Dry Brushing 101: What It Actually Does for Your Skin
Dry brushing is exactly what it sounds like — brushing dry skin with a firm-bristled brush before showering — and the actual evidence behind it is more modest than the wellness world suggests. It does genuinely exfoliate and can temporarily improve skin texture, but the more dramatic claims around circulation and detoxification don't hold up to much scrutiny.
What Dry Brushing Actually Does
The clearest, best-supported benefit of dry brushing is mechanical exfoliation. Dragging a firm brush across dry skin physically lifts away dead skin cells, which is why skin often feels smoother immediately afterward — the same reason any physical exfoliant works. It can also temporarily increase blood flow to the area being brushed, simply from the friction and stimulation, similar to what happens with a vigorous massage.
What it doesn't do, despite the claims that circulate around it, is meaningfully "detoxify" the body or significantly impact the lymphatic system in any way that's been well demonstrated. The skin's role in detoxification is limited regardless of how it's stimulated, and most of the stronger claims made about dry brushing outpace the actual research.
What It's Genuinely Good For
- Mechanical exfoliation, particularly for rough patches on elbows, knees, and heels
- Temporarily smoother-feeling skin immediately after brushing
- Helping body lotion or oil absorb more effectively afterward, since exfoliated skin takes in moisture better than skin with a layer of dead cells sitting on top
How to Do It Properly
Use a brush with natural, firm but not harsh bristles, and always brush on completely dry skin, before showering rather than after. Work in long strokes toward the centre of the body, starting at the feet and moving upward, using light to moderate pressure — enough to feel the exfoliation, not so much that skin turns red or feels raw. Two to three times a week is generally enough; daily use, especially with firm pressure, increases the risk of irritation without adding much benefit.
Who Should Be Cautious
Dry brushing isn't suited to broken, sunburnt, or actively irritated skin, and anyone with eczema, psoriasis, or generally sensitive skin should approach it carefully or skip it altogether — the mechanical friction that exfoliates can just as easily aggravate an already-compromised barrier.
After Brushing
Follow with a proper shower and a genuinely hydrating body lotion or oil while skin is still slightly damp — this is where the exfoliation actually pays off, since product absorbs more effectively into freshly brushed skin than it would otherwise.
Building It Into a Routine
- Dry brush before showering, two to three times a week, using light to moderate pressure
- Shower as normal
- Apply body lotion or oil while skin is still slightly damp
- Clean the brush regularly to avoid buildup of dead skin and bacteria on the bristles
When to See a Dermatologist
If you have a diagnosed skin condition like eczema or psoriasis, it's worth checking with a dermatologist before introducing dry brushing, since the mechanical exfoliation can sometimes worsen these conditions rather than help.

FAQ
Does dry brushing reduce cellulite?
There's no strong evidence it does — any temporary smoothing effect is more likely from exfoliation and brief increased blood flow than any meaningful change to fat or connective tissue.
How often should I dry brush?
Two to three times a week is generally enough. Daily brushing increases irritation risk without adding meaningful extra benefit.
Can I dry brush my face?
It's not recommended — facial skin is thinner and more reactive than body skin, and a body dry brush is too harsh for that area.
