May Cause Irritation
People with sensitive skin, eczema, or rosacea are more likely to experience:
- Redness
- Burning
- Itching
- Stinging
Not a Proven Acne Treatment
Although baking soda may temporarily dry out pimples, there is no strong clinical evidence that it effectively treats acne. In fact, excessive drying can sometimes worsen breakouts by irritating the skin.
Can Increase Sensitivity
Damaging the skin barrier may make the skin more vulnerable to environmental irritants and reduce its ability to retain moisture.

How to Use Baking Soda Safely
If you choose to try baking soda, moderation is essential.
Patch Test First
Before applying it to your face:
- Mix a small amount of baking soda with water to form a thin paste.
- Apply it to a small area on your inner arm or jawline.
- Wait 24 hours.
- If irritation occurs, do not use it on your face.
Limit Frequency
If your skin tolerates it:
- Use no more than once every one to two weeks.
- Apply very gently—never scrub aggressively.
- Rinse thoroughly with lukewarm water.
- Follow immediately with a fragrance-free moisturizer.
Who Should Avoid It?
Avoid applying baking soda directly to the face if you have:
- Sensitive skin
- Eczema
- Rosacea
- A damaged or broken skin barrier
- Open wounds or cuts
- Active skin infections
These conditions can become worse after exposure to alkaline products.
Better Alternatives for Healthy Skin
Dermatologists generally recommend products specifically formulated for facial skin, such as:
- Gentle facial cleansers
- Mild chemical exfoliants containing lactic acid or salicylic acid
- Niacinamide serums for oil control
- Vitamin C for brightening
- Broad-spectrum sunscreen (SPF 30 or higher) every day
