Although evidence is limited, baking soda may offer a few temporary benefits when used cautiously.
1. Mild Exfoliation
A gentle paste may help remove dead skin cells, leaving the skin feeling smoother.
However, excessive exfoliation can damage the skin barrier.
2. Oil Removal
Because baking soda is alkaline, it can temporarily remove excess oil from the skin.
For people with oily skin, this may create a cleaner feeling, but overuse may actually trigger the skin to produce more oil.
3. Surface Cleansing
Baking soda can help remove dirt and residue from the skin’s surface, but it should not replace a gentle facial cleanser.
Can Baking Soda Remove Dark Spots?
There is no strong scientific evidence that baking soda fades dark spots or hyperpigmentation.
Dark spots usually improve with ingredients that have been studied for this purpose, such as:
- Niacinamide
- Vitamin C
- Azelaic acid
- Retinoids
- Sunscreen
Can It Treat Acne?
Baking soda is not a recommended acne treatment.
Although it may dry out pimples temporarily, it can also:
- Irritate the skin
- Damage the skin barrier
- Increase redness
- Cause dryness and peeling
Dermatologists generally recommend proven acne treatments instead, such as benzoyl peroxide, salicylic acid, or adapalene, depending on the individual’s needs.
Can It Remove Dark Circles?
No.
Dark circles under the eyes may result from:
- Genetics
- Lack of sleep
- Allergies
- Aging
- Thin skin
- Blood vessels showing through the skin
Applying baking soda near the eyes is not recommended, as it can cause significant irritation.
