How much exfoliation is too much?

01 / The basics

What exfoliation is, and who it is for.

Exfoliation is the removal of dead skin cells from the outer layer of the skin. The American Academy of Dermatology notes that some people find it improves the look of their skin, that it is not for everyone, and that if it is not done properly it can do more harm than good.[1]

That is a useful starting position. Exfoliation is a choice, and a routine without it is not incomplete.

There are two main methods at home.[1]

Mechanical

A tool such as a brush, pad, sponge or washcloth, or a scrub, physically removes dead cells.

Chemical

Ingredients such as alpha and beta hydroxy acids dissolve them. See AHA, BHA and PHA: choosing an exfoliating approach and glycolic vs lactic acid.

02 / Frequency

Why there is no universal schedule.

Advice such as “twice a week” is everywhere. The AAD does not give a number. It says that how often you exfoliate depends on your skin type and the method, and that, generally, the more aggressive the exfoliation, the less often it needs to be done.[1]

It also matches method to skin.[1]

Dry, sensitive or acne-prone skin

May prefer a washcloth and a mild chemical exfoliator, because mechanical exfoliation may be too irritating.

Oily, thicker skin

May tolerate stronger chemical treatments or mechanical exfoliation.

Darker skin tones, or skin that marks easily

Avoid strong chemical or mechanical exfoliation. More aggressive forms can lead to dark spots on the skin.

So the honest answer to “how often” is: as often as your skin stays comfortable, and no more. Start low. If your skin is content with once a week, there is no reason to increase.

03 / A hidden total

What counts as exfoliation in your routine.

People who over-exfoliate rarely do it with one product. They do it with several, some of which they had not thought of as exfoliants.

• A cleanser containing salicylic or glycolic acid.
• An acid toner or “glow” pads.
• A scrub, or a cleanser with gritty particles.
• A cleansing brush, cloth or sponge used daily. See cleansing brushes and cloths: are they necessary.
• A peeling mask.
• A retinoid. The AAD notes that prescription retinoids, retinol and benzoyl peroxide can make skin more sensitive or cause peeling, and that exfoliating while using them may worsen dryness or cause breakouts.[1]

Write down everything on that list that you use and how often. The total is your real exfoliation frequency. For the retinoid question in particular, see retinol and exfoliating acids.

04 / Reading your skin

Signs you have gone too far.

The AAD warns that over-exfoliating can leave skin red and irritated.[1] Its guidance on keratosis pilaris adds that applying a chemical exfoliator too much or too often can cause raw, irritated skin.[3]

Redness

Colour that lingers after washing or applying products.

Stinging

Products that were comfortable begin to sting, including plain moisturiser.

Dryness and flaking

Skin feels tight and looks rough, the opposite of the intended result.

New breakouts

The AAD lists increased breakouts among the possible results of unsafe exfoliation.[1]

If the texture you were trying to smooth has become worse, more exfoliation is unlikely to be the answer. See rough facial texture: when exfoliation is not the whole answer.

05 / Stepping back

What to do if you have overdone it.

1. Stop exfoliating.

   All of it, including the products on the hidden list. The AAD’s advice when a chemical exfoliator leaves skin too dry or irritated is to stop using it for a few days.[3]

2. Keep the routine gentle.

   A mild cleanser, a moisturiser you tolerate and sun protection. The AAD notes that exfoliating can be drying and recommends moisturiser straight after.[1]

3. Wait until your skin is comfortable.

   There is no fixed period. Let comfort decide.

4. Return one product, less often.

   Choose the mildest and use it less frequently than before. See reintroducing products after irritation.

If stinging and redness continue once you have stopped, the question has moved on. Sensitive skin or a routine that has become too much covers the next steps.

06 / Technique and timing

When extra care is needed.

When you do exfoliate, the AAD’s technique is gentle: small, circular motions for about 30 seconds, then a rinse with lukewarm water. With a brush or sponge, use short, light strokes.[1]

Some situations call for holding back.

Broken or sunburned skin

Never exfoliate over open cuts, wounds or sunburn.[1]

Cold weather

A dermatologist quoted by the AAD recommends cutting back on products with alpha or beta hydroxy acids in winter, when they can irritate the skin even alongside moisturising creams.[2]

Sensitive skin

Skin that marks easily

Irritation can trigger dark marks in darker skin tones.[5]

The body

Skin on the body tolerates different methods from the face. See body exfoliation: scrubs, acids and skin tolerance.
