Baking Soda on the Face: Benefits, Risks, and How to Use It Safely
Baking soda (sodium bicarbonate) is a common household ingredient that some people use in DIY skincare. It is often promoted for exfoliation, acne, and skin brightening. However, while it may provide some short-term effects, it also carries risks that are important to understand.
Potential Benefits
1. Exfoliation
Baking soda has a fine, gritty texture that can help remove dead skin cells from the surface of the skin. This may leave the skin feeling smoother temporarily.
2. Oil Removal
Because it is mildly alkaline and absorbent, baking soda can remove excess oil from the skin, which may create a less shiny appearance.
3. Temporary Skin Smoothing
Some people notice smoother-feeling skin after using baking soda as a scrub, though this effect is usually temporary.
Risks and Side Effects
1. Disrupts the Skin Barrier
Healthy facial skin is naturally slightly acidic (typically around pH 4.5–5.5). Baking soda is highly alkaline (around pH 8–9), which can disrupt the skin’s protective barrier.
This may lead to:
- Dryness
- Irritation
- Redness
- Increased sensitivity
2. Can Worsen Acne
Although some people use baking soda for acne, irritation and barrier damage can actually make acne worse in some cases.
3. Over-Exfoliation
Frequent use may cause:
- Peeling
- Burning
- Inflammation
- Small skin tears from scrubbing
4. Not Suitable for Sensitive Skin
People with conditions such as:
- Eczema
- Rosacea
- Sensitive skin
may be more likely to experience irritation.
How to Use It More Safely
If you choose to try baking soda on your face:
- Mix a small amount with water to form a paste.
- Apply gently without vigorous scrubbing.
- Leave it on only briefly.
- Rinse thoroughly with lukewarm water.
- Apply a moisturizer afterward.
- Stop immediately if irritation occurs.
Avoid using it daily. Frequent use increases the risk of skin barrier damage.
Better Alternatives
For exfoliation and smoother skin, products specifically designed for facial use are generally safer and more effective, such as:
- Gentle cleansers
- Moisturizers containing ceramides
- Products with low concentrations of alpha hydroxy acids (AHAs) or beta hydroxy acids (BHAs)
- Salicylic acid products for acne-prone skin
Bottom Line
Baking soda may temporarily exfoliate and remove oil, but it can also irritate the skin and disrupt its natural protective barrier. For most people, specially formulated skincare products are a safer long-term choice. If you have sensitive skin, acne, eczema, or rosacea, it’s usually best to avoid using baking soda on the face.
