5 Best Korean Picks for Hyperpigmentation, by Olive Young Sales
Five serums and creams whose Korean names talk about marks, spots or pigment, ordered by rule from Olive Young Korea's skincare rankings of 6 Sep, 1 Oct and 13 Oct 2026, with Hwahae scores of 14 Oct 2026.
5 products compared · Korean data as of Olive Young Korea 13 Oct 2026 · Hwahae 14 Oct 2026
If you order from the US, start with numbuzin's No.5+ Glutathione Vitamin Concentrated Serum: #46 in Olive Young Korea's skincare ranking on 13 Oct 2026, and its Amazon US listing matches the Korean ingredient list. MEDIHEAL's serum leads Korea's data but has no US link here.
These are what Koreans buy, not proof that anything evens out your tone; we did not test them on skin.

MEDIHEAL Madecassoside Derma Serum
best for: The one Korea buys most now
Korea's numbers:Skincare rank: #1 (13 Oct) · #30 (1 Oct) · #9 (6 Sep)(Olive Young Korea, 13 Oct 2026)
MEDIHEAL
Derma Serum Madecassoside Moisture Blemish
50 ml
MEDIHEAL's madecassoside serum climbed to #1 in Olive Young Korea's skincare ranking on 13 Oct 2026, after #9 on 6 Sep and #30 on 1 Oct, each time as a 50 ml + 50 ml set. Only its 6 Sep listing name mentioned marks; Olive Young Korea's later listing carries an identical ingredient notice. That list puts niacinamide fifth and madecassoside at 1,080 ppm, and the serum passed Korea's functional-cosmetic filing.

Watch out: The US listings we opened on 14 Oct 2026 were other MEDIHEAL madecassoside products, so this page links no US store for it. Hwahae shows no entry under this serum's name, so there is no Hwahae score here.
Texture: A watery serum in a square dropper bottle.

Anua's Niacinamide 10 TXA 4 Serum held #13 in Olive Young Korea's skincare ranking on 1 Oct and 13 Oct 2026, after #61 on 6 Sep, always as a 30 ml two-pack.

Dongkook
MELA-SET Toning Cream
35 g
Dongkook's MELA-SET Toning Cream comes from Dongkook Pharmaceutical but is sold in Korea as a cosmetic: Olive Young's ingredient notice for it is a cosmetic notice, and it passed Korea's functional-cosmetic filing. It was #20 in Olive Young Korea's skincare ranking on 1 Oct 2026 and #61 on 13 Oct, as a 35 g double set with stick-on patches. Arbutin, alpha-arbutin, niacinamide and tranexamic acid are on its Korean list.

You want Hwahae ratings to back the pick
Watch out: Hwahae shows a single review for it on 14 Oct 2026, too few to read anything into. It is a newer entry: absent from the 6 Sep ranking, and this page links no US store for it.
Texture: A white cream in a squeeze tube.

How we picked
Pool: every product in Olive Young Korea's skincare sales ranking Top 100 on 6 Sep, 1 Oct and 13 Oct 2026 whose Korean listing name, leaving out promo brackets and gift lists, names spots, marks, pigment or tranexamic acid.
Left out: a device, products already picked on our other Best 5 lists, and a retinol ampoule whose name puts retinol first (it is on our aging list).
Order: how many of the three Olive Young Korea skincare rankings each product appears in, then its median rank (missing = 101), then its 13 Oct rank. Price and commission play no part.
3 of the 5 products with an Olive Young Korea rank reached it through a promotional listing (influencer pick, Olive Young pick, collab or sale).
Ranked products that came from a gift-set or bonus listing (an extra item or a second unit in the pack): 5 of 5 — a rank can partly reflect the deal.
None of these was tested on skin by us; the order comes from the Korean data on this page.
For most US readers, numbuzin's No.5+ Glutathione Vitamin Concentrated Serum is the pick.
It ranked #46 in Olive Young Korea's skincare ranking on 13 Oct 2026, and the Amazon US listing we link showed the Korean ingredient list in the same order on 14 Oct 2026. In Seoul, MEDIHEAL's serum is the one Koreans are buying most: #1 in Olive Young Korea's skincare ranking on 13 Oct 2026.
Which tone-care product do Koreans buy the most right now?
MEDIHEAL's madecassoside serum was #1 in Olive Young Korea's skincare ranking on 13 Oct 2026, as a Seoul-edition double set. Over the three dates we use, it also has the lowest median rank of the five. Olive Young does not publish how it ranks, so we combine 6 Sep, 1 Oct and 13 Oct.
Is the numbuzin serum on Amazon US the same as in Korea?
Yes for the listing we link: numbuzin's Amazon US 'No.5 Vitamin Concentrated Serum' matched Olive Young Korea's ingredient order on 14 Oct 2026. It is sold by PSB Retail. The 'No.5+' list on Olive Young US was ordered differently, so we did not count that one as the Korean version.
Can these products help with hyperpigmentation?
Seoulvanie cannot promise that, because we did not test these five on skin. Our list only shows what Koreans buy and what the Korean labels list. Persistent or spreading hyperpigmentation can have medical causes, so see a doctor about it rather than relying on a serum.
Can I use Anua's serum around children or while pregnant?
No for young children: Anua's Korean label says not to use the Niacinamide 10 TXA 4 Serum on children aged 3 and under. It also notes that papules and mild itching were reported with arbutin. For pregnancy, ask your doctor before starting any of these five.
Why is a pharmaceutical company's cream on this list?
Dongkook's MELA-SET Toning Cream is made for Dongkook Pharmaceutical but sold in Korea as a cosmetic. Olive Young Korea's notice for it follows the cosmetic format and states that it passed the functional-cosmetic filing, so it qualified like the other four.
More questionsWhich of these five suits sensitive or fragrance-averse skin?
Anua's and numbuzin's serums list no essential oils, while goodal's names bergamot, lavender, lemon and orange oils plus limonene and linalool. Olive Young Korea's notices list all five for all skin types, with no sensitive-skin label. Patch-test first, and skip goodal's serum if fragrance bothers you.
Why is Innisfree's retinol ampoule not here?
Innisfree's Retinol Cica ampoule matched both this list and our aging list, and its Korean name puts retinol first. Our rule therefore placed it on our list for aging skin, and each product appears on one of these concern lists only, so the two lists never repeat a pick.
