Your Cleanser and Moisturizer May Already Be Exfoliating You
Everyday cleansers and creams can quietly add acids that can leave skin dry and irritated.
Ordinary face wash and moisturizer can exfoliate skin without calling themselves exfoliants. That warning comes from Eve Casha, who writes the Skin, Investigated newsletter, in a guide to exfoliation published February 27, 2026.
Her line, in her words, is blunt: "Most people today are exfoliating their skin far more than they realize."
Casha argues the problem is not scrubbing too hard. It is buildup across a routine, where everyday products each add a little exfoliating power and the total becomes more than skin can comfortably handle.
She says when skin stays irritated, sensitive, or unpredictable despite good skincare, the answer may be cutting back rather than adding another product.
Part of the trouble is the label. The culprits include families of exfoliating acids, such as glycolic and lactic acids and salicylic acid and related forms, that a shopper may not recognize as exfoliants.
The same is true for other ingredients, Casha writes. She says alpha hydroxy acids added for moisture or antioxidant support still loosen dead surface cells, retinoids sold to support firmness still speed cell turnover, and azelaic acid used for uneven tone and redness also affects how cells shed.
Without noticing those extra effects, she argues, some people exfoliate every day or even several times a day without intending to. People may blame natural sensitivity, but Casha describes the result as overworked, inflamed skin that can feel dry and reactive.
As she puts it: "It is very common for skincare products to feature exfoliating active ingredients, but not mention it on its labeling or marketing … These can be considered hidden exfoliants!"
Questions people ask
How do I spot a hidden exfoliant on a label?
Look past the front label and read the full ingredient list. Watch for exfoliating acids such as glycolic, lactic, and salicylic acid, as well as retinoids and azelaic acid, even in products sold for moisture, aging, tone, or redness.
How often does Casha say to exfoliate?
Casha suggests that stronger acid products are often enough one or two times a week, or every seven to ten days for sensitive skin. People already using a daily retinoid or azelaic acid often do not need added exfoliation.
What should I do if my skin already feels over-exfoliated?
Pause added exfoliants, keep cleansing gentle, moisturize, and use broad spectrum sunscreen daily, since acids and retinoids can increase sun sensitivity. If burning, swelling, severe rash, or peeling persists, see a dermatologist.
