Dullness & dark spots

Niacinamide, vitamin C, tranexamic acid

Korean “brightening” means evening out tone, not bleaching. Niacinamide (2–10%) and vitamin C are the workhorses, and neither does anything visible without daily sunscreen — sun exposure re-darkens spots faster than any serum can fade them.

Picks for Dullness & dark spots

From 482 real user recommendations, tallied by olyoung.shop

#1
Beauty of Joseon

Relief Sun: Rice + Probiotics SPF50+ PA++++

조선미녀 릴리프 선
Key actives
Chemical filters, rice extract, grain ferment · 50ml

Why it’s here: The sunscreen that made the brand global: SPF50+ PA++++ at around ₩15,000, with filters that sit lighter than most mineral formulas.

The downside: Chemical filters can sting sensitive eyes, and it is a thin sunscreen layer rather than a moisturising one, so dry skin will want a cream under it.

₩12,000–₩18,000

The Ordinary

Niacinamide 10% + Zinc 1%

디오디너리 나이아신아마이드 10%
★ Staff pick
Key actives
Niacinamide 10%, zinc PCA 1% · 30ml

Why it’s here: Ranked in the tally with two staff picks; the cheapest way to try niacinamide at scale.

The downside: 10% is high — it stings a fair number of people. If you are new to niacinamide, 2–5% is the safer start.
