Goodal Green Tangerine vs Some By Mi Yuja Niacin (Brightening Serums)
Two of K-beauty’s most popular affordable brightening serums, head to head: Goodal Green Tangerine Vita C vs Some By Mi Yuja Niacin. Both use citrus-derived vitamin C plus niacinamide to even tone and fade marks — but they lean in different directions, one gentler and hydrating, the other a busier blemish-and-brightening multitasker.
Last verified: June 2026. Formulas change — we re-check periodically.
The short answer (TL;DR)
- Goodal Green Tangerine — gentler, vitamin-C-forward (green tangerine) with 4% niacinamide, centella and HA. Best for dullness, even tone and sensitive-leaning skin.
- Some By Mi Yuja Niacin — 5% niacinamide plus 82% yuja (a vitamin-C derivative), glutathione and arbutin. Best for blemish-prone skin and post-acne marks wanting more actives.
- Gentle brightening → Goodal. Blemish + marks, more actives → Some By Mi (mind the citrus/scent).

What each one is
Goodal Green Tangerine Vita C is a best-selling, gentle vitamin C built on green tangerine extract with 4% niacinamide, centella and hyaluronic acid — brightening without the sting of pure ascorbic acid, and soothing/hydrating enough for sensitive-leaning skin.
Some By Mi Yuja Niacin packs 82% yuja (citron) — a vitamin-C-rich citrus delivered as sodium ascorbyl phosphate — with 5% niacinamide, glutathione, arbutin and licorice. It’s a busier, more blemish-and-marks-focused multitasker in a watery-gel with a citrus scent.
How they differ for your skin
Both brighten via citrus vitamin C + niacinamide, so there’s real overlap. The split is gentleness vs active load: Goodal is the calmer, more hydrating pick (centella, lighter), better for sensitive skin and everyday dullness. Some By Mi brings more brightening actives (glutathione, arbutin) and slightly more niacinamide, aimed at clearing post-acne marks — but its high citrus content and scent can bother very reactive skin.
Which should you buy?
- Sensitive or dullness-focused → Goodal Green Tangerine.
- Blemish-prone, fading acne marks → Some By Mi Yuja Niacin.
- Fragrance/citrus-sensitive → Goodal (Some By Mi has a citrus scent).
- Want more actives in one bottle → Some By Mi.
What they won’t do / who should skip
- Neither is a strong “pure vitamin C” — they’re gentle, derivative/extract-based brighteners (a plus for tolerance, a limit for maximum potency).
- Very reactive skin should patch-test Some By Mi (citrus + scent).
- Neither treats active acne — they help marks and tone, not breakouts themselves.
- Both need daily SPF to actually fade pigmentation.
The verdict & where to buy
Pick Goodal for gentle, hydrating brightening and sensitive skin; pick Some By Mi if you’re blemish-prone and want more brightening actives to tackle post-acne marks. Prices vary by retailer and region — the buttons route you to the best option for your country.

FAQ
Goodal Green Tangerine or Some By Mi Yuja Niacin — which is better? Goodal is the gentler, more hydrating vitamin-C-forward brightener (great for sensitive skin and dullness); Some By Mi packs more actives — 5% niacinamide plus glutathione and arbutin — aimed at blemish-prone skin and post-acne marks, but with more citrus and a scent.
Do both contain vitamin C? Yes, both use citrus-derived vitamin C (Goodal: green tangerine; Some By Mi: 82% yuja with a sodium ascorbyl phosphate derivative) plus niacinamide — so they overlap, but Some By Mi leans more “blemish + brightening” with extra actives.
Which is better for sensitive skin? Goodal — it’s gentler, with soothing centella and a lighter active load. Some By Mi’s high citrus content and fragrance can bother very reactive skin, so patch-test.
Which is better for dark spots and acne marks? Some By Mi has the edge for post-acne marks thanks to niacinamide + glutathione + arbutin; Goodal is better for general dullness and even tone. Either way, daily SPF does the heavy lifting.
Can I use them with other actives? Yes — both pair fine with niacinamide (they contain it) and most hydrators; introduce alongside retinoids or strong acids slowly. Use in the morning with SPF, or PM.
