The Ordinary Niacinamide 10% + Zinc 1%
95 Korean Olive Young reviews read one by one · Official '84% recent positive' badge · #1 serum in our Threads tally (2 staff picks)
Community summary
Sebum is the center — 'less shine', 'oil control I can feel' lead at 12 mentions. It's settled into oily/dehydrated-oily users' routines (5), with pore, texture, and blemish-mark comments following (6).
The second axis is value — 'this performance at this price' repeats 10 times. The low price feeds 3-year, multi-bottle loyalty (8), and the 60ml size even gets used on back and body breakouts (5) — echoing the 'back acne slowly clearing' mention in our Threads tally.
Texture reads fast-absorbing and non-sticky (7), summer-friendly. But payoff takes 2–3 weeks, and a few reviewers reported tingling at 10% strength — start with a few drops at night.
Actual counts from the 95 reviews where sentences were clearly legible — conservative minimums, never inflated.

Downsides (mentioned repeatedly)
- Payoff takes 2–3 weeks — not an instant fixRepeated: shine reduction became noticeable after 2–3 weeks. A stay-the-course product
- 10% strength — start smallA few tingling/irritation reports — begin with a few drops at night and scale after adapting
- No official star-distribution stats capturedOnly the 84% positive badge was in this sample — numeric cross-check to be added when captured
Best for
- Oily and dehydrated-oily skin bothered by shine — the top use case
- Anyone unwilling to spend big on serums — value is this product's identity
- Extending care to back/chest breakouts (60ml size)
May not suit you if: Anyone expecting overnight change — 2–3 weeks recurs / Skin sensitive to high-strength actives — don't go full-face without patch testing
Usage tips from reviews
- Start with 2–3 drops at night, scale after adapting — the standard for high-strength actives
- Give it 2–3 weeks; repurchasers say judge only after finishing a bottle
- The 60ml covers back/chest breakouts too — repeated hack
- Light enough for morning routines — daytime sunscreen is non-negotiable
Price & buying tips
- The 60ml wins on per-ml price — go large if you know you'll repurchase
- Stock up during Olive Young sales; compare with Coupang pricing

FAQ
Q. Does the sebum control actually work?
'Less shine' leads our 95-review read (12 mentions), and the official AI summary lists 'powerful sebum control' first (84% badge). Payoff took 2–3 weeks for many, and this is a user-experience tally with individual variation — not an efficacy guarantee.
Q. Does it tingle?
A few tingling reports exist. It's a 10% active — the community standard is a few drops at night, scaling up after your skin adapts. Patch-test if sensitive.
Q. 30ml or 60ml?
First purchase: 30ml to test compatibility. Committed repurchasers go 60ml for per-ml value — 5 reviews even use it on the body.
Q. When will I see results?
2–3 weeks is the repeated timeline. It's a consistency product; judge after a full bottle, say the repurchasers.
Q. Can I use it in the morning?
7 reviews call it fast-absorbing and non-sticky enough for morning use. Daytime sunscreen is a must.
Q. What does Threads say?
#1 serum in our tally — 2 Olive Young staff picks ('the staff-pick serum') plus a 'back acne slowly clearing' body-use mention.
