The renewed Alpha formula of Goodal's bestselling Korean vitamin C serum — now upgraded with a 4-form Vitamin C complex, Glutathione, CoQ10 (Ubiquinone), and Thioctic Acid for a more complete brightening and antioxidant system. 

Lightweight, fast-absorbing. Free from 20 harmful ingredients. 40ml.

• Four Forms of Vitamin C — The Alpha Upgrade — Each fi reaches pigment at a different stage, which is why this gets to marks a single-form serum leaves behind.
• Green Tangerine Extract — The Base — listed before water. Unripe green tangerines are one of the richest natural vitamin C sources, so the whole formula is brightening, not just the actives in it.
• 5% Niacinamide — Evens Tone, Refines Pores — stops pigment from transferring into skin cells, fades existing spots, and strengthens the barrier at the same time.
• Glutathione — A Separate Brightening Route — interrupts pigment production at a different point than vitamin C, so the two work in parallel rather than overlapping.
• CoQ10 — Antioxidant Protection — defends against the oxidative stress that drives discoloration and dullness in the first place.
• Thioctic Acid — Keeps the Other Antioxidants Working — alpha lipoic acid recycles the vitamin C and CoQ10 in the formula, so they stay active longer on the skin.
• Cica Complex — Calms Post-Acne Marks — madecassoside, asiaticoside, and centella extracts settle redness and support recovery. This is what makes a strong vitamin C serum workable on PIE and sensitive skin.
• Licorice Root — Targets Stubborn Discoloration — a well-established brightening botanical, layered in alongside the vitamin C.
• Adenosine — Firms and Smooths — works on fine lines and elasticity, so the serum earns a place in an anti-aging routine too.
• Absorbs Fast, No Sticky Film — reviewers consistently say it sinks in quickly and layers cleanly under sunscreen and makeup.
