That claim is misleading. Baking soda is not a safe or effective treatment for dark spots, wrinkles, or dark circles.
Baking soda (Sodium bicarbonate) is highly alkaline, while healthy skin is naturally slightly acidic. Using it on your face can actually damage the skin barrier.
Why baking soda is a bad skincare “hack”
1) Disrupts skin pH
- Skin’s natural acidity protects against irritation and infection
- Baking soda raises pH → weakens that barrier
2) Can worsen dark spots
- Irritation can trigger post-inflammatory hyperpigmentation
- This can make spots darker, not lighter
3) Does NOT treat wrinkles
- Wrinkles are caused by collagen loss
- Baking soda does not rebuild or stimulate collagen
4) Can irritate sensitive areas
- Especially around eyes (dark circles area)
- May cause burning, redness, dryness
What about “instant results” claims?
Any “brightening” people see is usually:
- Temporary dryness (skin looks tighter briefly)
- Mild surface exfoliation
- Not real removal of pigmentation or wrinkles
Safer, evidence-based options
For dark spots
- Sunscreen daily (most important)
- Vitamin C serums
- Niacinamide
- Retinoids (retinol)
For wrinkles
- Sunscreen (prevents worsening)
- Retinoids (best evidence)
- Moisturizers with hyaluronic acid
- Good sleep and hydration
For dark circles
Depends on cause:
- Lack of sleep → rest
- Pigmentation → vitamin C/niacinamide
- Hollow under eyes → cosmetic treatments may be needed
