Ingredients Explained: Red Bean PDRN™ Skin Benefits

What Happens When PDRN Goes Hanbang?

Meet Red Bean PDRN™, our next-gen ingredient for pore care.

Chances are the letters “PDRN” have been popping up in your feed lately. It’s one of those skincare ingredients that started in clinical conversations and made its way into everyday skincare routines. It has a reputation for giving glow, bounce, and boosting skin vitality. As it moved from treatment rooms to bathroom counters around the world, everyone started asking: What is PDRN?

Originally known in clinical skincare spaces for deep renewal and improving skin quality, it’s now becoming a go-to in modern K-beauty formulations focused on comfort, balance, and anti-aging. So of course, we took it a step further.

Instead of simply following the trend, we wanted to bring it back to what inspires us most. Meet Red Bean PDRN™, our BOJ-exclusive twist that brings together the idea of PDRN skincare benefits with one of our most loved traditional Hanbang ingredients: red bean.

What is Red Bean PDRN™?

Red Bean PDRN™ isn’t simply red bean extract added to our formulas. This BOJ-exclusive ingredient is a vegan PDRN extracted from purified red bean DNA fragments.

Like typical PDRN derived from salmon DNA, it’s designed to support healthy-looking skin renewal and help skin appear smoother over time. But instead of an animal-derived source, Red Bean PDRN™ uses red bean as its foundation.

Red bean already has a long history in Korean skincare. For centuries, it’s been ground up to create a gentle exfoliant for soft, smooth skin. Red beans are also packed with saponins, which help absorb excess oil and leave skin hydrated and balanced. With our vegan PDRN from red beans, we were able to connect a modern skincare category with something deeply rooted in our heritage.

To go from bean to bottle, we start with untreated red beans and rapidly cool them with liquid nitrogen. This method allows us to finely crush the beans while keeping the plant-derived PDRN stable and pure. Then, we use mineral-rich deep sea water to extract key nutrients, separating the plant PDRN from the beans.

The red bean DNA we extract is a large molecule that sits on the surface of the skin. To ensure your skin can absorb it, we convert it to low-molecular-weight PDRN fragments. As a final touch, we purify the Red Bean PDRN™ with plant-derived nutrients to further boost stability.

It’s also a perfect example of what we love most about K-beauty innovation. Rather than choosing between traditional ingredients and modern technology, we bring them together.

Why Your Pores Will Love Red Bean PDRN™

When you think of pore care, you think about exfoliation and harsh treatments. For years, pore-focused routines have relied on strong acids, aggressive exfoliants, or oil-stripping ingredients that give you that tight feeling right away. While those approaches have their place, they aren’t the only way to care for skin.

We’ve always preferred a more balanced philosophy. Instead of focusing exclusively on removing what’s on the surface, we became interested in how supporting skin itself could help create a smoother-looking complexion overall.

That’s what makes Red Bean PDRN™ so exciting. Like typical PDRN, it supports healthy-looking skin renewal. When applied to areas where pores appear more visible, it helps refine their appearance and create a smoother-looking base without relying on ingredients that can leave skin feeling stressed or stripped. That’s because it helps support skin’s elasticity.

After all, pores are a natural part of healthy skin. Our goal isn’t to erase them. It’s to help your skin look smoother, more balanced, and more refined.

Red Bean PDRN™ Benefits for Skin

As skin loses elasticity over time, the areas surrounding pores can begin to look less firm, making pores appear more noticeable. That’s where our approach comes in.

Instead of relying on aggressive exfoliation or stripping ingredients, we focused on centering a pore refining ingredient that supports smoother-looking skin while staying gentle on the moisture barrier. The result is Pore Firming Serum: a silky, lightweight formula that targets the look of large pores while helping skin feel hydrated, balanced, and comfortable.

To help support the visibly refining effects of the formula, we paired Red Bean PDRN™ with a low-molecular-weight peptide. Peptides are known for supporting skin that looks firmer and more resilient over time, so they’re a perfect companion for PDRN. This combo makes Pore Firming Serum feel different from your typical pore care serum.

We put Pore Firming Serum through four different pore tests to see just how effective Red Bean PDRN™ is, and these were the results: 21.47% temporary improvement in pore count, 23.09% temporary improvement in pore volume, 25.79% temporary improvement in pore area, and 15.22% temporary improvement in pore depth.* Red Bean PDRN™’s benefits go beyond just helping just your pores. Pore Firming Serum gives a 13% improvement in skin texture, a 24.38% improvement in skin temperature (cooling effect), and a 12.21x improvement in the appearance of skin puffiness*. Put them together, and you’ve got that smooth, glass-skin look.

This formula feels hydrating and silky from the moment you apply it, and it fits perfectly with the rest of your red bean-inspired skincare ritual.

How Red Bean PDRN™ Fits Your Skincare Routine

PDRN is one half of the equation, but red bean is just as important. Long before Red Bean PDRN™ became part of the family, red bean was already at the heart of our approach to balancing skin that feels oily, congested, or uneven. That's why this ingredient layers so effortlessly into the routines you know and love.

Our Red Bean Pore Care Trio starts with Red Bean Refreshing Pore Mask. Formulated with red bean and kaolin clay, it washes away buildup while leaving your skin refreshed, comfortable, and smooth (never tight and dry). Follow with Pore Firming Serum, our Red Bean PDRN™ and peptide for smooth, gentle pore care. Finish with Red Bean Water Gel for lightweight hydration that feels especially comfortable for oily and combination skin types, thanks to red bean.

This routine centers balance, comfort, and smooth-looking skin with none of the dryness or irritation. They all share the same philosophy: supporting skin without overwhelming it.

You’ve probably been waiting for a BOJ PDRN formula. And it sticks to our unique Hanbang heritage. Some skincare trends disappear as quickly as they arrive, but we know Red Bean PDRN™ is here to stay.

We’ve combined one of Korean skincare’s most exciting innovations with one of Korean beauty’s most beloved traditional ingredients. Pore care from the future? We’re in.
