Baking soda on the face is a popular internet “DIY skincare” idea, but it’s important to separate claims from reality.
🧪 What people claim (benefits)
Some posts say baking soda can:
- Exfoliate dead skin
- Lighten dark spots
- Reduce acne
- Make skin “smooth and bright”
⚠️ What actually happens (risks)
Baking soda is highly alkaline, while healthy skin is slightly acidic. This mismatch can:
- Damage the skin barrier
- Cause dryness, irritation, or burning
- Trigger redness and peeling
- Worsen acne or dark spots over time
- Increase sensitivity to sunlight
For conditions like pigmentation or uneven tone, such as melasma, irritation from baking soda can actually make it worse.
🚫 “Safe use” reality check
There is no dermatologically recommended safe way to use baking soda regularly on facial skin. Even diluted, it can still disrupt the skin barrier.
👍 What works better instead
If your goal is clearer or brighter skin, safer evidence-based options include:
- Gentle cleansers (pH-balanced)
- Sunscreen daily (most important step)
- Niacinamide for tone and oil control
- Vitamin C for pigmentation
