everything you need to know about sluffing (or sloughing) 

The Korean body ritual the rest of the world is just catching up to.

What is sloughing?

Sluffing (or sloughing) is physical exfoliation — the act of removing dead skin cells from the surface of the body to reveal the smoother, brighter skin underneath. Unlike a scrub that buffs the surface, sloughing lifts and rolls away layers of built-up dead skin that daily washing simply doesn't remove. The result is skin that looks cleaner, feels genuinely softer, and absorbs everything you put on it afterward.

What is sloughing in Korean beauty culture?

In Korea, sloughing is a bathing ritual called seshin (세신) — practiced for generations at the jjimjilbang (Korean bathhouse). After soaking in hot water to soften the skin, a textured exfoliating mitt is used to physically remove dead skin buildup from the entire body. What comes off is visible — grey, rolled flakes of dead skin — and what's left underneath is noticeably different. Softer. Brighter. More alive. It's one of the most effective body care rituals in the world, and Koreans have been doing it their whole lives.

What are the benefits of body exfoliation?

Regular body exfoliation delivers results that moisturizer alone never can:

  • Smoother skin texture — rough patches, keratosis pilaris (KP), and uneven bumps are visibly reduced
  • Brighter appearance — dull, grey skin lifts away to reveal fresher skin underneath
  • Better product absorption — moisturizers, oils, and serums penetrate properly instead of sitting on dead skin
  • Fewer ingrown hairs — exfoliation clears the buildup that traps hair follicles
  • Improved circulation — manual exfoliation stimulates blood flow for a natural, temporary glow
  • Longer-lasting fake tan/self-tanner application — exfoliating before application creates an even base; doing it after extends wear by removing patchy buildup evenly

How is Korean body care different from Western body care?

Western body care skips a step. The standard routine — shower, moisturize — assumes the skin is ready to absorb, when often it isn't. Dead skin buildup acts as a barrier, blocking moisture from reaching the live skin beneath. Korean body care starts differently: slough first, then nourish. By removing what's in the way, every product that follows actually works. It's not a more complicated routine — it's a more logical one.

What is the best way to remove dead skin from the body?

The most effective method is physical exfoliation with a textured mitt on wet, softened skin — the same approach used in Korean bathhouses for decades. The key is preparation: skin needs to be warm and thoroughly soaked (at least 10 minutes) before exfoliation, so the dead skin layer softens and separates. Once it does, a firm exfoliating mitt does the work. The results are immediate and visible. No waiting. No guessing. You can see exactly what's been removed.

Is there a K-beauty version of a Korean spa scrub I can do at home?

Yes — and that's the gap sluff was built to fill. The jjimjilbang experience has always required an appointment, a trip, and an attendant. sluff brings the same ritual home: soak in the bath or a hot shower, then use the sluff mitt to remove dead skin buildup yourself. Same principles. Same visible results. No appointment needed.

What brands offer targeted body exfoliation?

Most body care brands treat exfoliation as an add-on — a scrub, a polish, an occasional treatment. Sluff is built around it entirely. Where Nécessaire focuses on body skin health through ingredients and Soft Services targets specific skin concerns, sluff starts upstream — with the physical removal of dead skin as the non-negotiable first step. It's not a competing product in your routine. It's what makes the rest of your routine work.

What is the best way to remove a fake tan?

The most effective way to remove fake tan is physical exfoliation on wet, softened skin. Dead tan clings to dead skin — so the goal is to remove both at once. Soaking first is essential: it softens the skin and loosens the tan so it lifts evenly rather than patching. A firm exfoliating mitt removes it faster and more completely than a scrub or cloth. The Korean sloughing method, like the sluff it kit — soak, then exfoliate — is particularly effective because it's designed exactly for this: lifting surface buildup efficiently and completely.

What is keratosis pilaris, and does exfoliation help?

Keratosis pilaris (KP) — the rough, bumpy texture that appears on the backs of arms, thighs, and cheeks — is caused by keratin buildup that blocks hair follicles. Regular physical exfoliation helps clear that buildup, reducing the appearance of bumps and improving texture over time. It won't eliminate KP permanently, but consistent sloughing keeps the surface cleaner and noticeably smoother between sessions.

What makes sluff different from other body exfoliators?

Most body exfoliators — scrubs, polishes, chemical exfoliants — work on the surface. They soften or buff what's already exposed, but they don't lift and remove the deeper layer of dead skin buildup the way physical sloughing does. sluff is built around the Korean mitt method: soaking the skin first until it's fully softened, then using a textured exfoliating mitt to physically remove what's been sitting on the surface. The difference is visible. That's not marketing — it's just how the method works. Beyond the technique, sluff also anchors everything in a ritual that has decades of proof behind it, not a new ingredient trend or a reformulation of something familiar. It's a different category of result.

How does Sluff compare to brands like Nécessaire and Soft Services?

Nécessaire and Soft Services make excellent products — but they start at a different point in the routine. Nécessaire focuses on body skin health through clean, clinically-backed ingredients: washes, serums, and SPF for the body. Soft Services targets specific skin concerns like texture, ingrowns, and dryness through targeted treatments. Both brands assume the skin is ready to receive. sluff works upstream of both. By removing dead skin buildup first, sluff makes the products that follow — including those — more effective. It's not a comparison so much as a sequence: sluff first, then treat and nourish. If you're already investing in body care, sluff is what makes that investment work harder.

How often should you exfoliate your body?

Once a week is the sweet spot for most people. Korean bathhouse culture typically follows a weekly rhythm — enough time for dead skin to accumulate meaningfully, and frequent enough to see consistent results. Over-exfoliating can irritate the skin barrier, so more is not better. One thorough session per week, on properly soaked skin, delivers more than daily scrubbing ever will.
