Sodium Bicarbonate on the Face: Benefits, Risks, and How to Use It Safely
Sodium bicarbonate (baking soda) is a common household ingredient that has become popular in skincare routines due to its exfoliating and cleansing properties. However, while it may offer some benefits when used carefully, it is also a substance that can disrupt the skin’s natural balance if misused.
Potential benefits
When used in very small amounts and with caution, sodium bicarbonate can:
- Act as a gentle exfoliant, helping remove dead skin cells
- Help reduce excess oil on the skin
- Provide a temporary feeling of freshness and cleanliness
- Assist in mild cleansing of clogged pores
Because of its slightly abrasive texture and alkaline nature, it may give the skin a smoother appearance after occasional use.
Important risks
Despite these potential benefits, sodium bicarbonate is not naturally compatible with facial skin. The skin has a slightly acidic protective barrier (known as the acid mantle), and baking soda is highly alkaline. This imbalance can lead to several issues:
- Skin irritation and redness
- Dryness and tightness
- Disruption of the skin’s natural protective barrier
- Increased sensitivity and risk of breakouts
- In some cases, worsening of acne or dermatitis
For people with sensitive skin, these effects can appear even after a single use.
