Both are specifically positioned for dark spots and pigmentation, but they reach for entirely different active-ingredient strategies to get there.

Why compare these two specifically

Both explicitly target dark spots, which makes this a genuine head-to-head for the same shopper intent, natural vitamin C extract versus a clinical-concentration niacinamide and tranexamic acid pairing, plus a real fragrance difference worth knowing.

Price per milliliter

Goodal runs $0.58 per milliliter ($23.00 for 40mL). Anua runs $0.73 per milliliter (Amazon, checked 17 October 2026). Goodal is somewhat cheaper per mL.

Natural vitamin C vs. clinical niacinamide-TXA pairing

Goodal centers on green tangerine extract at a genuine 70% concentration, a naturally-derived vitamin C source, alongside niacinamide and glutathione. Anua pairs niacinamide at a meaningful 10% concentration with 4% tranexamic acid, a more clinically-concentrated approach specifically aimed at stubborn hyperpigmentation.

A real fragrance difference

Goodal contains fragrance via multiple essential oils, confirmed across independent current retailer listings. Anua is confirmed fragrance-free. For fragrance-sensitive skin dealing with dark spots, that's a real, practical factor beyond just active-ingredient strategy.

Our take

If you want a more clinically-concentrated, targeted formula and prefer fragrance-free, Anua's niacinamide-and-TXA pairing is the more purposeful pick for stubborn pigmentation specifically. If a naturally-derived vitamin C source with a genuine bestseller record and a lower price matters more, and fragrance isn't a dealbreaker, Goodal is the better-value option.

Goodal Green Tangerine Vita C Dark Spot Care Serum Alpha: $0.58/mL. A natural, 70%-concentration green tangerine vitamin C source with a genuine bestseller record, though it contains fragrance.

Anua Niacinamide 10% + TXA 4% Serum: $0.73/mL (Amazon, checked 17 October 2026). A clinically-concentrated, fragrance-free niacinamide-and-tranexamic-acid pairing specifically targeted at stubborn hyperpigmentation.
