We Made This K-Beauty Ingredient Just For Our New Body SPFs

Meet hydrating, glow-boosting Fermented Brown Rice™.

Rice has been a cornerstone of Korean skincare for generations, and Korean rice skincare is no stranger at Beauty of Joseon. You’ll find rice in some of our most-loved formulas, from Relief Sun to Dynasty Cream. The benefits of rice for skin are real. It’s gentle, glow-giving, and good for just about every skin type.

For our new (and first) body sunscreens, we wanted to do something different. How could we take rice even further, and make it work harder for skin from the neck-down that doesn’t usually get a real ritual?

This led us to Fermented Brown Rice™, our BOJ-exclusive take on this classic K-beauty ingredient. Here’s what makes it different, and why it’s the secret behind both of our body SPFs.

White Rice vs. Brown Rice Benefits: What’s different?

You might have your preference for brown or white rice when you’re cooking. They taste different and have different nutrients—and it’s the same in skincare (please don’t taste your sunscreen!).

If you’ve used our iconic, TikTok-viral Relief Sun SPF, you know we love white rice extract. It’s gentle, it gives that signature K-beauty glow, and feels ultra-light on your skin. It’s an everyday glow ingredient.

Brown rice is different, beyond the color. It’s whole, unpolished rice that still has its bran layer, which means it’s naturally richer in fiber, minerals, and antioxidants. That’s where the rice bran oil benefits for skin come in. The bran layer is what gives brown rice its more nutrient-rich properties, making it especially good for elasticity, anti-aging support, and overall skin health.

It’s not that one is better. They just do different things. We picked brown rice to formulate our Fermented Brown Rice™ to give your body skin some extra TLC.

Why Your Skin Will Love Fermented Brown Rice™

You’re probably applying any SPF to your body and calling it a day. No serum, no targeted treatment, no real skincare moment.

Your arms, legs, neck, and shoulders are some of the most UV-exposed areas on your body. Without any real skincare attention, they can quietly start showing signs of dehydration, aging, and dullness.

That’s the gap we wanted to fill. Our body sun lotions are designed to do double duty: protect from UV damage and treat skin like it actually deserves to be treated. The rice benefits for skin you already love in your face routine? We wanted them on the rest of you, too.

Fermented Brown Rice™ Benefits for Skin

Here’s the good stuff. Let’s get into what Fermented Brown Rice™ actually does for your skin, and why we built body lotion with SPF around it.

First, fermented rice delivers antioxidant-rich nourishment where you need it most. Brown rice’s bran layer is loaded with polyphenols, vitamins, and other antioxidants that help defend skin against the everyday environmental stressors that add up (UV exposure, pollution, all of it).

Fermentation makes those nutrients even more potent and plentiful, so your skin can soak them up and show the results. The areas that get the most sun (and the least skincare attention) finally get a daily dose of antioxidant care when you use our sunscreen for body.

Comfort Protection Mineral Body Sun Lotion SPF 40 pairs Fermented Brown Rice™ with panthenol, our favorite ingredient for deep hydration that creates a moisture veil to make it last. So your skin not only absorbs essential moisture, but also holds onto it. The result is a soft, soothing, deeply moisturizing synergy that’s gentle enough for reactive skin. And we have the science to prove it: there’s a 29.32% reduction in skin irritation caused by UV exposure when you use Comfort Protection Mineral Body Sun Lotion SPF 40.*

Fermented Brown Rice™ also supports elasticity and that bounce-back, glowy look. Those nutrients unique to brown rice? They help support your skin’s elasticity over time. Fermentation amps up the amino acid and peptide content, both of which are key to keeping skin looking smooth and resilient.

That’s why we paired it with a ceramide in Hydra Shield Body Sun Lotion SPF 50+. Ceramides are lipids already found in your skin barrier, keeping it supported. You might hear ceramides and think of heavy, greasy creams. But you know how we do things at BOJ. This formula stays super lightweight, even though it’s moisture-rich. Paired with Fermented Brown Rice™, it gives this formula a body-lotion-level hydration payoff alongside SPF 50 protection. It’s even clinically proven to build up hydration the more you use it. There’s a 464.37% improvement in skin moisture after 3 uses.**

Like all of our favorite ingredients, it’s also super lightweight and never sticky. Fermentation makes Fermented Brown Rice™ smaller and fast-absorbing, which means it sinks into skin easily, rather than sitting on top of it. The result is hydrating formulas that feel weightless and fresh, like you’ve applied a body essence and sunscreen in one step.

When you use Fermented Brown Rice™ consistently in your skincare routine, you’ll notice natural radiance, bounce, and replenished hydration.

How Fermented Brown Rice™ Fits Your Skincare Routine

Fermented Brown Rice™ fits in with your daily Korean skincare routine like it’s been there all along. Apply your chosen body SPF generously in the morning, and reapply every two hours. Don’t forget the spots that tend to get skipped (but get a lot of sun), like the backs of your hands and the tops of your feet.

If you’re most excited about the soothing benefits of Fermented Brown Rice™, reach for Radiance Cleansing Balm to start your skincare routine. It’s a gentle, hydrating, rice-infused cleanser. Then, apply Ginseng Essence Water to boost bounce and glow. Opt for Dynasty Cream, our iconic rice-powered moisturizer. Then, use our TikTok-viral, rice infused Relief Sun SPF for a soothing, hydrating touch. Finish with Comfort Protection Mineral Body Sun Lotion SPF 40 for gentle, hydrating, Fermented Brown Rice™-boosted body care.

Looking to glow? Cleanse with Green Plum Refreshing Cleanser to boost your barrier, then use Glow Replenishing Rice Milk to balance out skin and get a rice radiance boost. Follow with Red Bean Water Gel for a lightweight, oily-skin friendly touch, then reach for Relief Sun Aqua-Fresh, the lighter version of our iconic Relief Sun. Reach for Hydra Shield Body Sun Lotion SPF 50+ for naturally radiant body skin.

There’s a reason fermentation is a superstar in Korean skincare. It’s how foods get better with time and develop depth, and how a handful of brown rice becomes something your skin drinks up.

Fermented Brown Rice™ takes a nutrient-rich ingredient and unlocks its full potential, for nourishment that actually gets in and gets to work.
