Rejuran Ampoules Compared: What’s the Difference and Which One Should You Choose?
Most Rejuran ampoules contain the same 0.5% concentration of c-PDRN, so the biggest differences come from the rest of the formula rather than the PDRN itself. Some are built more around hydration and barrier support, while others add ingredients for brightening, exfoliation, or overall skin texture.
In this guide, I’ll compare the Rejuran ampoules side by side, look at what actually changes between the formulas, and explain which one makes the most sense depending on your skin type and main concerns.
At a Glance: How the Rejuran Ampoules Differ
In this guide, I'll break down what separates the Rejuran ampoules and how their formulas differ, combining firsthand observations with ingredient analysis informed by my medical and cosmetology background.

Looking Beyond the c-PDRN
Almost all of the Rejuran ampoules in this comparison contain 0.5% c-PDRN, so the PDRN concentration is not what really separates them. The bigger differences come from the supporting ingredients and the skin concerns each formula is built around.
The official Rejuran ampoule range includes formulas for different concerns, while individual product pages show how much the supporting ingredients can change from one ampoule to another. For example, the Turnover Ampoule combines c-PDRN with niacinamide, arbutin, bisabolol, and hyaluronic acid.
The newer formulas take very different directions. Some focus more on hydration and barrier support, while others add exfoliating acids, brightening ingredients, or ferment-based components.
So rather than thinking of them as six versions of the same PDRN serum, it makes more sense to see them as different formulas that share the same c-PDRN foundation.
If you want to go deeper into PDRN itself, including how it works, what the evidence actually supports, and how Rejuran compares with other Korean and Western PDRN products, you can explore my dedicated PDRN guides below.
Rejuran Turnover Ampoule
The Turnover Ampoule is the original Rejuran serum and the simplest formula in the lineup. If you're trying to understand how the other ampoules differ, this is the best place to start.
Alongside 0.5% c-PDRN, the formula contains niacinamide, arbutin, bisabolol, and sodium hyaluronate. Compared with the newer additions to the range, the ingredient list feels relatively straightforward, focusing on hydration, brightening, and overall skin maintenance rather than any highly specialized concern.
Unlike the newer ampoules, it does not emphasize pores, exfoliation, intensive barrier repair, or microbiome support. In many ways, it represents the classic Rejuran concept before the lineup expanded into more targeted formulas.
Best For
✓ Normal skin
✓ Combination skin
✓ First-time Rejuran users
✓ General skin maintenance
I generally recommend the Turnover Ampoule to anyone who wants to start with the classic Rejuran formula before exploring the more specialized options in the lineup. If your primary goal is to experience c-PDRN itself rather than focus on a specific concern, this is the version I would recommend starting with.
Where to buy
Rejuran Dual Effect Ampoule
The Dual Effect Ampoule builds on the original Turnover Ampoule formula but places a stronger emphasis on hydration and barrier support.
While the original formula focuses primarily on c-PDRN, hydration, and brightening, the Dual Effect Ampoule introduces ceramides, cholesterol, and squalane, ingredients commonly associated with barrier-focused skincare. As a result, it feels like a more rounded version of the original rather than a completely different product.
Texture
Compared with the original Turnover Ampoule, the Dual Effect Ampoule had a slightly opaque appearance and a medium-weight texture. It felt richer than the Pore Tightening Ampoule but lighter than the Moisture Treatment Ampoule.
The inclusion of ceramides, cholesterol, and squalane likely contributes to its more cushioned feel while maintaining good spreadability.
Best For
✓ Normal skin
✓ Dry skin
✓ Dehydrated skin
✓ Mild barrier weakness
If your skin feels tight, dehydrated, or struggles to retain moisture, I would generally choose the Dual Effect Ampoule over the original Turnover formula. It retains the familiar Rejuran approach while providing additional barrier support.
Rejuran Moisture Treatment Ampoule
The Moisture Treatment Ampoule takes the barrier-supportive approach of the Dual Effect Ampoule even further. Looking at both the texture and the ingredient list, this is clearly one of the most hydration-focused formulas in the Rejuran lineup.
Ceramides, cholesterol, squalane, hydrogenated lecithin, and additional lipid-supporting ingredients give the formula a profile that feels closer to a barrier-support moisturizer than a lightweight hydrating serum.
Texture
Among the tester products I examined, the Moisture Treatment Ampoule appeared to have the richest texture and highest viscosity. The droplet held its shape well and remained suspended from the pipette longer than the other formulas.
This observation aligns closely with the ingredient list. The formula contains multiple barrier-supportive lipids that help explain its richer consistency.
Best For
✓ Dry skin
✓ Very dry skin
✓ Dehydrated skin
✓ Compromised skin barrier
If hydration is your primary concern, this is the Rejuran ampoule I would be most likely to choose. Among the current formulas, it places the strongest emphasis on moisture retention and barrier support.
