Is Baking Soda a Good Exfoliant?
Is Baking Soda a Good Exfoliant? — generally no; baking soda is highly alkaline and can disrupt the skin's naturally acidic protective barrier, leading to dryness, irritation, and increased sensitivity. Although it is sometimes used as a gritty scrub, gentler pH-balanced chemical or physical exfoliants are far better suited to facial skin.
Key points
- Baking soda has a high pH around 9, well above skin's natural acidity of roughly 4.5 to 5.5.
- Repeated use can compromise the barrier, causing dryness, tightness, and heightened sensitivity.
- Its abrasive particles can cause micro-tears and irritation when scrubbed on delicate facial skin.
- Gentler alternatives include AHAs, BHAs, or fine cosmetic exfoliants formulated for skin's pH.
Frequently asked
Why does baking soda feel like it is cleaning my skin?
It removes surface oils and debris through abrasion and alkalinity, but that same action strips protective lipids and can leave skin worse off.
Is baking soda okay for occasional use?
Even occasional use risks barrier disruption for many people, so pH-appropriate exfoliants are a safer routine choice.
