Green Tangerine Vita C Dark Spot Serum

Name: Goodal Green Tangerine Vita C Dark Spot Serum
Brand: Goodal

Korea ranking #8 serumUS stock

A brightening serum built on 70 percent green tangerine extract — unripe citrus harvested early on Jeju Island — aimed at dark spots, post-blemish marks, and general dullness. The texture is light and watery, and the vitamin C comes in gentle derivative form, which makes this an easy first brightening serum rather than a strong one.

More detail

The brightening work is shared by ascorbyl glucoside (a stable vitamin C derivative), arbutin, and niacinamide, which interfere with the process that forms dark spots, while centella and licorice extracts keep things calm. The 70 percent green tangerine extract base gives it a light, watery-gel texture that layers easily under moisturizer. Use it morning and night after toner; in the morning, follow with sunscreen — without it, the spots you're fading keep getting reinforced. Results with derivative-based vitamin C build gradually over weeks rather than days. The formula includes several fragrant citrus and flower oils (bergamot, lemon peel, lavender, ylang-ylang), so very sensitive or fragrance-avoidant skin should patch test first.

Grade B — Derivative vitamin C: gentler but less potent than L-AA; honest for beginners, not for stubborn melasma.