Where to buy
Rejuran Pore Tightening Ampoule
The Pore Tightening Ampoule is arguably the most unusual formula in the Rejuran lineup. While most Rejuran ampoules focus on hydration, barrier support, or skin renewal, this formula is built around exfoliation and pore care.
What immediately stood out to me is the acid blend. PHA, AHA, BHA, and LHA all appear in the formula alongside niacinamide, making it fundamentally different from the rest of the lineup.
Texture
In contrast, the Pore Tightening Ampoule was the lightest formula. It spread quickly and lacked the richer, cushioned feel of the Dual Effect and Moisture Treatment Ampoules.
Best For
✓ Combination skin
✓ Uneven texture
✓ Excess oil
If your main goal is smoother skin texture and improved pore appearance, this is the most specialized formula in the lineup.
Where to buy
Rejuran Triple Radiance Ampoule
The Triple Radiance Ampoule takes a different approach from the barrier-focused formulas in the lineup. Rather than emphasizing hydration or barrier repair, it is designed to support brighter, more radiant-looking skin.
Niacinamide appears high in the ingredient list and is supported by licorice extract, while panthenol and humectants help maintain hydration. Looking at the formula as a whole, this is clearly the most glow-focused product in the Rejuran range.
Texture
Somewhere between a serum and a lightweight gel, the Triple Radiance Ampoule had a cushiony gel-serum texture that sat on the skin slightly longer before spreading. It felt more substantial than the Pore Tightening Ampoule but lighter than the Moisture Treatment Ampoule.
Best For
✓ Normal skin
✓ Combination skin
✓ Dry skin
✓ Dull skin
✓ Uneven skin tone
If your skin looks tired, dull, or lacks radiance, this is the Rejuran ampoule I would be most likely to choose.
Where to buy
Rejuran Biome Healer Youth Formula Ampoule
The Youth Formula Ampoule was the formula that surprised me most while comparing the Rejuran lineup. While the other ampoules largely build on the original Turnover concept, this one takes a noticeably different direction.
Instead of focusing primarily on plant extracts or exfoliating ingredients, the formula combines ferments, ceramides, squalane, shea butter, and beta-glucan. Looking at the ingredient list, it feels more like a nourishing barrier-support serum that happens to contain c-PDRN.
Texture
The Youth Formula Ampoule stood out immediately because of its milky appearance. Unlike the other ampoules, which were mostly clear or translucent, this formula looked more like a lightweight emulsion serum.
The richer texture aligns closely with the formula's combination of lipids, ferments, and barrier-supportive ingredients.
Best For
✓ Normal skin
✓ Dry skin
✓ Mature skin
✓ Loss of elasticity
✓ Barrier support
If your skin is becoming drier with age or you prefer richer, more comforting textures, this is one of the most distinctive formulas in the Rejuran range.

Frequently Asked Questions
Can You Use More Than One Rejuran Ampoule in the Same Routine?
You can, but it is usually unnecessary. Since the formulas already overlap in c-PDRN and hydration, choosing one based on your main concern is usually simpler and more practical.
Can You Use Rejuran Ampoules With Retinol or Vitamin C?
Most of the formulas can fit into routines with retinol or vitamin C. I would be more cautious with the Pore Tightening Ampoule, because it already contains AHA, BHA, PHA, and LHA, so combining it with other strong actives may increase irritation.
Which Rejuran Ampoule Is Best for Sensitive Skin?
I would generally look toward the more barrier-focused formulas, such as the Dual Effect or Moisture Treatment Ampoule, rather than the exfoliating Pore Tightening version. Your individual tolerance still matters, especially if your skin is already irritated.
Are Rejuran Ampoules the Same as Rejuran Injections?
No. Rejuran ampoules are topical cosmetic products, while professional Rejuran procedures involve injectable polynucleotides or PDRN delivered directly into the skin. You should not expect a topical serum to produce the same effects as an in-clinic procedure.
Do You Need to Use a Rejuran Ampoule Every Day?
Most of the hydrating and barrier-focused formulas can be used regularly if your skin tolerates them well. The Pore Tightening Ampoule may need a slower introduction because of its combination of exfoliating acids.
Final Thoughts
After comparing the formulas side by side, my biggest takeaway is that the Rejuran ampoules are far more different than they first appear.
At first glance, the lineup looks like a collection of similar serums built around the same c-PDRN technology. However, a closer look at the formulas reveals products designed for very different goals. The Moisture Treatment Ampoule is clearly focused on barrier support and hydration, the Pore Tightening Ampoule takes an exfoliation-first approach, Triple Radiance emphasizes brightening, and the Youth Formula stands apart with its combination of ferments and nourishing lipids.
While c-PDRN may be the common thread running through the entire range, I found that the supporting ingredients tell the more interesting story. In practice, they are what truly determine how each ampoule feels, who it is best suited for, and where it fits within a skincare routine.
