That claim is not supported by good skin science, and using baking soda on the face is actually one of the more common “viral skincare” ideas that can do more harm than good.
⚠️ The truth about baking soda on skin
Sodium bicarbonate (baking soda) is very alkaline, while your skin is naturally slightly acidic.
That matters because your skin’s acid barrier:
- protects against irritation and infection
- helps maintain hydration
- supports healthy skin repair
Baking soda can disrupt this barrier.
🚫 Why these claims are misleading
1) Dark spots
Dark spots (hyperpigmentation) don’t disappear from alkaline scrubs. In fact, irritation from baking soda can sometimes make them darker.
2) Wrinkles
Wrinkles are caused by:
- collagen loss
- sun damage
- aging
No topical kitchen powder can reverse that.
3) Dark circles
These are usually due to:
- genetics
- thin skin under the eyes
- poor sleep or allergies
Baking soda won’t fix these causes.
⚠️ Possible side effects of baking soda on face
- redness and burning
- dryness and peeling
- damaged skin barrier
- increased sensitivity
- worsened acne in some people
The under-eye area is especially too delicate for it.
🧴 What actually works (evidence-based)
For dark spots:
- Niacinamide
- Azelaic acid
- sunscreen (most important step)
For wrinkles:
- Retinol (gradual improvement)
- daily sunscreen
- moisturizers with ceramides
For dark circles:
- sleep + allergy management
- cold compress
- sometimes topical caffeine or retinoids (depending on cause)
🧭 Bottom line
Baking soda is not a safe or effective skincare treatment for dark spots, wrinkles, or dark circles. It may give a temporary “smooth” feeling but can damage the skin barrier over time.
If you want, tell me your skin concern (spots, wrinkles, under-eye darkness), and I can suggest a simple, low-cost routine that actually works.
