Centellian24 launched Madeca Star-Tok Serum All Tight on September 23, 2026, with TECA-TOCK™ raised to 500,000 ppm and two new firming actives added.
Madeca Star-Tok All Tight Serum vs Original: What Actually Changed
| Launch date | September 23, 2026 |
|---|---|
| TECA-TOCK™ concentration | 500,000 ppm |
| Key actives | TECA + PLA + botulinum-like peptide |
| Position | Upgrade of the existing Star-Tok serum line |
| Launch price and ml | Not yet listed on official pages |
| Where to check | Olive Young Global, Dongkook official mall |
The confirmed change is the number: All Tight carries TECA-TOCK™ at 500,000 ppm, and it adds PLA and a botulinum-like peptide to the same platform the original serum used.
TECA-TOCK™ combines TECA, a centella extract, with PLA and the peptide, so the upgrade is a stronger mix of the same actives rather than a new ingredient family.
The original Star-Tok serum’s exact concentration is not stated on any primary page, so a precise ppm-to-ppm comparison is not possible yet.
Prior Korean press coverage suggested a lower figure, but treat any exact number you see online as unverified.
If you are comparing the two serums, the safe baseline is the 500,000 ppm figure on All Tight alone; wait for official specs on the original before judging how much stronger the new one is.
What TECA, PLA and the Botulinum-Like Peptide Do
| Ingredient | What it is | What it does in this serum |
|---|---|---|
| TECA | A standardized four-compound extract of centella asiatica — madecassoside, asiaticoside, madecassic acid and asiatic acid | The core active of the whole Madeca line; used for soothing and barrier repair, and the Star-Tok line simply raises how much of it goes in |
| PLA (poly-lactic acid) | The firmness-supporting active | Same ingredient family Korean lifting serums use |
| Botulinum-like peptide | A cosmetic active, not an injectable | Works on the look of expression lines; it cannot relax muscle the way a shot does |
If your goal is soothing and barrier care, the TECA side is the real change here.
If you buy expecting needle-like wrinkle results from the peptide, you will be disappointed.
How to Buy Madeca Star-Tok All Tight From Abroad
Two channels cover Centellian24 for overseas buyers: Olive Young Global and Dongkook’s official online mall.
- Check Olive Young Global first — it is the English-language site, ships to multiple countries, and typical delivery runs about 3-7 business days with a free-shipping threshold that varies by country.
- Check Dongkook’s official mall second, because it often runs launch-period promos that third-party sites do not list.
- Confirm the exact All Tight SKU is listed before you check out — stock of this specific product on Global and the official mall’s overseas shipping policy are not confirmed yet.
If you need it fast, check Global stock daily for the first weeks; if you are flexible, watching the official mall’s launch promo can save you money.
How Much Does It Cost in Korea?
No launch price or ml capacity for All Tight is confirmed on any official page as of September 26, 2026.
The only honest reference is history: Centellian24 flagship serums have consistently launched in the 30,000-45,000 KRW band on Olive Young.
That band tells you the likely bracket, not this product’s price, and a number quoted on a blog or news recap without an official source is not a price.
If a seller lists All Tight today at a firm price, check whether the product page itself shows it; if not, wait for Dongkook or Olive Young to publish the official figure.
Should You Switch If You Already Use the Original?
The switch decision rests on three numbers that are only partly on the table: All Tight’s 500,000 ppm is confirmed, but its price, its ml, and the original serum’s concentration are not.
On paper the ppm jump is real, yet without the original’s verified figure you cannot size the actual difference.
It is also not confirmed whether All Tight replaces the original or sells alongside it, which matters if you want to keep buying your current bottle.
If you are mid-bottle on the original, the sensible move is to wait for official specs before reordering — and if you finish it sooner, the original remains the product with a known price and size.
Why Every Korean Outlet Ran the Same Story This Week
The All Tight release is one item in a fall 2026 cluster of pharmaceutical derma-cosmetics launches, and the same press material spread across multiple Korean outlets around September 23, 2026.
Other centella-based brands also pushed firming serums in the same window, so this sits inside a seasonal tightening cycle rather than standing alone.
What that means for you: most coverage right now is one press package, not independent reviews, so judge the product by its listed specs instead of the volume of articles.
If you are comparing All Tight against other fall firming serums, wait for independent listings and real retail pages, not launch-day recaps.
If I were already using the original, I’d wait for the official price before switching, because none of the specs that would justify the jump have been confirmed yet.
What I check first is the official product page, not the launch articles, since the price and capacity are still unverified.

FAQ
Q. Madeca Star-Tok Serum All Tight vs original — what’s the difference?
All Tight carries TECA-TOCK™ at 500,000 ppm and adds PLA plus a botulinum-like peptide; the original’s concentration is not verified, so the confirmed difference is the higher stated ppm and the two added actives.
Q. Where to buy Madeca Star-Tok Serum All Tight overseas?
Check Olive Young Global first (English site, about 3-7 business days shipping) and Dongkook’s official mall second; stock of this exact SKU abroad is not confirmed as of September 26, 2026.
Q. How much does Madeca Star-Tok All Tight cost?
No official price or ml capacity is published yet; Centellian24 flagship serums have historically launched at 30,000-45,000 KRW, with the prior Star-Tok at about ₩39,000 for 30ml.
Q. Does the botulinum-like peptide work like botox?
No — in a serum it is a cosmetic active for the look of fine lines and does not relax muscle the way injectables do.
Q. Should I switch from the original Star-Tok serum?
If you are mid-bottle, waiting for the official price, ml and a verified original-concentration figure is the safe call; the 500,000 ppm figure alone does not yet tell you the full gap.
