That kind of claim is mostly marketing, not reality.
Baking soda doesn’t “erase wrinkles overnight” or permanently remove blemishes. In fact, using it on your face—especially leaving it on overnight—can easily do more harm than good.
🧪 What baking soda actually is doing
Baking soda
It’s a strong alkaline substance. Your skin is naturally slightly acidic, which helps protect it.
When you apply baking soda to skin:
- It disrupts the skin barrier
- It can cause dryness and irritation
- It may trigger redness or sensitivity
- Over time, it can worsen breakouts for some people
❌ Why the “overnight wrinkle/blemish cure” claim is misleading
Wrinkles and blemishes don’t disappear overnight because they involve:
- Collagen structure changes (wrinkles)
- Oil production + bacteria + inflammation (acne)
- Pigmentation changes (dark spots)
A single topical mixture cannot realistically reverse these in hours.
⚠️ What can actually happen if you leave it on overnight
Instead of “glow skin,” people often experience:
- Tight, dry skin
- Flaking
- Red patches
- Increased sensitivity in the morning
🌿 What does help skin over time
If the goal is healthier skin texture, evidence-based options include:
- Gentle cleansing (not harsh scrubs)
- Sunscreen daily (biggest anti-wrinkle factor)
- Moisturizers with ceramides or hyaluronic acid
- Retinoids (for wrinkles and acne, if suitable)
- Balanced hydration and sleep
