Body Exfoliation: What a Good Scrub Does for Smoother Skin (and What It Does Not)

Body Exfoliation: What a Good Scrub Does for Smoother Skin (and What It Does Not)

Body skin is easy to forget until it feels rough or looks dull. A good scrub is one of the simplest ways to bring it back, as long as you know what it can and cannot do.

What a scrub actually does

Exfoliation works by removing part of the outermost layer of dead skin cells, the stratum corneum. Research on mechanical skin treatments found that a professional method like microdermabrasion removes roughly a quarter of the stratum corneum, about 23 percent, in a single treatment (Kaushik and Keck, 2021, PMID 34508806). A sugar or salt body scrub is a gentler at-home version of the same idea: the granules loosen and sweep away surface dead cells so skin feels smoother and looks brighter.

For rough, bumpy skin

If your upper arms or thighs feel like fine sandpaper, that is often keratosis pilaris, a very common and harmless build-up of keratin around the hair follicles. A review found that keratolytic ingredients, the alpha and beta hydroxy acids and urea, can help by loosening that built-up keratin and improving the hydration of the surface skin, though it noted the overall evidence base is limited (Dampa, 2025, PMID 41631232). Physical scrubbing alone often is not enough for this, so a gentle acid or urea product can be a useful addition.

What a scrub does not do

A scrub does not detox the skin, and more is not better. Scrubbing too hard or too often can leave skin irritated and the barrier weaker, the same lesson that applies to over-exfoliating the face. Once or twice a week is plenty for most people.

The step most people skip

The real payoff comes from what you do next. Moisturise straight after your scrub, ideally on slightly damp skin, so you seal water in while the surface is freshly smoothed. A scrub followed by a rich body butter or a body lotion is the pairing that leaves skin genuinely soft.

At Verdo we stock the Pure Fiji Sugar Scrub, the Pure Fiji Coconut Crush Scrub, the Pure Fiji Body Butter, and the Pure Fiji Body Lotion to moisturise afterwards.

Frequently asked questions

What does a body scrub actually do?
A scrub physically removes part of the outermost layer of dead skin cells. Research on mechanical exfoliation found a professional method like microdermabrasion removes about 23 percent of the stratum corneum in one treatment (Kaushik and Keck, 2021). A home sugar scrub is a gentler version that loosens surface dead cells so skin feels smoother.
How often should I exfoliate my body?
For most people once or twice a week is plenty. Scrubbing too hard or too often can irritate the skin and weaken its barrier, the same problem that applies to over-exfoliating the face. Gentle and consistent beats aggressive.
Will a scrub fix bumpy skin on my arms?
Those rough bumps are often keratosis pilaris. A review found keratolytic ingredients such as alpha and beta hydroxy acids and urea can help by loosening the built-up keratin, though the evidence base is limited (Dampa, 2025). Physical scrubbing alone often is not enough, so a gentle acid or urea product can help.
What should I do after exfoliating?
Moisturise straight after, ideally on slightly damp skin, to seal in water while the surface is freshly smoothed. A scrub followed by a rich body butter or lotion is what leaves skin genuinely soft, so do not skip that step.
