COSRX 6 Peptide Skin Booster vs Centellian24 Madeca Cream Time Reverse
Two peptide products, two formats. One is a large, cheap booster you can use like a toner; the other is a treatment cream with centella alongside.
| COSRX | Centellian24 | |
|---|---|---|
| Key actives | Six peptides | Madecassoside, peptides |
| Format | Booster serum, 150 ml | Cream, 50 ml |
| Texture | Watery, closer to an essence than a serum | Proper cream, richer finish |
| Stated goals | Firmness, fine lines | Firmness, fine lines |
| Size & price | 150 ml, about $25 | 50 ml, about $32 |
| Cost per ml | About $0.17 | About $0.64 |
| Best for | First-time peptide users, oily skin, big-volume habits | Dry or sensitive skin wanting soothing and firming in one step |
| Who should skip it | Dry skin expecting it to moisturise on its own | Oily skin in warm weather |
The verdict
COSRX is the low-risk entry point: 150 ml at about $25 means you can use peptides generously for months without thinking about cost, but it is a light layer that still needs a moisturiser over it. Centellian24 is a finishing cream that combines peptides with centella-derived madecassoside, which suits drier or reactive skin better. Choose by format and skin type — the peptide content is not the deciding factor.

The short version
Peptides are the gentlest of the anti-ageing ingredient families, and these are two very different ways to get them. COSRX’s The 6 Peptide Skin Booster Serum is a 150 ml bottle you use like a watery first layer. Centellian24’s Madeca Cream Time Reverse is a 50 ml treatment cream from a Korean pharmacy brand, reformulated every season, with centella at its centre alongside peptides.
What each one is built on
Six peptides in a big bottle
Peptides are short chains of amino acids used in cosmetics to support firmness and the look of fine lines. They are slow, unglamorous and very well tolerated — no purging, no sun sensitivity, no schedule to negotiate. COSRX’s format choice is the interesting part: at 150 ml for about $25, this is priced to be used with a heavy hand, which is unusual in a category where 30 ml bottles are the norm.
Madecassoside plus peptides
Madecassoside is one of the active fractions isolated from centella asiatica, and it is the ingredient Centellian24 built its reputation on in Korean pharmacies. Pairing it with peptides gives you soothing and firming claims in one step. The “Season 7” naming reflects an annual reformulation, so the version on the shelf will not be identical to the one someone reviewed three years ago.
Format decides how you use them
The COSRX booster is thin and fast, closer to an essence. It goes on early, layers under everything, and does not moisturise on its own — dry skin will still need a cream on top. That makes it an addition to a routine rather than a replacement for part of one.
The Madeca cream is the last step. It is richer, it finishes the routine, and on oily skin in summer it will feel like too much. On dry or reactive skin in winter it is doing two jobs at once, which is the argument for its higher price.
Price, honestly
About $0.17 per millilitre against about $0.64 is close to a fourfold difference, and it deserves stating plainly rather than dressing up. You are not paying that premium for more peptides; you are paying for a cream base, a soothing active and a pharmacy brand. Whether that is worth it depends on whether you actually need the cream.
Which one fits your skin
- Choose the COSRX booster if peptides are new to you, your skin is oily or combination, or you want an easy, cheap way to add a firming step without disturbing what already works.
- Choose the Madeca cream if your skin is dry or easily reddened and you would rather upgrade your moisturiser than add a bottle.
- Layering both is harmless and mildly redundant: booster first, cream last, if you happen to own both.
Expectations worth setting
Peptides are a maintenance ingredient, not a correction. If your goal is visible change in deeper lines, a retinoid is the ingredient with the strongest evidence behind it, and peptides sit alongside it comfortably as the gentle half of the routine. Give either of these three months, and judge on skin comfort and overall look rather than on any single line in the mirror.
Frequently asked
Do peptides really work for fine lines?
Peptides are a maintenance ingredient with modest evidence: slow, unglamorous and very well tolerated, with no purging or sun sensitivity. If your goal is visible change in deeper lines, a retinoid has the stronger evidence behind it u2014 our retinal vs retinol guide covers where to start.
Can I use a peptide booster and a peptide cream together?
You can u2014 booster first, cream last u2014 but it is mildly redundant. You are paying twice for the same ingredient family rather than adding a second mechanism to the routine.
Does the COSRX 6 Peptide Booster replace a moisturizer?
No. It is a thin, watery first layer closer to an essence than a serum, and dry skin will still need a cream over the top of it.
What is madecassoside and how is it different from centella?
Madecassoside is one of the active fractions isolated from centella asiatica, so it is a more defined version of the same soothing story. It is the ingredient Centellian24 built its reputation on in Korean pharmacies.
Why does Centellian24 keep changing the Madeca Cream formula?
The season naming reflects an annual reformulation, so the jar currently on sale is not identical to the one someone reviewed three years ago. Worth remembering if you are buying on the strength of an older review.
