids. Using it as the base means every layer of the formula carries antioxidant activity.
Glutathione — Converts eumelanin (dark pigment) to pheomelanin (lighter pigment) by interfering with melanin synthesis pathways. Works synergistically with vitamin C — each renewing the other.
Panthenol — Converts to pantothenic acid in the skin, accelerating lipid barrier repair and reducing transepidermal water loss. Keeps skin hydrated while the actives do the brightening work.
