Centellian 24 Review: Korea's Pharmaceutical-Backed Anti-Aging Brand, Explained
Beauty entrepreneurs found most K-beauty brands. A pharmaceutical company founded this one.
Dongkook Pharmaceutical has researched dermatology since 1968, with a particular focus on Centella Asiatica. Its skincare division built everything around a patented extraction technology called TECA, and the resulting Madeca Cream became one of Korea's best-known anti-aging products, now stocked at Ulta and Costco.
There's also something buyers need to know that the brand itself has publicly warned about.
Pros and Cons
Pros:
- Over 50 years of pharmaceutical dermatology research behind the formulas
- Patented TECA technology, not a generic Centella extract
- Won Best Peeling Gel at the 2026 NewBeauty Awards
- Free US shipping over $30, no customs or duties
- Range organised by skin concern with a routine quiz
Cons:
- Counterfeit websites charge unauthorised recurring fees
- Opened items may carry a 30% restocking fee
- Sale items and special offers are entirely non-returnable
- Buyer pays return shipping, original shipping is non-refundable
- Return authorisation required before sending anything
Start Here: The Fake Website Problem
Unusual thing to lead a review with, but it's the most financially consequential detail on this page.
Centellian 24 has publicly identified fraudulent sites impersonating the brand, selling counterfeit product made in China and charging customers through unauthorised recurring payment models. The brand specifically named madecamd.com (also trading as koriderm.com) and thecentellian24.shop.
Only centellian24usa.com and madeca.com are authorised for the US and Canada. Costco Online, Ulta and Amazon are legitimate retail channels.
Quick verification: check the domain your order confirmation came from. Anything other than @centellian24usa.com or @madeca.com should go straight to your bank as a disputed charge. Every real order generates a verifiable order number. The brand can't cancel subscriptions on sites it doesn't operate.
Since January 2026, subscriptions are only offered through the official US site.
The Madeca Cream Line
Madeca Cream Time Reverse is the flagship, now in its seventh season, running roughly $15.00 to $22.59 depending on size and promotion, with larger formats hitting $29.98 down from $39.98.
Inside: retinol, ceramide NP, a concentrated Centella TECA complex, multi-form hyaluronic acid, resveratrol and Sodium DNA. It's attempting to be an entire anti-aging routine in one jar, covering fine lines, firmness, barrier repair and oxidative protection.
Stylevana's editorial team reviewed it and highlighted twelve separate Centella extract types alongside pharmaceutical-grade Active-TECA, which is Dongkook's own purified form rather than a standard botanical extract.
Variants include Time Reverse Zero, a lighter gel-cream with Blue Active TECA for sensitive and oily skin, and the premium Expert Madeca Cream Signature.

PDRN and the Rest
Polydeoxyribonucleotide has moved from clinical settings into K-beauty over the last two years, and Centellian 24 has built a whole line around it.
The 360° Shot PDRN Active Serum sits around $30.40 on sale from $38.00, pairing PDRN with a four-type collagen complex and anti-aging peptides. A PDRN Lifting Eye Cream and Skin Tightening Glow Gel Mask round out the line.
Other lines: Mela Capture for dark spots, Matcha for exfoliation, Vital Shield, Lab Mask, and Homme for men.
Standouts elsewhere include the Madeca Vitamin 15+ Glowing Serum, the Madeca TECA Retinolsom 0.2 Firming Serum using controlled-release retinol liposome technology with bakuchiol and peptides, and the Wrinkle Capture Stick.
The Madeca Matcha Toning Peeling Gel taking Best Peeling Gel at the 2026 NewBeauty Awards is genuine external validation rather than a self-awarded badge.
What Users Say
Feedback on the Retinolsom serum is particularly useful. Reviewers with sensitive and acne-prone skin describe it as gentle enough to avoid irritation while still delivering visible retinol results, crediting the controlled-release delivery. One found it more hydrating than expected, attributing that to ten hyaluronic acid types plus NMN.
On the Madeca Cream, the recurring description is a texture that manages to feel light while still being nourishing, a balance most anti-aging creams miss by skewing heavy.
The brand's own line is that results build across four to six weeks of daily use, which is more honest than the overnight claims saturating this category.
Shipping and Returns
Stricter than average, so read this before you order.
Return authorisation is mandatory. Email sales@centellian24usa.com with your order number first. No authorisation, no refund.
Sale items and special offers are final. Given how often this brand discounts, that excludes a large share of purchases. Check whether yours was on promotion.
Opened items may face a 30% restocking fee. On a $40 cream that's $12 before you've even paid return shipping.
Approved returns cover merchandise only. Original shipping isn't refunded, you pay return postage, and the company isn't liable for lost returns, so tracked shipping is worth it.
Damaged or defective products just need an email with your order number and a photo, and they'll arrange replacement or refund.
The upside: free standard shipping across the contiguous US on orders over $30, shipped domestically so no customs or duties.

FAQs
Is Centellian 24 legitimate?
Yes. It's Dongkook Pharmaceutical's derma-cosmetic brand, operating since 1968, sold through Ulta, Costco and Amazon. Counterfeit sites exist, so buy only through official channels.
What is TECA?
Titrated Extract of Centella Asiatica, a purified pharmaceutical-grade Centella form developed by Dongkook. The entire brand is built on it.
Is Madeca Cream Time Reverse worth buying?
For the price, the formula is unusually complete, combining retinol, ceramides, multi-form hyaluronic acid and concentrated Centella. Results build over four to six weeks.
Can I return products?
Only with prior email authorisation. Sale items are excluded entirely, opened items may incur 30% restocking, and you pay return shipping.
How do I spot a fake site?
Check your order confirmation domain. Only @centellian24usa.com and @madeca.com are real.
Final Verdict
Five decades of pharmaceutical research into one ingredient is a claim almost no beauty brand can make, and it shows in formulas that feel constructed rather than assembled around a trend.
Madeca Cream Time Reverse is the obvious starting point, and at the discounted prices this brand runs regularly it's strong value for what's inside.
Two things before you order. Buy only through the official US site or a real retailer like Ulta or Costco, because the counterfeit operation is active and the brand has named the sites. And check whether your item is discounted, since sale purchases can't be returned and the standard terms already involve a restocking fee plus your own postage.
