Baking soda (sodium bicarbonate) is often promoted as a DIY skincare ingredient, but dermatologists generally recommend caution. While it has some potential uses, it can also irritate and damage the skin’s natural barrier.
Possible benefits
Some people use baking soda for:
- Mild physical exfoliation
- Removing excess oil temporarily
- Deodorizing skin
- Soothing itching from certain insect bites (when used appropriately)
However, evidence for routine facial skincare benefits is limited.
Risks of using baking soda on the face
The main concern is that baking soda is alkaline (pH around 8–9), while healthy skin is naturally slightly acidic (pH around 4.5–5.5). Regular use can:
- Disrupt the skin barrier
- Cause dryness and irritation
- Increase redness and sensitivity
- Worsen conditions such as eczema or rosacea
- Potentially trigger breakouts in some people
If you choose to try it
If you still want to test it:
- Mix a small amount with water to form a paste.
- Apply gently for a very short time.
- Avoid the eyes and broken skin.
- Rinse thoroughly.
- Follow with a moisturizer.
- Stop immediately if irritation develops.
Perform a patch test on a small area first.
Better alternatives
For exfoliation and smoother skin, products formulated for facial use are usually safer and more effective:
- AHAs (such as glycolic or lactic acid)
- BHAs (such as salicylic acid)
- Polyhydroxy acids (PHAs) for sensitive skin
- Gentle facial cleansers and moisturizers
For specific concerns
- Acne: Salicylic acid or benzoyl peroxide are generally better supported by evidence.
- Dark spots: Ingredients like niacinamide, vitamin C, azelaic acid, or retinoids are often more effective.
- Milia: Retinoids and professional extraction are typically better options than baking soda.
In short, baking soda is not usually considered a safe or ideal ingredient for regular facial skincare. Occasional use may be tolerated by some people, but it carries a meaningful risk of irritation and skin-barrier
