Do razors exfoliate your skin?

What kind of exfoliation does a razor do?

A razor acts as a mechanical exfoliant: a tool physically removes dead surface cells. Chemical exfoliants, such as alpha and beta hydroxy acids, loosen or dissolve dead cells instead. Shaving and dermaplaning can both exfoliate, but neither is automatically a good choice for every face. A razor remains a hair removal tool, even when the skincare vocabulary gives it a promotion.12

How to shave without adding unnecessary irritation

1. 1Wet your skin and hair first. Right after a shower is a useful time because the hair is softer and your skin is warm, moist and free of excess oil and dead cells that can clog the blade.
2. 2Apply shaving cream or gel. For very dry or sensitive skin, choose a shaving cream labelled for sensitive skin.
3. 3Use a sharp blade and shave lightly in the direction the hair grows. Do not try to shave off acne.
4. 4Rinse the razor after every swipe. Replace the blade or discard a disposable razor after 5 to 7 shaves to reduce irritation.
5. 5Apply moisturizer afterwards to help counter the drying effect of exfoliation.
6. 6Store the razor somewhere dry, not in the shower or on a wet sink. Let it dry completely between uses to prevent bacterial growth.

Do you still need a scrub or exfoliating acid?

Not automatically. Exfoliation is optional, and the right frequency depends on your skin and the method you use. Treat shaving as part of your exfoliation routine rather than ignoring it when deciding how much more to add. More aggressive exfoliation calls for less frequent use, not a fuller calendar. Too much exfoliation can leave skin red and irritated. Facial acids can also remove structures that retain water and healthy fats when overused. If you use exfoliating facial acids, apply SPF 30 or higher sunscreen every day because they increase susceptibility to sun damage.24

Who should be careful?

Mechanical exfoliation can be too irritating for dry, sensitive or acne prone skin. Prescription retinoids, retinol and benzoyl peroxide can already make skin sensitive or cause peeling; adding exfoliation can worsen dryness or breakouts. Avoid aggressive exfoliation if you have darker skin or develop dark marks after irritation, because it can increase pigmentation. For facial acne, try an electric or disposable blade razor to find which is less irritating.23

When should you stop?

Stop adding exfoliation if your skin becomes red or irritated. Do not exfoliate over open cuts, wounds or sunburn. If shaving worsens acne, or you cannot work out a tolerable shaving and exfoliation routine, a dermatologist can help you choose a suitable approach.23
