Issue No. 16 · Sun, Oct 4
Arencia's Eraser Shot Glycolic Acid Exfoliator (200 ml) is $9.50 at StyleKorean, with DodoSkin right alongside at $9.40 - about 29% below the ~$13.30 it typically sold for across the last 60 days. Both sellers were themselves charging around $15 earlier in the series, and the pricier shops still are - YesStyle $18.90, Stylevana $19.00, Koreabe $26.26 - so two independent, trusted sellers have genuinely marked it down while the rest of the shelf hasn't. A gentle daily glycolic for under ten dollars is a real window. Verified and in stock as of Oct 4, 2026.

Issue No. 15 · Sun, Sep 27
GOODAL's Black Carrot Vita A Retinol Eye Cream (30 ml) is $13.86 at DodoSkin, about 37% below the ~$22.18 it typically sold for over the last 60 days. StyleKorean is right alongside at $14.00, so two independent sellers sit at the low, while Olive Young is still $28.00 — the old price, today. It held $22.18 for a month and a half before stepping down on September 21, and it has stayed at $13.86 for seven days. Verified and in stock as of Sep 27, 2026.

Issue No. 14 · Sun, Sep 20
Dear Klairs' Fundamental Nourishing Eye Butter (20g) is $14.50 at StyleKorean, about 45% below the ~$26.35 it typically sold for over the last 60 days. This is the rare one we can show you rather than ask you to take on faith: DodoSkin is at $15.21, so two independent sellers sit near the low, while Stylevana is still $20.40 and BuyBeautyKorea is still $26.00 — the old price, today. It stepped down on September 3 and has held $14.50 for seven days. A rich eye cream at under $15 is a genuinely good window. Verified and in stock as of Sep 20, 2026.

Issue No. 13 · Sun, Sep 13
mixsoon's PDRN Collagen Cream is $11 at StyleKorean, about 53% below the ~$23.39 it has typically sold for over the last 60 days. Four sellers we track carry it right now — StyleKorean at $11, Koreabe at $13.57, Stylevana at $16.25 and Amazon at $21.50 — so this is one we can check against other shelves rather than against a crossed-out list price. The low has held five days across sixty-one price checks. If you want a light plumping moisturizer, this is a good window; skip it if your routine already has a rich cream you love. Verified and in stock as of Sep 13, 2026.

Issue No. 12 · Sun, Sep 6
medicube's Azelaic Acid 16 BB Calming Serum has been sitting at $19.89 at Stylevana — about 54% below the ~$42.89 it typically sells for over the last 60 days. I waited before calling it: the low has held 16 days across 61 checks, so this is a real shelf price, not a one-day flicker. If a 16% azelaic + niacinamide serum for redness and bumpy texture has been on your list, this is a genuinely good moment. Verified and in stock as of Sep 6, 2026.
Issue No. 11 · Sun, Aug 30
Last week we flagged Mediheal's Madecassoside cica pad as about 38% off — down to $24 from $38.99. That was our error, and we'd rather be straight about it. The $38.99 was Olive Young's 100+100 (200-count) double set; the $24 is a single 100-count tub at Soko Glam. Per pad, they're the same price — so there was no real drop. We've pulled the deal and tightened our checks so a pack-size mismatch can't be mistaken for a sale again. The honest read: a single tub runs about $24 at Soko Glam, verified and in stock, as of Aug 30, 2026.

Issue No. 10 · Sun, Aug 23
The featherweight hyaluronic serum that a lot of you layer under everything is down to $11.39 at Stylevana — verified and in stock — from the $14.00 it had been sitting at, about a 19% drop and the lowest I've tracked it. Six clean sources agree it's the real thing at a real price. Was $14.00; as of Aug 23, 2026.

Issue No. 9 · Sun, Aug 16
The cult, no-white-cast SPF50+ stick that reapplies over makeup is down to $14.00 at Stylevana — verified and in stock — from the $21.99 it had been holding, about a 36% drop. It's the lowest I've tracked it, and with August sun still doing its thing, this is the one I'd grab now. Was $21.99; as of Aug 16, 2026.

Issue No. 7 · Sun, Aug 9
The lightweight, no-white-cast SPF50+ people rebuy on repeat is down to $13.72 at Stylevana, from the $21.90 I logged a week ago — a verified, in-stock listing, not a mystery third-party seller. Was $21.90; as of Aug 9, 2026.

Issue No. 5 · Sun, Aug 2
innisfree's Volcanic PHA Pore Refining Toner (170 ml) dropped to $10.49 at Stylevana this week — down about 34% from $16.00 a week ago, and the lowest I've tracked it. It's a verified, authentic listing, and the next authentic seller still sits at $16.00, so this is a real markdown, not a phantom price. A gentle, gel-textured PHA toner to smooth and de-gunk pores without the sting of a stronger acid.

Issue No. 3 · Sun, Jul 26
The lightweight, fragrance-free hydrating essence dropped from $17.99 to $10.79 this week at Stylevana — verified authentic, and the lowest I've tracked it. Three other authentic sellers still run well above that, up to about $31, so this is a real markdown, not a phantom price. If a no-frills hydration layer is missing from your summer routine, this is the week.

Issue No. 4 · Sun, Jul 26
This lightweight, no-white-cast daily SPF50+ dropped to $14.00 at Stylevana this week — down about 39% from $23.12, and the lowest I've tracked it. It's a verified, authentic listing, and the next authentic seller still sits at $24.50, so this is a real markdown, not a phantom price. If you've been meaning to retire a heavy, pilling sunscreen before the worst of the summer heat, this is the week to do it.

Issue No. 2 · Sun, Jul 19
The viral clay-and-mud pore mask dropped from $25.19 to $15.12 this week — verified authentic at Amazon, and about as low as I've tracked it. Four other authentic sellers still sit near $20, so this is a real markdown, not a phantom price. If a mud mask is on your list for summer's sweatier pores, this is the week.

Issue No. 1 · Sat, Jul 18
The cult collagen moisturizer fell from $26.46 to $15.88 this week — verified authentic at Stylevana, and about as low as we've seen it. If you've been meaning to try it, now's the week.
